Chint NXM-630S 3P 500A MCCB in Pakistan

Chint NXM-630S 3P 500A MCCB is a high-performance Moulded Case Circuit Breaker designed to deliver robust circuit protection and isolation for main power distribution systems, industrial control panels, and commercial electrical infrastructure. Engineered to operate efficiently under demanding electrical environments, the NXM series combines compact dimensions with high switching power to keep your machinery and networks safe from electrical faults.   

Key Features & Technical Capabilities

• Robust Fault Protection: Built with a standard ‘S’ breaking capacity level, delivering up to 50kA breaking performance at 400V/415V AC to mitigate high short-circuit currents and prevent catastrophic panel damage.

• Thermal-Magnetic Release: Features fixed thermal-magnetic trip units that provide dependable inverse time-delay protection against continuous overloads, alongside instantaneous magnetic tripping during short circuits.

• Flexible Installation: Accommodates both vertical and horizontal mounting configurations without performance derating, making it ideal for custom switchboards and distribution boards.   

• High Insulation Standards: Supports a rated insulation voltage (Ui​) of 800V and an impulse withstand voltage (Uimp​) of 8kV, offering enhanced protection against transient voltage spikes.   

  Applications

• Main low-voltage power distribution panels and switchgears   

• Motor control centers (MCC) and industrial machinery automation   

• Commercial building electrical mains and backup generator power switches

• Solar inverter output combining and sub-station protection
