Spectronic Air Circuit Breaker Operating Instructions

ProtectionRMS7 Trip• If the circuit breaker is to be reset in local mode,it must be reset manually after an overcurrentcondition by pushing in fully the local trip pushbutton 13.

Description :Powered by the current transformers, lmax = 4000, the RMS7 unitperforms all the necessary current protections with true rms value sensing:• overload protection (LT)• short-circuit protection (ST and I)• ground fault protection (GF) (The 4th (neutral) current transformer must be of the same rating as those of the three phases).

RMS7 : OptionsThe following options are field fittable

Distinct Fault Signalling (LT, ST, I, GF)• Local indication by LED display. this option is power supplied by an internal battery.• Lead sealing.

1 - Arrival

When packages arrive, check that they are inperfect condition. If otherwise, proceed with theusual notifications.Do not hesitate to proceed with unpacking in thepresence of an authorized agent representing thedelivery firm.

2 - Storage

If the equipment is not installed immediately, itmust be stored in a premises where it is protectedfrom dust and splashing by water. To avoid anydeterioration, it is recommended that equipmentbe left in its protective covering or provided witha waterproof covering.

3 - UnpackingS800-2500 / S3200-4000

Withdrawable* breaker with cradle• Remove the 2 supports (A) securing the

circuit-breaker onto its fixed section on

either sides

• Remove the 4 brackets (B) securing the fixed

section onto the base of the packing case.

• Remove the 2 brackets (C) protecting the

front box (cradle).

* Fixed breaker : remove the 4 attachment

screws at the base of the breaker fixed to

the woden pallete.

Withdrawable* breaker withoutcradleThe handles on the upper section of the sideflanges may be used to lift the equipment.Never carry the circuit-breaker by its cut-offclamps. Rest it on a flat surface, either on itslower section or on its side flanges. Keep thebase of the packing case for use as a palette.

Circuit breaker position• “CONNECTED”Turn the crank as far as it will go in the clock-wise direction. Here the indicator will stop at“connected” position mark. In this position themain and auxiliary circuits are connected.

• “EXTRACTED MAINTENANCE (COMPLETELY WITHDRAWN) POSITION”Pull the retractable rails to fully extend themand pull the breaker as far as it will go.

Fitting the breaker :

• Turn the plug-in crank as far as it will go in

anti-clockwise direction.

• Pull the retractable rails out to the fully

extended position.

• Pull the breaker out on the rails using the

pulling handles.

• Push the breaker back and then the rails

fully home.

Electrically operated circuit breaker :• Press the “On” and “Off” push buttons in turnto release the energy stored in the spring.

Position-indicating contacts• “connected position” - 1 or 2 contacts actuated when circuit-breaker is fully plugged-in (32).• “withdrawn position” - 1 or 2 contacts actuated when circuit-breaker is fully removed (31).• 1 contact actuated on fitting and removing the crank (33).

Circuit Breakera - Manual Operation• reset the release- press the trip (OFF)push button (13) (BPDL) fullyin• resetting- operate the handle (11) to compress the spring(stored energy required for closing)- press the ON push-button (15)• closing- presence of voltage required on UV or UVRD iffitted on breaker.• opening- in local mode by trip push button (BPDL) (13)- in remote mode by voltmetric releases

b - Electrical OperationElectrical operation with stored energy : thestored energy is reset automatically once thebreaker has been closed.The trip push button (BPDL) (13) resets theovercurrent release except if the circuit-breakeris reset automatically, with or without indicationwith memory.• opening- in local mode, using the red trip (OFF) pushbutton (13)- in remote mode, using the voltmetric releases- if closing the breaker is provided by acontinuous command, the closing commandmust be momentarily interupted after trippingin order to obtain resetting• closing- in local mode, using the green ON push-button(15)- in remote mode by closing coil.

ProtectionRelease• If the circuit-breaker is to be reset in local mode,it must be reset manually after overload andshort-circuit operation by pressing the local trippush button BPDL (13) fully in.

Each protected pole of the circuit-breaker isequipped with current transformers (CT) whichsupply input to the releases RMS7 / RMS9D /LMZ7.

VIEW Button

- Indicates the battery status (battery ok when the “BAT” led is powered).

- Indicates the origin of fault (LTPU - GF - OVL - SHORT).

RESET Button

- Reset the fault indicator.

Trip Unit Healthiness : press and hold the view button for more than 5

seconds. If the LTPU LED blinks slowly, it indicates the healthiness of the tripunit.

CAUTION

- The battery can be replaced only by Panasonic CR1616 or Duracell DC1616B.

- Use of others battery can present a risk of fire, explosion or can damage the product.

- Check the polarity of the battery.

Fault Signal

LT : LED OVL : Tripping on overload condition

ST - I : LED SHORT : Tripping on short circuit condition

GF : LED GF : Tripping on ground fault condition

LTPU : LED Pre-alarm LT

The LTPU led blinks slowly when the LT threshold is below 100%.

The LTPU led blinks rapidly when the LT threshold is above 100% and indicatesan imminent tripping on overload condition.

Replacement

The “CLIC” sound at the end of installation operation indicates that the ratingplug is correctly installed on the unit.

ATTENTION

� The (S) rating indicated on the rating plug must be identical to the

nominal current indicated on the RMS7 unit.

Voltmetric ReleasesThe equipment can be equipped with 2 releasesof types EA (Shunt), UV or UVRD (Delayed UV).They are reset by the breaker’s main shaft at theend of the opening operation.

Inhibited ClosingClosing is prevented by Closing-PreventionDevice FE operating at minimum voltage and isindependent of UV release.

Auxiliary Contacts• Between 5 and 8 contacts operate at thebeginning of closing of poles.• Between 1 and 4 contacts operate at the sametime as the main poles.

2 - RevisionInspection is to be performed every 3000operations or 3 years (we recommend theintervention of the specialists in the service andverification for this revision).

A - Arc Chute• wipe the insulating cover

B - Poles

• Fixed and Withdrawable Breakers- remove dust from isolating parts- check the gap on arcing contacts with thecircuit-breaker closed.• repeat the adjustment of fixed arcing contactsif the gap is greater than 1,5 mm.

1 - MaintenanceThe arc chutes and arcing contacts ensure :• 1500 closing cut-out operations at In*• 3 closing/cut-out operations at maximumshort-circuit current*• 10 closing cut-out operations at 10 In*All other components are designed to last as longas the breaker ’s normal service life (20,000operations for the electrically-operated ormanual operated breaker).* In one of these cases : Remove the arc chutesand change the arcing contacts.Visual monitoring (every year) :• cleanliness of the circuit breaker.• cleanliness of grease (if the apparatus isexposed to dust)

3 - LubricationA - Components to be Lubricated• all metal/metal friction surfaces must be kept greased.• wipe off excess grease.• grease characteristics : High Speed Grease 475HS mfd. by OKS Industries, Bangalore, India.B - Components not to be lubricated• current-threshold and voltmetric release.

C - Disconnection of SecondaryWiringClean the fixed and movable contacts with acloth slightly dampened with carbontetrachloride.Check for contact pressure.Grease lightly.

D - Overcurrent and VoltmetricReleaseNo maintenance.In case of failure, replace the release.

• replace the arc barriers and the spark arrestersif they are worn by more than 1 mm• clean the surfaces of main contacts with fine-grain emery paper and wipe carefully.

• Removable BreakersClean the following parts with a cloth slightlydampened with carbon tetrachloride :- the cluster contacts- the studs for the cradleGrease lightly

Poles Tightening :The set of poles is maintained under pressure bysix rams located on each flange of the circuit-breaker. Check the tightening torque.
