China Residual Circuit Breaker with Overcurrent Protection Manufacturer, Supplier, Factory

Residual Circuit Breaker with Overcurrent Protection is widely used in various fields such as household, industrial and commercial, especially in situations where leakage and overcurrent protection are required at the same time. For example, in household circuits, RCBO can protect sockets, lighting circuits, etc. from leakage and overcurrent hazards; in industrial and commercial premises, RCBO can protect the safe operation of electrical equipment such as motors and distribution boxes.

What are the advantages and characteristics of Residual Circuit Breaker with Overcurrent Protection?

Double protection function: RCBO combines the functions of leakage protection and overcurrent protection, providing more comprehensive protection against electric shocks.

High sensitivity: RCBO's high sensitivity to detect residual current and overcurrent enables it to react quickly and disconnect the circuit.

Easy to install and maintain: RCBO has a compact structure, small size and is easy to install; at the same time, its internal components are carefully designed with a long service life and low failure rate.

Curve C RCBO

STR02-40 Curve C RCBO is mainly used in the circuit of AC50/60HZ two poles 230V or four poles 400V, rated current up to 6A-40A for effective overload and short-circuit protection and infrequent changeover of line under normal condition, as well as automatically and immediately cutting off the power supply once someone suffers from electric shock or leakage current exceeds specified value. It can effectively protect personal security and avoid the damages to the equipment. It is suitable for all kinds of places, such as industry, commerce, high rise and civil residence.

4P RCBO AC Type

The 4P RCBO AC Type is a 4-pole circuit breaker that combines residual current protection and overcurrent protection functions, especially designed for alternating current (AC) circuits. It can automatically cut off the power supply when residual current (i.e. leakage current) is detected in the circuit to prevent electrical fires and personal electric shock accidents. At the same time, it also has an overcurrent protection function that can automatically cut off the power supply in the event of an overload or short-circuit in the circuit to protect the safety of the circuit and equipment.

2P 1P+N Residual Circuit Breaker with Overcurrent Protection

The 2P 1P+N Residual Circuit Breaker with Overcurrent Protection is a circuit breaker that combines residual current protection and overcurrent protection. It is capable of automatically cutting off the power supply when residual current (i.e. leakage current) is detected in the circuit to prevent electrical fires and personal electrocution accidents. At the same time, it also has an overcurrent protection function, which can automatically cut off the power supply when the circuit is overloaded or short-circuited to protect the safety of the circuit and equipment.
