Effectively protect your electrical circuits from overcurrents and power spikes with this miniature circuit breaker from ABB. It's a 2-pole switch with a curve C tripping characteristic, which means the unit will trip when it reaches between 5 and 10 times the rated current. The device has two different tripping mechanisms – thermal and electromechanical – to safeguard your systems against both overloads and short circuits. You can connect a bottom-fitting auxiliary contact to the unit and save up to 50% mounting space.

• DIN rail mounting capability for neat and space-saving installations
• IP20 (ingress protection) rating indicates the unit is touch-proof to prevent electric shocks and enhance safety
• Wide operating temperature range from -25°C to +55°C for use in heavy-duty applications

• Electric motors
• Lighting applications
• Heating, ventilation and air conditioning systems

A curve C tripping characteristic means the MCB will immediately trip at a rate of five to 10 times its rated current. The tripping characteristic indicates what electrical or current loads a device can handle.
