Maasarent MCBFP-B040 40A Single Pole B Curve Miniature Circuit Breaker (MCB)

Long Description

The MCBFP-B040 40A Single Pole B Curve Miniature Circuit Breaker (MCB) is a high-quality electrical protection device engineered to safeguard low-voltage electrical circuits from overloads and short-circuit faults. Featuring a 40A rated current and a B Curve tripping characteristic, it is ideal for circuits with low inrush currents, such as lighting, socket outlets, and general household electrical loads.

Designed to trip automatically during abnormal current conditions, the MCBFP-B040 helps prevent damage to wiring, appliances, and electrical equipment while reducing the risk of electrical fires. Manufactured using premium flame-retardant thermoplastic materials, it offers excellent durability, long service life, and reliable performance in demanding environments.

Its compact DIN rail-mounted construction allows for quick installation in distribution boards, switchgear, and electrical control panels, making it a preferred choice for electricians, contractors, and electrical system integrators.

Whether used in residential homes, commercial offices, retail outlets, or industrial facilities, the MCBFP-B040 delivers dependable protection and supports safe, efficient power distribution.
