The C160N45EFM is a 4-pole ComPacT NS new generation molded case circuit breaker rated 1600 A at 50 °C, with a MicroLogic 5.0 E electronic trip unit that provides L (long-time overload), S (short-time short-circuit), and I (instantaneous short-circuit) protection. The IEC 60947-2 Category B utilization confirms it is designed for selectivity in distribution, not just cable protection. At 147 mm deep, 280 mm wide, and 327 mm tall, this fixed-mount breaker bolts to a backplate with a 70 mm connection pitch. The front-facing connections (upside and downside) simplify busbar or cable routing in a switchboard — no rear-access required. IP40 front face and IK07 impact rating handle the usual panel environment; pollution degree 3 means it tolerates conductive dust in industrial enclosures.
Deployment context
This breaker is sized for main or feeder protection in a 1600 A distribution switchboard — think a factory main incoming, a large motor control center, or a data-center PDU. The MicroLogic 5.0 E trip unit includes an energy meter (type of measurement: energy meter), so it doubles as a revenue-grade metering point without an extra CT cabinet. The LCD display shows real-time current, energy, and trip data locally. Mechanical durability is 10,000 cycles; electrical durability ranges from 1,000 cycles at 690 V In up to 5,000 cycles at 440 V In/2. That is typical for a distribution breaker — not rated for frequent switching like a contactor, but fine for infrequent disconnect duty. The 20-minute thermal memory means the trip unit remembers prior heating, so a reclose after a near-trip event is safer.
