MCCB for line protection — 160 A, high interrupting capacity
This MCCB is designed for main feeder or large branch protection in distribution panels where fault current levels are high. Interrupting capacity is the headline spec here: 187 kA at 240 V, 121 kA at 415 V, 75.6 kA at 440 V, and 17 kA at 690 V. That puts it in the high-fault-current tier — suitable for service-entrance or transformer-fed switchboards where downstream breakers need a high SCCR upstream to coordinate. Thermal derating is published across the full operating range: full 160 A up to 50 °C, then steps down to 153.6 A at 55 °C, 150.4 A at 60 °C, 147.2 A at 65 °C, and 144 A at 70 °C.
Integration — panel fit and wiring
No auxiliary contacts or ground-fault module are included; those are add-on options if needed. The breaker is rated for 15,000 mechanical latching endurance cycles — typical for a fixed-mounted MCCB in a distribution panel that sees infrequent switching. No communication function, no phase-failure detection, and no voltage trigger are built in; this is a straightforward thermal-magnetic protective device.
