Description
Borne tunnel MC21 pour compact boitier moulé taille M1, 1 terminal : 4-95mm²
•Les Atouts de l'article:
Accessories suitable for Moulded Case Circuit Breakers Ex9M. It is possible to supplement or modify functionsof a basic circuit breaker by installing of suitable accessories.Circuit breakers can be equipped with auxiliary contacts AX21 (up to 2 units even for M1 frame size) and oneunit of signal contact AL21 or early make auxiliary contact EC 2i. AX21 and AL21/EC 2i are mounted into differentpositions, a use of one type of the contact does not limit a number of the second type. AX21 and AL21/EC 2i can be used regardless the frame size of the circuit breaker.One unit of undervoltage release UVT2i or one unit of shunt trip relase SHT2i can be installed in the breaker.Diff erent versions for diff erent frame sizes allow to optimise power comsumption of these units.The circuit breakers can also be equipped with diff erent accesories for operation of the toggle. There areavailable direct rotary handle, rotary handle with extended shaft e.g. for door coupling and a motor operator.Mounting of the device onto plate can be done directly with the screws which are included in the scope ofdelivery. Or in case of M1 and M2 devices there is possibility to use adaptors DRA for mounting onto DIN-rail35 mm. If it is requested to place devices of diff erent frame size side by side, it is possible to use for compensationof diff erences in height mounting depth spacers WG which assure the same position of front paneltowards front plate.For connection of conductors there are available various types of box and tunnel terminals MC.
