Why Choose the CHINT NM1T-200/3N Enclosed MCCB with Neutral Link?
The CHINT NM1T-200/3N is a complete 200 A three-pole enclosed moulded case circuit breaker with neutral link, designed for low-voltage commercial and industrial power distribution. It combines a CHINT NM1 series MCCB with a dedicated enclosure and neutral connection, providing a practical solution for three-phase, four-wire electrical systems.
Rated at 200 A, the three-pole MCCB provides protection for the phase conductors against overload and short-circuit conditions. The NM1 MCCB platform is designed in accordance with IEC/EN 60947-2, while the NM1T enclosed range provides a convenient installation format for incoming, outgoing and local distribution circuits.
The NM1T-200/3N includes an isolating neutral link and is housed in an enclosure measuring approximately 600 mm high, 400 mm wide and 260 mm deep. Additional practical features of the NM1T enclosed range include a removable bottom gland plate and the ability to padlock the MCCB in the OFF position, supporting safe installation and maintenance practices.

Reliable 200 A Protection for Three-Phase Distribution
Moulded case circuit breakers are designed for higher-current electrical circuits where dependable protection against overload and short-circuit faults is required. The 200 A three-pole MCCB in the NM1T-200/3N protects and switches the three phase conductors, making the assembly suitable for distribution feeders, industrial equipment supplies and other compatible three-phase loads.
For three-phase, four-wire systems, the separate neutral link provides the required neutral connection without adding a fourth protected MCCB pole. Combined with the enclosure, removable gland plate and padlockable isolation facility, the NM1T-200/3N provides a practical packaged solution for commercial and industrial electrical distribution.
Typical Applications
- Three-phase commercial and industrial distribution systems.
- Incoming and outgoing electrical distribution feeders.
- Industrial machinery and equipment supplies.
- Switchboard and panel distribution circuits.
- Local isolation and circuit protection.
- Three-phase, four-wire systems requiring a neutral link.
- Commercial building electrical distribution.
