Need protection against short-circuit currents and overload currents? Schneider Electric's miniature circuit breaker (MCB) provides just that. It has a 4A current rating and a Type C tripping curve, meaning it trips at 5 to 10 times the rated current. This makes it suitable for high-power devices where substantial surges can be expected. This MCB safeguards users against indirect contact with TN (transformer neutral) and IT (unearthed transformer neutral) systems by cutting power when a fault occurs between a live part and an external conducting element.

• DIN rail mounting style for easy and time-efficient installation and removal
• VisiSafe green strip indicates the safe position of contacts, providing protection during maintenance work on downstream currents
• VisiTrip technology gives a visual indication that the circuit has tripped, for quick fault detection and resolution and fast reclosing of loads

• Domestic circuits
• Fluorescent lighting
• Small transformers, pilot devices and coils

Padlocking the MCB prevents the circuit from being accidentally or deliberately switched on or off. Locking the MCB in an off position helps protect those working on a circuit, as no one can inadvertently turn the circuit on while work is being carried out.
