eVM1 “the integrated circuit-breaker” Magnetic actuator integrated circuit-breaker with sensors, protection and control on board 12...17.5 kV - 630...1250 A - 16...31.5 kA eVM1 medium voltage integrated circuit-breaker The eVM1 integrated MV circuit-breaker is based An optional communication module enables on the proven VM1 series of vacuum circuit- monitoring, configuration and full remote control, breakers with magnetic drive. thereby reducing on-site supervision and Current sensors are fitted on the pole contact arms traditional secondary wiring. and current signals are cabled directly to the The software configuration tool provides a way to integrated electronic control device on board the configure the circuit-breaker in order to view and/ circuit breaker. or modify the set of parameters for the protections, The electronic controller supervises all the circuit- communication and general settings and makes it breaker functions, from magnetic drive operation possible to supervise the whole panel status. to protection. Energy storage monitoring for Open-Closed-Open It monitors the whole panel status (circuit-breaker, cycle, drive coil continuity and system readiness, switch-disconnector and earthing switch) and incorrect positions or incongruous states for the controls its own functional reliability. cir
