Fill a gap in your power distribution system with this MCB blank from ABB. It's designed to fit into an open MCB slot on a DIN rail to prevent users from making accidental contact with live electrical parts. It also serves as a neat way to reserve the slot for future use. This unit is shaped like a standard circuit breaker, so it's a natural fit for your existing power board. It's built to take the strain of demanding settings, as it's made of tough plastic material.

• Easy to label for quick identification as a blank in crowded panels
• Integrated spring clip for easy installation and removal from the DIN rail
• Protects sensitive electrical parts from contamination

• HVAC systems
• Lighting controls
• Telecommunications
• Energy industry
• Electrical engineering

To install it, simply snap it onto your DIN rail as you would with a regular MCB. To avoid confusion, it's orientated differently to an active MCB, with its main DIN rail clip located at the back, away from the busbar.
