Overcurrent circuit breaker, 6kA, B characteristic, 1-pole, 40A MBN140E

Overcurrent circuit breaker – reliable installation protection

This single-pole overcurrent circuit breaker from Hager, with a rated current of 40A and a short-circuit breaking capacity of 6kA, is a key element in protecting electrical circuits. Designed for use in both domestic and industrial installations, it provides effective protection against the effects of overloads and short circuits. Characteristic B makes it ideal for circuits with receivers with low inrush currents, such as lighting or sockets.

Construction and application

The MBN140E circuit breaker is mounted on a DIN rail and occupies 1 module width. Its compact dimensions (70 mm depth) allow for easy installation even in limited space in the distribution box. The rated insulation voltage Ui is 500V, and the rated voltage is 400V, which guarantees safe use in standard installations. This circuit breaker protects against damage to wires and electrical equipment, ensuring continuity of supply and minimizing the risk of failure. The short-circuit capacity Icu at 10kA at 230V further increases the level of safety.

Key features and benefits

• Characteristic B: Provides a quick response to overloads, protecting sensitive electronic devices.
• Short-circuit breaking capacity 6kA: Effectively interrupts the circuit in the event of a short circuit, minimizing the risk of fire and equipment damage.
• DIN rail mounting: Enables easy and quick installation and replacement of the circuit breaker.
• Compact dimensions: Allow for saving space in the distribution box.
• Wide range of connectable conductors: Supports solid conductors with a cross-section from 1 to 35 mm² and stranded conductors from 1 to 25 mm².
• Protection degree IP20: Provides protection against accidental contact.
• Compliance with EN 60898-1 standards: Guarantee of safety and reliability confirmed by a certificate.
• Operating temperature from -25°C to 70°C: Possibility of use in difficult environmental conditions.

Thanks to these features, the Hager MBN140E circuit breaker is a reliable solution for every installer and end user looking for effective protection of their electrical installation.
