Maasarent MCBDP-B040 Double Pole Miniature Circuit Breaker (DP MCB) B Curve 40A

Long Description

The MCBDP-B040 Double Pole Miniature Circuit Breaker (DP MCB) is engineered to ensure dependable protection against overload and short-circuit faults in low-voltage electrical installations. Featuring a B Curve tripping characteristic, this MCB is particularly suitable for circuits with low inrush currents such as lighting systems, residential power distribution, office installations, and general electrical loads.

The Double Pole design simultaneously disconnects both phase and neutral conductors, enhancing safety and providing complete circuit isolation during fault conditions or maintenance procedures. Equipped with a precision thermal-magnetic trip mechanism, the MCBDP-B040 delivers rapid fault detection and reliable interruption of abnormal currents.

Manufactured using high-quality flame-retardant materials and designed for DIN rail mounting, the MCBDP-B040 combines durability, safety, and ease of installation. Its compact construction, finger-safe terminals, and long operational life make it an excellent choice for modern distribution boards and electrical control panels.
