Etek AC 1P+N RCD 40A Type A-MV (Earth Leakage)

R470.35 incl Vat

Etek AC 1P+N RCD 40A Type A-MV (Earth Leakage)

EKL3-40M Electro type RCBO is mainly used for AC 50Hz or 60Hz, rated voltage 230 or below and rated working current 40A or below and immediately cut off power supply once someone suffers from electric shock or leakage current above specified value. The circuit-breaker can also function as overload and short-circuit protection and unfrequented changeover of line under normal condition.

RCBO (Residual Current Circuit Breakers with Overcurrent Protection)

A Residual Current Circuit Breaker (RCCB)

RCD (Residual Current Device)

What is a RCBO used for?

RCBOs are commonly used in applications where there is the need to combine protection against overcurrents (overload and short-circuit) and protection against earth leakage currents. RCBOs help in sensing this kind of faults and trip the circuit ensuring complete protection of the people and connected equipment.

What is the difference between a RCD and RCBO?

An RCD is a protective device that will protect a number of circuits, normally at least 5. If it picks up a fault on any of these circuits it will trip cutting the power to every circuit it is protecting. An RCBO is basically exactly the same as an RCD however it protects 1 individual circuit.

Is a RCBO better than a RCD?

RCD Vs. RCBO: What is the Difference? RCDs can protect against electric shocks, residual currents, and earth faults. On the other hand, RCBOs can do what RCDs can do and protect a circuit from short circuits and overload.

When should a RCBO be used?

The primary functions of RCBOs are to ensure protection against earth fault currents, overload, and short circuit currents. It is recommended that an RCBO be attached to each separate circuit, meaning that a fault in one circuit will not affect the functioning of the others.

Can I replace RCD with RCBO?

However, you can meet these specifications and save space on the circuit breaker panel: on some circuits, you can replace two devices (RCD and circuit breaker) with a single device (RCBO). This will protect these circuits against current leaks and overloads at the same time.

Does RCBO replace MCB?

Yes you can use RCBO as a replacement to MCB and RCB. In general, RCBO is basically circuit breaker in addition to residual current device. It provides over current, short circuit as well as earth leakage protection.

What is better to use for home wiring RCCB or RCBO and why?

Installation of RCBO is easier than RCCB. RCBO is designed to optimize the operation, facilitate troubleshooting and reduce inefficiencies and downtime.

How can you tell the difference between a RCCB and RCBO?

RCCB will only identify current leakage from circuit. On the other hand, RCBO can notice over current and current leakage from the circuit. The device recognizes over current in the same manner as MCB does. RCBO is usually utilized as replacement for MCB in consumer unit.
