CHINT NB1-63H-2P-C – 2-Pole C-Curve Miniature Circuit Breaker

The CHINT NB1-63H-2P-C is a compact, high-quality miniature circuit breaker designed for single-phase electrical systems requiring reliable C-curve protection. With its 2-pole configuration, it isolates both the live and neutral conductors, offering enhanced safety for residential, commercial and light-industrial installations.

Key Features

• 2-pole isolation for safe disconnection of live and neutral conductors.
• C-curve tripping – suitable for loads with moderate inrush current such as pumps, motors and inverter systems.
• Thermal-magnetic trip mechanism for accurate overload and short-circuit protection.
• Compact DIN-rail mounting for fast, clean installation.
• Durable housing designed for long-term reliability in demanding environments.
• Clear ON/OFF indication for improved safety and ease of use.

Typical Applications

• Lighting, plug circuits and mixed-load single-phase circuits.
• Small motors, pumps, fans and equipment with moderate starting current.
• AC distribution for solar inverter and backup power systems.
• Residential and commercial distribution boards.
• Workshops, retail spaces and auxiliary circuits.

Installation Notes

• Mount on a standard 35 mm DIN rail inside an approved enclosure.
• Follow correct wiring orientation according to breaker markings.
• Use properly sized conductors and torque settings as per manufacturer guidelines.
• Coordinate with upstream and downstream protection devices for selectivity.

The CHINT NB1-63H-2P-C delivers dependable C-curve protection with full 2-pole isolation, making it an excellent choice for professional electricians, solar installers and system integrators.
