Part identity and key ratings
It carries a continuous current rating of 160 A across the 40 °C to 50 °C ambient band, derating to 150 A at 70 °C. The interrupting capacity is 187 kA at 240 V AC, 121 kA at 415 V AC, 75.6 kA at 440 V AC, and 17 kA at both 500 V and 690 V AC.
The TM210 release means the thermal element handles overloads and the magnetic element handles short circuits — no electronic trip unit adjustments, so it's a fixed-characteristic breaker for straightforward line protection. The 4-pole configuration covers three-phase plus neutral, or can be used as a four-wire disconnect.
The 101.6 mm (4-inch) width is standard for a 4-pole MCCB in this frame size — check your enclosure's back-panel or DIN-rail layout for that footprint. Front IP40 protection means it's splash-proof from the front but not sealed against dust ingress around the sides or rear; mount it inside a panel with a door, not in an open washdown zone.
