FuseBox MT06B201 20A Type B MCB

The FuseBox MT06B201 is a 20A Type B single-pole miniature circuit breaker (MCB) designed to provide reliable protection against overloads and short circuits in electrical installations. Installed within consumer units or distribution boards, it automatically disconnects the circuit when abnormal current levels are detected, helping protect wiring and connected equipment.

Featuring a Type B tripping curve, this breaker is suitable for domestic and light commercial circuits such as socket outlets, lighting, and general-purpose electrical loads where moderate inrush currents may occur. The device offers a 6 kA short-circuit breaking capacity, ensuring dependable protection for modern electrical systems.

Its compact single-module design allows easy installation in FuseBox consumer units and other compatible DIN-rail distribution boards. The integrated thermal-magnetic trip mechanism provides both overload and short-circuit protection for safe and consistent circuit operation.
