This position isindicated when the required clearance for isolation of the power and auxiliary circuitsis reachedb changeover contacts to indicate the "test" position (CT). In this position, the powercircuits are disconnected and the auxiliary circuits are connected.Additional actuatorsA set of additional actuators may be installed on the chassis to change the functionsof the carriage switches.NTNWContacts CE/CD/CT CE/CD/CTMaximum numberStandard3 2 1 3 3 3with additional actuators9 0 06 3 06 0 3Breaking capacity (A)p.f.: 0.3AC12/DC12StandardLow-levelMinimum load: 100 mA/24 VV AC 240 8 8380 8 8480 8 8690 6 6V DC 24/48 2.5 2.5125 0.8 0.8250 0.3 0.3Minimum load: 2 mA/15 V DCV AC 24/48 5 5240 5 5380 5 5V DC 24/48 2.5 2.5125 0.8 0.8250 0.3 0.3M6C programmable contacts:circuit-breaker external relay with six independent changeovercontacts controlled from the circuit breaker via a three-wireconnection.M2C / M6C programmable contactsThese contacts, used with the Micrologic P and H control units, may be programmedvia the control unit keypad or via a supervisory station with the COM communicationoption. They require an external power supply module.They indicate:b the type of faultb instantaneous or delayed threshold overruns.b They may be programmed:b with instantaneous return to the initial stateb without return to the initial stateb with return to the initial state following a delay.CharacteristicsMinimum loadBreaking capacity (A)p.f.: 0.7V AC 240 5380 3V DC 24 1.848 1.5125 0.4250 0.15M2C/M6C100 mA/24 VDB101161M2C: 24 V DCpower suppliedby control unit(consumption100 mA).DB101170M6C: external 24 V DC power supply required(consumption 100 mA).47
