MCCB Auxiliary Contact, 1 N/O 1 N/C | Onesto KCM1

The Onesto KCM1 Auxiliary Contact is a signalling accessory that fits onto a KCM1 MCCB to provide a remote indication of the breaker's position (open or closed). It is suitable for electricians, panel builders and control system integrators who need to feed breaker status back to a PLC, BMS, SCADA system or indicator lamp. Available sized to match the 100S, 225S, 400S, 630S, 800S or 1250S KCM1 MCCB frame, fitted to either the left or right mounting position.

• Application: Remote breaker status signalling for control panels, BMS and SCADA integration
• Key specification: 1 N/O (normally open) and 1 N/C (normally closed) contact
• Compatibility: Select the size matching your installed MCCB frame
• Mounting position: Available for left or right-side fitting
• Installation benefit: Two mounting positions allow a second accessory (e.g. shunt trip) to be fitted alongside on the same breaker

Key Features

• Provides a dry contact signal (1 N/O, 1 N/C) that mirrors the breaker's open/closed state
• Fits directly onto the matching Onesto KCM1 MCCB frame without modification
• Left and right mounting positions let you combine an auxiliary contact with a shunt trip or under-voltage release on the same breaker

Typical Applications

• Breaker status feedback to PLC, BMS or SCADA systems
• Remote indicator lamps showing breaker position
• Generator and changeover panel signalling
• Motor control centres requiring breaker status monitoring
