Maasarent MCBTPN-B063 Triple Pole + Neutral Miniature Circuit Breaker (TPN MCB) B Curve 63A

Long Description

The MCBTPN-B063 Triple Pole + Neutral Miniature Circuit Breaker (TPN MCB) is designed to deliver safe, reliable, and efficient protection for three-phase electrical distribution systems where neutral switching is required. With a B Curve tripping characteristic, it is suitable for circuits with low inrush currents such as lighting systems, general power distribution, residential complexes, commercial buildings, and office installations.

This device ensures simultaneous protection and disconnection of three phases along with the neutral conductor, providing complete circuit isolation during fault conditions or maintenance activities. Its thermal-magnetic trip mechanism delivers accurate overload detection and rapid response to short-circuit faults, ensuring system safety and protecting connected equipment.

Manufactured using high-quality flame-retardant engineering plastic, the MCBTPN-B063 offers durability, long service life, and consistent performance under continuous electrical load conditions. Its compact DIN rail mounting design enables easy installation in distribution boards and control panels, while finger-safe terminals improve safety during wiring and maintenance operations.

The TPN configuration makes it especially suitable for installations requiring neutral switching along with phase protection, enhancing safety in modern three-phase distribution systems.
