Description
The Hager NCN320A is a robust 20A 3-pole MCB (Miniature Circuit Breaker) designed for reliable protection of three-phase electrical installations in commercial, light industrial, and high-demand environments. It safeguards equipment and wiring from both overloads and short circuits, providing dependable performance where safety is critical.
This breaker uses a C curve tripping characteristic, which activates between 5 to 10 times the rated current. It is ideal for circuits with moderate inrush currents, such as those powering motors, HVAC systems, fluorescent lighting, and general-purpose three-phase loads. The C curve strikes a balance between sensitivity and selectivity, avoiding nuisance tripping while still reacting quickly to faults.
The NCN320A offers dual breaking capacity ratings:
-
10kA according to IEC/EN 60898
-
15kA according to IEC/EN 60947-2
These ratings ensure it can handle higher fault currents in demanding environments, providing added resilience in industrial applications.
With a 3-module width, the MCB fits easily into standard DIN rail-mounted enclosures and distribution boards. It is designed with secure terminals and clear labelling to support fast, error-free installation.
