Product Description
General
The VM1 circuit-breakers use vacuum interrupters embedded in the poles.
The embedded interrupters are particularly sturdy and protect the interrupters against shocks, accumulation of dust, and humidity. Each interrupter houses the contacts and makes up the interrupting chamber.
Actuation of the interrupter contacts is carried out by a single magnetic actuator controlled by position sensors and by an electronic module. The energy required for operation is provided by capacitors which ensure an adequate store of energy.
The electronic control circuit can be supplied in two versions: the "basic" one and the one with the "full options" which are characterized by:- high electromagnetic immunity
- self-diagnosis of the capacitor load and the continuity of the coils: controller watchdog with signaling of faults
- wide range of the auxiliary power supply in direct and alternating current
- low consumption for maintaining the capacitor load
- determination of the circuit-breaker state by means of proximity sensors
- monitoring of all the interruption functions.
Thanks to the use of the embedded interrupters and the magnetic drive, the VM1 circuit-breakers guarantee:- sturdiness
- reliability
- long life
- no maintenance
magnetic drive technology
the magnetic drive used in the VM1 circuit-breakers generates the run required to activate the moving contacts of the interrupters and integrates all the functions of a traditional drive.
The magnetic drive is a bistable system where the end-of -run positions of the moving armature are reached by means of magnetic fields generated by two coils( one for closing and one for opening).
The moving armature is kept in position by permanent magnets. General characteristics of fixed circuit-breakers
