What this breaker does on a motor circuit
The C25V32M220 is a ComPacT NSX moulded-case circuit breaker with a MicroLogic 2.2 M electronic trip unit, rated 220 A at 65 °C and built for motor protection.
Mounts on a backplate in either horizontal or vertical orientation. Front connections top and bottom, 35 mm pitch between poles. IP40 enclosure protection, IK07 impact resistance. Overvoltage category III, so it handles fixed-installation transients.
Rated for 20,000 mechanical cycles. Electrical endurance: 20,000 cycles at 440 V at half rated current, 10,000 cycles at full rated current, and 5,000 cycles at 690 V full current. Motor tripping class options 10, 5, or 20 — the 20-minute thermal memory matches Class 20 starts well. Utilisation category A (non-delayed short-circuit).
