Overcurrent circuit breaker Icu=50kA 2P C 16A HMX216

Operates in industrial and commercial installations where high breaking capacity is required

The circuit breaker is rated to withstand short‑circuit currents up to 50 kA at 230 V and 400 V — meaning it can safely interrupt even extremely high fault currents that may occur in modern high‑source‑power circuits. No need to worry about its performance in locations where the installation is close to a transformer or in motor circuits.

Characteristic C enables stable starting of motor‑driven equipment

It does not trip unintentionally on short current spikes — ideal for protecting pumps, fans, compressors or other equipment with asynchronous motors. During start‑up of such equipment there are no false trips, because the trip unit reacts only after a prolonged overload.

DIN‑rail mounting and compatibility with other modules

It has a width of 3 modules and is designed for surface‑mount installation on a DIN rail. Upper and lower terminals are aligned — facilitating connection with other circuit breakers or residual‑current devices without the need for additional adapters. All terminals are screw‑type, and the tightening torque of 3.6 Nm is clearly specified — no guessing how much force is required.

Terminals for various conductor types

Both solid (rigid) single‑core and stranded (flexible) multi‑core conductors can be connected. Rigid conductors up to 70 mm², flexible up to 50 mm² — so a separate breaker for larger conductors is not necessary. One model covers many applications.

Operates in extreme climatic conditions

Temperature range from –25 °C to +70 °C means it can be installed even in unheated rooms, outdoors in distribution cabinets, or in locations with large temperature swings. Protection class IP20 guards against finger contact and small objects — sufficient for indoor use.

Energy‑limiting class 3 — faster arc extinguishing

In the event of a fault, the energy released by the breaker is limited to class 3 — resulting in reduced contact damage and lower risk of damage to downstream equipment. This not only enhances installation safety but also extends the breaker’s service life.

Compliant with IEC 60947-2 and IEC 60898-1 standards

This is not a “general‑purpose” breaker — it meets IEC requirements for industrial equipment (IEC 60947-2) as well as domestic applications (IEC 60898-1), making it universal for both building installers and production‑line specialists. Insulation voltage 500 V and impulse voltage 6 kV provide an additional safety margin.
