Products RCBO Residual Current AC Breaker with Overcurrent Protection 2p 4p 3p+N

Product Description

Product Description

 

The Residual Current Breaker with Over-Current protection (RCBO) is an essential safety device ingeniously crafted for electrical systems. It seamlessly integrates the functions of a Residual Current Device (RCD) and a Mini Circuit Breaker (MCB). This dual-purpose marvel is engineered to offer paramount protection to both individuals and equipment by adeptly detecting residual currents (leakage currents) alongside over-currents (overloads and short circuits). Widely deployed in residential, commercial, and industrial environments, it significantly elevates the safety and dependability of electrical installations.

Residual Current Protection

An RCBO exhibits relentless vigilance by continuously monitoring the current traversing through the live (hot) and neutral wires of a circuit. Under normal operating conditions, the currents in both wires maintain equilibrium. Yet, should a leakage current arise-perhaps due to a defective appliance or current inadvertently finding its path to the ground via a person-the RCBO swiftly detects this imbalance. It then acts decisively by tripping, thereby disconnecting the circuit and safeguarding against potential electric shocks.

Product Benefits :

• Air circulation

Ingeniously designed, when two poles are positioned next to one another, these channels ingeniously form a tunnel, ensuring optimal air circulation around each individual pole.

• Bi-connect Termination Possible

Offers the versatile option to employ both Busbar and/or cable within the same terminal, guaranteeing a robust and reliable termination.

• Din Rail Mounting

Equipped with a two-step snapping mechanism, it promises effortless and efficient mounting on a 35mm DIN Rail, ensuring steadfast stability.

Residual current-operated circuit breakers (RCBO) with advanced overcurrent protection are exceptionally suited for scenarios demanding both overcurrent protection (encompassing overload and short circuit) and ground-fault current protection. With a keen ability to swiftly detect faults and initiate timely tripping, it ensures the utmost safety of personnel and equipment. Its applications span across energy management systems, power supply, and distribution network automation, residential power monitoring, and comprehensive sets of equipment.
