Hager MBN310E Miniature Circuit Breaker 6kA, B Curve, 10A, 3-Pole

The Hager MBN310E is a high-quality miniature circuit breaker (MCB) designed for reliable overcurrent protection in residential and commercial electrical installations. With a rated breaking capacity of 6 kA and a B tripping curve, it ensures safe disconnection of circuits in the event of overloads or short circuits. This 3-pole MCB is rated at 10 A and complies with EN 60898-1 standards, making it suitable for a wide range of applications.

Advantages

This MCB offers robust protection with a compact design that fits standard DIN rail mounting. Its B curve characteristic is ideal for resistive and lighting loads, providing fast response to short circuits while allowing for normal inrush currents. The screw terminals accommodate conductors up to 25 mm² rigid or 16 mm² flexible, ensuring easy and secure wiring. With an electrical and mechanical endurance of 20,000 cycles, it delivers long-lasting performance.
