## Summary description

Miniature circuit breaker by noark with 6 kA breaking capacity, B tripping characteristic and rated current 50 A in a 3-pole configuration. Designed to protect electrical circuits from overloads and short circuits, it suits residential, commercial and light industrial distribution boards. Compatible with standard DIN-rail mounting for reliable circuit protection.

## Long description

Miniature circuit breaker noark 6 kA B curve 50 A 3-pole is a compact overcurrent protection device designed for installation in residential, commercial and light industrial distribution boards. It provides thermal-magnetic protection against overloads and short circuits with a B tripping characteristic suitable for circuits with mainly resistive loads. The device is built for DIN-rail mounting and offers a clear three-pole switching solution for three-phase circuits, helping to isolate and protect conductors from fault currents up to 6 kA.
Advantages
The noark 3-pole miniature circuit breaker combines a B curve trip unit with a 50 A rated current and a 6 kA breaking capacity, creating a balance between sensitivity to small overloads and reliable interruption of short-circuit currents. Its compact footprint and DIN-rail compatibility simplify installation and integration into standard distribution enclosures. The three-pole design ensures simultaneous disconnection of all phases for safer maintenance and fault clearing.
Suitable for
 Protection of three-phase branch circuits in homes and small commercial units
 Feeding motors and resistive loads with low inrush currents
 Use in distribution boards and consumer units with DIN-rail mounting
 Overload and short-circuit protection in light industrial installations
Key specifications
 Rated current: 50 A
 Poles: 3-pole (three-phase)
 Tripping characteristic: B curve (thermal-magnetic)
 Breaking capacity: 6 kA
 Mounting: standard DIN-rail compatible
 Function: combined overload and short-circuit protection
How to use
Install the miniature circuit breaker on a standard DIN-rail inside a suitable distribution board, following local wiring regulations and safety standards. Connect the three phase conductors to the input terminals and the load conductors to the output terminals, ensuring appropriate torque on terminal screws and correct conductor sizing for a 50 A rated device. After installation, verify correct operation by switching the breaker on and off; testing under simulated fault conditions should be performed only by qualified personnel.
Usage recommendations
Choose this B curve 50 A breaker when protecting circuits with primarily resistive loads or small motor loads with low starting currents. Ensure coordination with upstream and downstream protective devices to achieve selective tripping and prevent nuisance trips. Periodically inspect connections and the breaker condition, and replace if signs of damage, overheating or repeated nuisance trips are observed.
