The C160N360FM is a Schneider Electric ComPacT NS new generation 3-pole circuit breaker rated 1600 A at 50 °C with a MicroLogic 6.0 electronic trip unit providing LSI protection (long-time, short-time, instantaneous). Its 85 kA Icu at 240 V AC and 50 kA Icu at 415 V AC per IEC 60947-2 mean it can safely interrupt fault currents up to those levels without upstream damage — critical for main or feeder breakers in distribution panels where high available fault current is expected. The breaker is manually operated, fixed-mounted to a backplate, and sized at 210 mm wide × 327 mm high × 147 mm deep — a footprint that fits standard switchboard compartments. Power losses are 74 W at rated current — a figure to budget for in enclosure thermal calculations, especially when multiple breakers are ganged. The IP40 front face and IK07 impact resistance suit indoor distribution boards; pollution degree 3 per IEC 60947 means it tolerates conductive pollution in industrial environments.
Protection & Selectivity
The MicroLogic 6.0 trip unit covers overload (L), short-time short-circuit (S), and instantaneous (I) protection. The electronic design allows adjustable pickup and time-delay settings on the L and S curves, enabling selective coordination with downstream breakers — a key requirement for service continuity in a distribution hierarchy. Thermal memory of 20 minutes prevents nuisance tripping on reclose after a mild overload.
Mechanical & Electrical Endurance
Mechanical durability is 10,000 cycles; electrical durability varies with load: 1,000 cycles at 690 V In, 2,000 cycles at 690 V In/2, 2,000 cycles at 440 V In, and 5,000 cycles at 440 V In/2. These figures guide maintenance scheduling for high-cycling applications like motor control centers or capacitor bank switching.
Environmental & Mounting
Operating altitude is 0 to 2000 m without derating, 2000 m to 5000 m with derating. Relative humidity range 0 to 95 %. Connection pitch is 70 mm between phase centers — standard for this frame size and compatible with common busbar systems.
