Brand: Chint

Product Description

The CHINT NXBLE-63 4-Pole Residual Current Circuit Breaker (RCBO) is designed to provide combined earth leakage, overload and short-circuit protection in three-phase electrical installations.

Combining residual current protection with thermal-magnetic overcurrent protection in one compact device, the NXBLE-63 helps protect electrical circuits, equipment and installations against electrical faults.

With a four-pole configuration, this RCBO is designed for suitable three-phase applications requiring switching and protection across four conductors. Its rated operating voltage is 400V AC, with current ratings ranging from 6A to 63A.

The NXBLE-63 is suitable for commercial buildings, industrial distribution boards, electrical control panels and three-phase power distribution systems.

Applications

Three-phase electrical distribution boards.
Commercial buildings.
Industrial electrical panels.
Three-phase machinery and equipment.
Commercial power distribution systems.
Industrial control panels.
Three-phase circuits requiring residual current protection.
Electrical installations requiring combined earth leakage and overcurrent protection.

Installation and Safety

Installation must be performed by a qualified electrician.
Confirm the rated current and voltage before installation.
Select the appropriate residual current sensitivity.
Verify the correct B, C or D tripping characteristic.
Follow the manufacturer’s terminal connection diagram.
Confirm the neutral and phase conductor arrangement.
Ensure proper protective earthing.
Test the device according to the manufacturer’s instructions.
Isolate all electrical supplies before installation or maintenance.

Important: An RCBO does not replace the protective earthing system. Correct earthing, wiring and circuit coordination are essential for safe operation.
