CHINT NM8NSD – Moulded-Case Circuit Breaker with Integrated Earth Leakage Protection

The CHINT NM8NSD series is a premium moulded-case circuit breaker (MCCB) equipped with integrated earth leakage protection, offering advanced safety and reliability for modern electrical distribution systems. Designed for both commercial and industrial environments, the NM8NSD provides effective protection against overloads, short circuits and residual-current faults, ensuring enhanced safety and compliance in critical installations.

Key Features

• Integrated residual-current (earth leakage) protection for enhanced electrical safety.
• Moulded-case design with high mechanical strength and long service life.
• Accurate thermal-magnetic trip characteristics for reliable overload and fault protection.
• Adjustable leakage sensitivity and trip settings depending on model configuration.
• Compact design suitable for modern distribution boards and industrial panels.
• Clear ON/OFF/trip status indicators for improved visibility and safety.

Typical Applications

• Main and sub-distribution panels in commercial buildings.
• Industrial electrical systems requiring combined MCCB and leakage protection.
• Solar, hybrid and energy-storage AC distribution panels.
• Workshops, factories and plant environments with higher electrical safety requirements.
• Backup systems, generator boards and critical-load protection.

Installation Notes

• Install in a compliant enclosure with adequate ventilation and clearance.
• Ensure cable size, terminals and lugs are matched appropriately to the breaker rating.
• Follow manufacturer torque and wiring guidelines for optimal performance.
• Regularly test leakage functionality as required by local electrical standards.

The NM8NSD series offers high-performance protection and integrated earth-leakage functionality, making it an excellent choice for installers seeking reliability, safety and flexibility in a single MCCB solution.
