63A RCBO

63A RCBO Product Series FAQ

Is RCBO better than RCCB?

RCBO (Residual Current Circuit Breaker with Overcurrent Protection) combines both residual current (leakage) protection and overcurrent/short-circuit protection in one device, while RCCB (Residual Current Circuit Breaker) only protects against leakage currents. For circuits needing comprehensive safety—such as residential wiring, commercial outlets, or industrial machinery—RCBOs are more efficient, reducing the need for separate overcurrent breakers.

What is type a RCBO?

Type A RCBOs detect both sinusoidal alternating current (AC) leakage and pulsating direct current (DC) leakage (e.g., from electronic devices with rectifiers). This makes them ideal for modern circuits with variable-speed drives, LED lighting, or battery chargers, where DC leakage may occur alongside AC faults.

Why is my RCBO tripping?

Common reasons include:

• Overload: Current exceeding the rated 63A for prolonged periods.
• Short-circuit: Sudden high current due to faulty wiring or equipment.
• Leakage: Current flowing to ground (e.g., damaged insulation, wet environments).
• Faulty Appliances: A connected device with internal leakage.
• Aging: Wear from repeated tripping or long-term use.

63a rcbo price

63A RCBO prices vary based on factors like pole configuration (e.g., 1P+N, 2 pole, 4 pole), residual sensitivity (30mA, 100mA, 300mA), tripping characteristics (B/C/D), and additional features (e.g., accessory compatibility). For precise pricing, contact local distributors or manufacturers with your specific requirements (e.g., "63a rcbo 4 pole" or "63a rcbo 100ma").

What pole options are available for 63A RCBO?

63A RCBOs are offered in 1P+N (single-phase with neutral), 2 pole (double-pole), and 4 pole configurations. 4-pole models are ideal for 3-phase systems with neutral, while 2-pole (2P) or DP (double-pole) RCBOs provide balanced protection for 230V circuits.

What’s the difference between 63A RCBO 100mA and 30mA?

The "mA" refers to residual operating current (IΔn). 30mA models are highly sensitive for personal safety (e.g., preventing electric shock in residential areas), while 100mA versions are used for fire protection in less critical circuits (e.g., outdoor lighting, storage rooms).

Can 63A RCBO be used in industrial settings?

Yes! 63A RCBOs with type D tripping characteristics (10-20In) handle high inrush currents from motors or transformers, making them suitable for industrial machinery and workshop circuits.
