Overcurrent circuit breaker, 6kA, B characteristic, 1-pole, 25A MBN125E

Overcurrent circuit breaker – reliable protection for your installation

This single-pole overcurrent circuit breaker from Hager, with a rated current of 25A and B characteristic, is a key element ensuring safety in every electrical installation. It provides effective protection against the effects of overloads and short circuits, protecting both devices and users. It is a universal solution, suitable for both residential and commercial buildings.

Product features and application

The MBN125E circuit breaker is characterized by a fast reaction to current changes, allowing for immediate disconnection of the circuit in case of a failure. The B characteristic makes it particularly recommended for protecting circuits with devices with low starting current, such as lighting or sockets. The rated short-circuit breaking capacity of 6kA guarantees effective protection even in the event of serious disturbances. Mounting on a DIN rail is simple and quick, making installation and servicing easier.

• Rated current: 25A – optimal for most standard circuits.
• Characteristic B: ideal for circuits with low starting currents.
• Short-circuit breaking capacity (Icn): 6kA – high effectiveness in case of short circuits.
• Rated voltage: 400V – compatible with most AC installations.
• Mounting: DIN rail – standard mounting for easy installation.
• Protection degree (IP): IP20 – protection against finger contact.

Construction and technical parameters

The circuit breaker is made of high-quality materials, ensuring its durability and reliability. Compact dimensions (70 mm depth, 83 mm height, 17.5 mm width) allow for easy placement in a distribution box. It meets the requirements of EN 60898-1 and IEC 60947-2 standards, confirming its safety and compliance with applicable regulations. The cross-section of the connectable single-wire conductor is 1-35 mm², and the multi-wire conductor is 1-25 mm², providing great flexibility when connecting conductors of different thicknesses.
