The C160H32EFM is a 3-pole fixed-mount ComPacT NS new generation MCCB rated 1600 A at 50 °C, carrying a MicroLogic 2.0 E electronic trip unit with L (long-time overload) and I (instantaneous short-circuit) protection curves. The 74 W power loss at rated current matters for enclosure thermal budgeting; plan ventilation accordingly. The 1600 A frame covers main incoming feeders or large bus risers in industrial and commercial switchboards. Fixed mounting on a backplate with front connections top and bottom keeps the wiring pattern predictable for panel builders.
The 85 kA Icu at 240 V and 70 kA at 415 V give the C160H32EFM headroom for high-available-fault installations. The 65 kA at 440 V and 50 kA at 500/525 V still cover most industrial service entrances. At 660/690 V it holds 42 kA — useful for 600 V class systems. These ratings conform to IEC 60947-2 Category B, meaning the breaker is fully selective with downstream devices under short-circuit conditions. The MicroLogic 2.0 E trip unit provides LSI protection via electronic sensing. Thermal memory holds for 20 minutes after a trip, preventing immediate reclose on a still-hot conductor. The LCD display shows measured values and fault type, and the four red LEDs indicate the fault cause — overload, short-circuit, or ground fault (though this unit ships without earth-leakage protection).
Fixed mounting on a backplate with 70 mm connection pitch. Front connections both top and bottom. Dimensions: 327 mm high, 210 mm wide, 147 mm deep. IK07 impact resistance handles incidental contact in a panel. Manually operated with an LCD display for local metering and energy measurement. The electronic trip unit draws power from the line side — no auxiliary supply needed for basic protection.
