It is designed for residential and infrastructure branch-circuit protection where the B-curve's instantaneous trip threshold (3 to 5 times In) suits resistive and light inductive loads such as lighting, socket outlets, and small appliances.
Breaking capacity and voltage range
The MCB accepts a single-phase supply up to 253 V AC and multi-phase (line-to-line) up to 440 V AC, covering standard 230/400 V networks at 50/60 Hz. DC-rated maximum is 72 V, so it can also switch a 48 V DC control circuit in a pinch, though the DC breaking capacity is not separately stated.
DIN-rail footprint and installation
Width is 36 mm (2 modular units), depth 76 mm, height 90 mm — it occupies two standard 18 mm DIN-rail slots. Sealable terminals allow the installer to lock the cover after commissioning, preventing tamper.
