Product Description

The CHINT NXB-63 1P C4A is a compact, reliable miniature circuit breaker from the popular NXB-63 series, designed for final circuit protection in residential, commercial, and light industrial applications. With C-curve tripping (suitable for general-purpose loads with moderate inrush currents such as lighting, small control circuits, electronics, and resistive loads), it provides overload and short-circuit protection in single-phase systems. The 4 A rating is commonly used for low-power branches (e.g., LED lighting, control transformers, small appliances, or instrumentation circuits). The 1-module width makes it easy to install in standard consumer units and distribution boards.

Standard Features

  • 4 A C-curve rating: Ideal for low-current circuits — trips at 5–10 times rated current for balanced protection.

  • 6 kA breaking capacity: Handles typical faults in domestic and light commercial installations.

  • 1-pole design: Protects single-phase live conductor — standard for lighting and socket circuits.

  • Thermal-magnetic protection: Overload (thermal) + short-circuit (magnetic) disconnection for full safety.

  • Compact 1-module width: 18 mm wide — fits standard DIN-rail consumer units and modular panels.

  • Global compliance: IEC/EN 60898-1 certified, CE marked — widely accepted for final distribution.
