Maasarent MCBTPN-C040 Triple Pole + Neutral Miniature Circuit Breaker (TPN MCB) C Curve 40A

Long Description

The MCBTPN-C040 Triple Pole + Neutral Miniature Circuit Breaker (TPN MCB) is designed for safe, reliable, and efficient protection of three-phase electrical distribution systems where neutral switching is required. With a C Curve tripping characteristic, it is suitable for circuits with moderate inrush currents such as motors, pumps, compressors, HVAC systems, transformers, and general industrial and commercial loads.

This device provides simultaneous protection and disconnection of three phases along with the neutral conductor, ensuring complete isolation during fault conditions and maintenance operations. Its thermal-magnetic trip mechanism ensures accurate overload detection and rapid interruption of short-circuit faults, improving system reliability and protecting connected equipment.

Manufactured using high-quality flame-retardant engineering plastic, the MCBTPN-C040 offers durability, long service life, and consistent performance under demanding electrical conditions. The compact DIN rail mounting design allows easy installation in distribution boards and control panels, while finger-safe terminals improve installation safety and handling efficiency.

The TPN configuration makes it suitable for modern installations where both phase and neutral isolation are required, enhancing operational safety in three-phase electrical distribution systems.
