Johdonsuojakatkaisija Hager MBN110 1P, 10 A, 50–60 Hz

Hager MBN110 is a single-pole miniature circuit breaker rated for 10 A with an AC frequency range of 50–60 Hz. Intended for DIN-rail installation in residential and light commercial distribution boards, this device provides overcurrent and short-circuit protection for single-phase circuits. The compact design and standard mounting dimensions allow integration into modular switchboards and consumer units where space and reliable circuit protection are required.

Advantages

The single-pole configuration minimizes space usage while offering reliable thermal-magnetic protection for conductors and connected equipment. The 10 A nominal current is suitable for protecting lighting circuits, small appliances, and branch circuits. Compatibility with standard DIN-rail systems ensures straightforward installation and replacement. The device is designed for stable operation in networks with an AC frequency of 50–60 Hz and conforms to typical safety and mounting requirements for miniature circuit breakers.

Key specifications

How to use

Mount the circuit breaker on a compatible 35 mm DIN-rail inside the distribution board, ensuring the device is oriented according to the manufacturer's installation guidelines. Connect the line conductor to the input terminal and the load conductor to the output terminal, making sure conductors and terminals are tightened to the recommended torque. After installation, switch the breaker to the ON position and verify circuit continuity and correct operation by applying a controlled load or performing standard electrical tests compatible with local regulations.

Recommendations

Use the breaker only within its specified current and frequency ratings. Ensure upstream and downstream protective devices and wiring are chosen to match the 10 A rating and that installation is performed by a qualified person following applicable electrical codes. Periodically inspect terminals for secure connections and signs of overheating; replace the device if it shows physical damage or fails routine operational checks.
