Main features and parameters

Action Characteristics: 2P 4P RCBO B Type has a residual current protection function, when the residual current (i.e. leakage current) in the circuit reaches a preset value, the circuit breaker will act quickly to cut off the circuit to prevent electric shock accidents and electrical fires.

Rated Current: Depending on the specific model and specifications, the rated current range of 2P 4P RCBO B Type may vary, but usually includes a wide range of specifications such as 6A, 10A, 16A, 20A, 25A, 32A, 40A, 50A, 63A, 80A,and so on.

Rated Voltage: The 2P 4P RCBO B Type is typically rated at 240V AC for domestic and commercial electrical environments.

Rated Frequency: The rated frequency of this circuit breaker is usually 50/60Hz, which matches the frequency of power supply in most countries and regions.

Rated Short Circuit Capacity: The 2P 4P RCBO B Type has a high rated short circuit capacity, such as 6KA or 10KA, which is able to withstand large current shocks without damage in the event of a short circuit fault.

Leakage Action Current: The leakage action current of this circuit breaker is usually 30mA or less, which meets the requirements of the International Electrotechnical Commission (IEC) and relevant national standards, and can effectively protect personal safety.

RCBO is mainly used in AC 50Hz(60Hz), rated voltage 230/400V, rated current 6A to 40A low voltage terminal distribution system. RCBO is equal with MCB+RCD function; It is used for electric shock protection and human indirect contact protection, electric equipment protection when human body touching electricity or electric network leak current exceeds stipulated value,and over load and short circuit protection ; It can also be a non-frequency operator in the circuit, wildly used in the residential and commercial district. It complies with standard of IEC61009-1.

Application and Installation

Application: 2P 4P RCBO B Type is suitable for the protection of power distribution circuits that require simultaneous control of both Fire and Zero wires, such as lighting, sockets, air-conditioning and other circuits in domestic, commercial, industrial and other places.

Installation: The circuit breaker usually adopts symmetrical DIN-rail mounting or panel mounting, which is convenient for quick installation and removal in distribution box or distribution cabinet.

Wiring:2P 4P RCBO B Type is flexible in wiring and can be connected to three-phase three-wire, three-phase four-wire or single-phase circuits. When wiring, ensure that the Fire, Zero and Earth wires are properly connected to avoid the risk of electric shock and electrical fire.
