## Summary description

Three-pole (3P) Hager MBN310E miniature circuit breaker with B tripping characteristic, rated current 10 A and breaking capacity 6 kA (AC). Designed to protect electrical circuits from overloads and short circuits in three-phase installations. Suitable for distribution boards in residential and light commercial applications where coordinated overcurrent protection is required.

## Long description

Hager Circuit breaker 3P B 10A 6kA AC MBN310E is a three-pole miniature circuit breaker designed for protection of three-phase electrical circuits. It features a B-type tripping characteristic and a rated current of 10 A, with a breaking capacity of 6 kA (AC). The device is intended for installation in distribution boards in residential and light commercial environments where selective overcurrent protection and coordination between phases are required.
Advantages
The breaker provides reliable short-circuit and overload protection for three-phase circuits while maintaining compact dimensions suitable for standard DIN-rail mounting. Its B tripping characteristic ensures sensitivity to low fault currents typically found in residential and light commercial installations, helping to prevent nuisance trips while still providing fast disconnection for true faults. The 6 kA breaking capacity meets common distribution requirements and supports safe interruption of fault currents within its rated limits.
Suitable for
 Protection of three-phase branch circuits in residential electrical panels
 Small commercial installations and light industrial circuits with coordinated protection needs
 Motor control circuits and lighting circuits with moderate inrush currents
 Replacement or upgrade of existing three-pole miniature circuit breakers with similar characteristics
Key specifications
 Poles: 3-pole (three-phase)
 Tripping characteristic: B-type
 Rated current: 10 A
 Breaking capacity: 6 kA (AC)
 Mounting: DIN-rail compatible, compact miniature circuit breaker format
 Application: Overload and short-circuit protection for three-phase circuits
How to use
Install the breaker on a standard DIN rail inside a distribution board according to local electrical codes. Connect the three-phase supply and load conductors to the corresponding terminals, ensuring secure tightening of terminal screws and proper phase sequence. Verify the rated current and characteristic match the circuit requirements before energizing. After installation, switch the breaker to the ON position and perform an appropriate functional test of the protected circuit. Any wiring, installation, or maintenance work should be carried out by a qualified electrician.
Usage recommendations
Choose this three-pole B characteristic breaker where sensitivity to low-level faults and selective protection in residential or light commercial three-phase installations is required. Confirm system short-circuit levels do not exceed the 6 kA breaking capacity and coordinate upstream and downstream protective devices to ensure proper discrimination.
