Overcurrent circuit breaker, 6kA, B characteristic, 1-pole, 50A MBN150E

Overcurrent circuit breaker – reliable protection for installations

This single-pole overcurrent circuit breaker from Hager, with a rated current of 50A and B characteristic, is a key element of every safe electrical installation. It provides effective protection against the effects of overloads and short circuits, minimizing the risk of damage to equipment and fires. It is an indispensable component for both professional installers and end-users who care about safety in their home or business.

Functionality and technical parameters

The MBN150E circuit breaker has been designed for reliability and ease of installation. Its compact dimensions (1 module width, 70 mm depth) allow for optimal use of space in the distribution board. The rated short-circuit breaking capacity Icn is 6kA at 230V, and Icu at 230V reaches 10kA, guaranteeing a quick response in emergency situations. The B characteristic means that the circuit breaker reacts quickly to overloads, but is more tolerant of short-term current surges – which is particularly important when connecting devices with electric motors or other elements generating inrush current. Suitable for operation in a temperature range from -25°C to 70°C, it will perform well in various environmental conditions.

Installation and compatibility

The MBN150E circuit breaker offers a wide range of conductor connections – from 1 to 35 mm² for solid conductors and from 1 to 25 mm² for stranded conductors. Flush mounting facilitates aesthetic integration into the surroundings. Compliance with IEC 60898-1 and IEC 60947-2 standards ensures a high level of safety and reliability. The IP20 degree of protection protects against finger contact, but does not provide protection against water ingress. Made of high-quality materials, it guarantees long-lasting and trouble-free operation.
