Overcurrent circuit breaker, 6kA, B characteristic, 3-pole, 32A MBN332E

Overcurrent circuit breaker – reliable installation protection

The Hager MBN332E overcurrent circuit breaker is a three-pole (3P) device designed to protect electrical circuits from the effects of overloads and short circuits. A rated current of 32A combined with characteristic B makes it an ideal solution for both home and professional installations. The short-circuit breaking capacity of 6kA (according to IEC 60898-1) ensures effective protection even in the event of serious disturbances.

Features and application

The MBN332E circuit breaker is used to protect lighting circuits, socket outlets and other electrical devices with moderate power requirements. Characteristic B means that the circuit breaker reacts quickly to short circuits, but is more tolerant to short-term current surges, which is particularly important when connecting devices with electric motors (e.g. refrigerators, washing machines). The three-pole design provides complete protection in three-phase installations.

• Overload protection: Protects the circuit from damage caused by excessive current draw.
• Short-circuit protection: Immediately interrupts the circuit in the event of a short circuit, minimizing the risk of fire and equipment damage.
• Characteristic B: Ideal for protecting lighting circuits and general-purpose sockets.
• Three-pole design (3P): Provides complete protection in three-phase installations.
• Short-circuit breaking capacity 6kA: Effective protection even in the event of serious disturbances.
• DIN rail mounting: Standard mounting simplifies installation and replacement of the circuit breaker.

Construction and parameters

The MBN332E circuit breaker is characterized by a solid construction and high quality workmanship, which guarantees reliable operation for a long time. It has 3 modules wide, allowing for easy adaptation to the existing distribution board. Screw terminals provide a secure connection of wires with a cross-section from 1 mm² to 35 mm². In addition, the circuit breaker meets high safety standards and has appropriate certificates.

This circuit breaker has a rated current of 32A and is characterized by a tripping characteristic B. Its rated short-circuit breaking capacity (Icn) is 6kA, and its rated ultimate short-circuit breaking capacity (Icu) is 10kA. The device is three-pole (has 3 poles), occupies 3 modules wide and is designed to operate at a rated voltage of 400V. It also has a protection degree of IP20 and can operate at a temperature from -25°C to +70°C.

The Hager MBN332E circuit breaker is an investment in the safety and reliability of your electrical installation. Solid construction, high quality and compliance with standards ensure peace of mind and long-term protection against the effects of overloads and short circuits.
