Charging the circuit breakerE60072AThe charge status is indicated as follows.O IPush OFFPush ONThe springs in the circuit breaker operating mechanism must be charged to storethe energy required to close the main contacts. The springs may be chargedmanually using the charging handle or automatically by the optional MCH gearmotor.Manual charging.Pull the handle downseven times until youhear a "clack".Automatic charging.If the MCH gear motor isinstalled, the spring isautomatically rechargedafter each closing.E51347AE46790AorMERLIN GERIN9Masterpact NT06-16 IECSchneider Electric

Using MasterpactClosing the circuit breakerE51292AE51291ADevice "ready to close"Device not "ready to close"Closing conditionsClosing (i.e. turning the circuit ON) is possible only if the circuit breaker is"ready to close".The prerequisites are the following:b device open (OFF)b springs chargedb no opening order present.The circuit breaker will not close unless it is "ready to close" when the orderis given.Closing the circuit breakerLocally (mechanical)Press the mechanical ON pushbutton.E60047AE51493AOPuPush OFFLocally (electrical)E60049ABPFEE51294AXFPress the electrical closingpushbutton. By adding anXF closing release, thecircuit breaker can be closedlocally.RemotelyE60048AE51294AXFWhen connected to a remote control panel, the XFclosing release can be used to close the circuitbreaker remotely.Anti-pumping functionThe purpose of the mechanical anti-pumping function is to ensure that a circuitbreaker receiving simultaneous opening and closing orders does not open andclose indefinitely.If there is a continuous closing order, after opening the circuit breaker remainsopen until the closing order is discontinued. A new closing order is required to closethe circuit breaker. A new order is not required if the closing release is wired inseries with the PF "ready to close" contact.10Masterpact NT06-16 IECSchneider Electric

Inspecting and testingbefore useInitial testsProcedureThese operations must be carried out inparticular before using a Masterpact devicefor the first time.A general check of the circuit breaker takes only a few minutes and avoids any riskof mistakes due to errors or negligence.A general check must be carried out:b prior to initial useb following an extended period during which the circuit breaker is not used.A check must be carried out with the entire switchboard de-energised.In switchboards with compartments, only those compartments that may beaccessed by the operators must be de-energised.Electrical testsInsulation and dielectric-withstand tests must be carried out immediately afterdelivery of the switchboard. These tests are precisely defined by internationalstandards and must be directed and carried out by a qualified expert.Prior to running the tests, it is absolutely necessary to:b disconnect all the electrical auxiliaries of the circuit breaker (MCH, MX, XF, MN,Res electrical remote reset)b remove the long-time rating plug on the 7.0 A, 5.0 P, 6.0 P, 7.0 P, 5.0 H, 6.0 H,7.0 H control units. Removal of the rating plug disconnects the voltagemeasurement input.Switchboard inspectionCheck that the circuit breakers are installed in a clean environment, free of anyinstallation scrap or items (tools, electrical wires, broken parts or shreds, metalobjects, etc.).Conformity with the installation diagramCheck that the devices conform with the installation diagram:b breaking capacities indicated on the rating platesb identification of the control unit (type, rating)b presence of any optional functions (remote ON/OFF with motor mechanism,auxiliaries, measurement and indication modules, etc.)b protection settings (long time, short time, instantaneous, earth fault)b identification of the protected circuit marked on the front of each circuit breaker.Condition of connections and auxiliariesCheck device mounting in the switchboard and the tightness of power connections.Check that all auxiliaries and accessories are correctly installed:b electrical auxiliariesb terminal blocksb connections of auxiliary circuits.OperationCheck the mechanical operation of the circuit breakers:b opening of contactsb closing of contacts.Check on the control unitCheck the control unit of each circuit breaker using the respective user manuals.40Masterpact NT06-16 IECSchneider Electric

What to do when the circuitbreaker tripsNote the faultFaults are signalled locally and remotely by the indicators and auxiliary contactsinstalled on circuit breakers (depending on each configuration). See page 12 in thismanual and the user manual of the control unit for information on the faultindications available with your circuit breaker.Identify the cause of trippingA circuit must never be reclosed (locally or remotely) before the cause of the faulthas been identified and cleared.A fault may have a number of causes:b depending on the type of control unit, fault diagnostics are available. See theuser manual for the control unit.b depending on the type of fault and the criticality of the loads, a number ofprecautionary measures must be taken, in particular the insulation and dielectrictests on a part of or the entire installation. These checks and test must be directedand carried out by qualified personnel.Inspect the circuit breaker following a short-circuitb check the arc chutes (see page 43)b check the contacts (see page 43)b check the tightness of connections (see the device installation manual)b check the disconnecting-contact clusters (see page 43).Reset the circuit breakerThe circuit breaker can be reset locally or remotely. See page 12 in this manual forinformation on how the circuit breaker can be reset.41Masterpact NT06-16 IECSchneider Electric
