Residual Current Circuit Breaker (RCCB)

Microtek RCCB is one of our safety solution designed to protect the consumers from fatal electric shocks and prevent fire caused by earth faults. The RCCB is a mechanical switching device that carries and breaks current under normal service conditions and to causes the opening of the contacts when the leakage current attains a given value under specified conditions. The high quality insulation and wires adds to the safety of consumer.

FAQs

MCBs are electro-mechanically operated automatic circuit protection devices which are used to protect an electrical circuit from an over-current caused by overload or short circuit.

The miniature circuit breaker is a protection device that prevents damage to an equipment /circuit on the event of an overload or short circuit faults. During overload and short circuits excessive current flows to the load that may damage the equipment. Miniature circuit breakers sense such excessive currents and disconnect the load from the source, thus preventing greater damages to the circuit/appliances.

A MCB trips when any overcurrent flows through the connected circuits, it may be due to overload or short circuit. Higher the intensity of fault quicker shall be the MCB action.

No, You will need RCCB (Residual current circuit breaker) since it is especially meant to protect against electric shock hazards to humans. MCB is mainly used to protect your device from an overload current in case of some internal short circuit fault in your device.

Residual Current Circuit Breaker (RCCB) is a differential current sensing device used to protect a low voltage circuit in case of a leakage fault. It is sometimes also known as Residual Current Device (RCD). It contains a switch device that switches off (in a fraction of a second), whenever the current leaks out and does not return back through neutral. The RCCB provides protection from small current leakage arising due to accidental touch by human being or insulation failure, which is not possible by MCB or fuse alone.

The miniature circuit breaker is a protection device that prevents damage to an equipment /circuit on the event of an overload or short circuit faults. Residual current circuit breakers are devices that protect against electric shock. It senses earth leakages and residual currents and ensures protection against electric shock. RCCBs do not have overload and short circuit protection features built-in. Isolators are devices used to isolate a circuit or equipment from the power supply, they do not offer any kind of protection to the circuit or device.
