This 16A, C-curve, DIN rail mounted Miniature Circuit Breaker (MCB) protects an electrical circuit from damage caused by excess current from an overload or short circuit.
This MCB is double pole meaning that it will provide overload and short circuit protection on the live & neutral wires and will disconnect both circuits under fault conditions, even in the case of a polarity-reversed site supply.
Note: If you are unsure whether this product is suitable for your application, please consult a qualified electrician.
