FAQs

What does the NXBLE-63 RCBO protect against?

The NXBLE-63 provides comprehensive protection by combining the functions of an MCB (overload/short-circuit) and an RCCB (earth leakage protection) in a single device.

In what applications can the NXBLE-63 be used?

It is suitable for residential, commercial, and industrial installations, including power distribution panels, lighting systems, and equipment requiring leakage protection.

How do the B and C tripping curves differ?

B Curve (3–5 In): For resistive loads like lighting or heating.

C Curve (5–10 In): For inductive loads such as motors or compressors.

What are the rated residual operating current options?

Available in 30mA, 100mA, and 300mA, offering tailored protection levels — from personal safety (30mA) to equipment and fire prevention (300mA).

How long is its operational lifespan?

The NXBLE-63 is engineered for over 20,000 mechanical and 4,000 electrical operations, ensuring long-lasting performance and minimal maintenance.
