## Summary description

Three-pole Hager MC320A miniature circuit breaker rated 20 A with C tripping characteristic and 6 kA short-circuit breaking capacity. Designed for DIN-rail mounting in electrical distribution boards to protect circuits against overloads and short circuits. Suitable for residential, commercial and light industrial installations where selective tripping and moderate inrush tolerance are required.

## Long description

The Hager MC320A is a three-pole miniature circuit breaker rated at 20 A with a C tripping characteristic and a 6 kA short-circuit breaking capacity. It is designed for DIN-rail mounting in distribution boards and provides overcurrent protection for three-phase circuits. The device combines a compact form factor with standard thermal-magnetic trip behavior to protect conductors and equipment from overloads and short circuits while allowing moderate inrush currents typical of motors and lighting loads.
Advantages
The three-pole configuration ensures simultaneous disconnection of all phases, reducing the risk of phase imbalance and equipment damage. The C characteristic offers a balance between sensitivity to overloads and tolerance of short-duration inrush currents, making it suitable where selective tripping is required. The 6 kA breaking capacity meets common installation requirements for residential and light commercial switchboards, and the DIN-rail design simplifies installation and replacement.
Suitable for
Protection of three-phase circuits in residential distribution boards
Lighting circuits and motor loads with moderate inrush currents
Small commercial or light industrial installations requiring coordinated protection
Retrofit or new installations using standard DIN-rail enclosures
Key specifications
Poles: 3-pole (three-phase)
Rated current: 20 A
Tripping characteristic: C
Short-circuit breaking capacity: 6 kA
Mounting: DIN-rail compatible
Function: Thermal-magnetic overcurrent protection
How to use
Mount the circuit breaker on a standard DIN-rail inside the distribution board and connect the incoming supply and outgoing load conductors to the appropriate terminals for the three phases and neutral if required. Ensure that conductors and terminal tightening torques follow local electrical regulations and manufacturer's installation instructions. Test the installation by switching the breaker on and off; verify that protective coordination with upstream and downstream devices is correct before placing circuits into regular service.
Usage recommendations
Choose this C-characteristic, 20 A, three-pole breaker where moderate inrush tolerance and coordinated protection are needed. Confirm that the 6 kA breaking capacity is adequate for the installation fault level and coordinate with upstream protective devices for selective tripping.
