CHINT NXB-63G-2P-C – 2-Pole C-Curve Miniature Circuit Breaker

The CHINT NXB-63G-2P-C is a high-quality miniature circuit breaker designed for single-phase electrical systems that require dependable protection with C-curve tripping characteristics. Its 2-pole design provides full isolation of both live and neutral conductors, making it suitable for residential, commercial and light-industrial installations where inductive or mixed loads are present.

Key Features

• 2-pole disconnection for safe isolation of live and neutral conductors.
• C-curve tripping — ideal for circuits with moderate inrush currents (motors, pumps, inverter loads).
• Thermal-magnetic trip mechanism for accurate overload and short-circuit protection.
• Compact DIN-rail mounting for clean and fast installation.
• Durable housing designed for long-term reliability in demanding environments.
• Clear ON/OFF indication for improved safety and visibility.

Typical Applications

• Lighting, plugs and mixed-load circuits.
• Single-phase pumps, fans and small motors with inrush current.
• Inverter AC output distribution in solar and backup systems.
• Residential and commercial DB boards.
• Workshops, retail installations and auxiliary circuits.

Installation Notes

• Mount on a standard 35 mm DIN rail inside an approved enclosure.
• Ensure correct orientation when wiring (line and load as marked).
• Use correctly sized conductors and follow torque specifications.
• Coordinate with upstream and downstream protection devices for selectivity.

The NXB-63G-2P-C offers reliable, professional-grade protection for single-phase circuits that require the dependable performance of a C-curve breaker—making it a trusted choice for electricians, installers and solar professionals.
