MCCB Alarm Contact | Onesto KCM5

The Onesto KCM5 Alarm Contact is a signalling accessory that fits onto a KCM5 MCCB to indicate when the breaker has tripped due to a fault, as distinct from a normal manual open/close operation. It is suitable for electricians, panel builders and control system integrators who need fault alarm signalling fed back to a PLC, BMS or SCADA system. Available sized to match the 160S, 250S, 400S, 630S, 800S, 1000S or 1250S KCM5 MCCB frame.
