Its interrupting capacity reaches 220 kA at 240 V AC, dropping to 154 kA at 415 V and 75.6 kA at 440 V — figures that govern selectivity and SCCR coordination downstream. At 690 V it still clears 17 kA, so this frame handles industrial supply voltages without cascading upstream breakers.
Full 160 A rating holds through 50 °C ambient; at 55 °C it derates to 158 A, at 60 °C to 155 A, and at 70 °C to 150 A. That means in a sealed enclosure with no forced cooling you still get 150 A of continuous capacity. The 70 mm depth and 101.6 mm width fit standard MCCB mounting footprints — check gland-plate clearance for the 4-pole lug arrangement. Maximum power loss is 38 W, which matters for thermal rise in a multi-breaker lineup.
Compliance and approvals context
Rated insulation voltage 800 V, IP40 on the front face. The TM210 overcurrent release provides thermal-magnetic protection for line distribution. Standard compliance documentation (CE, UL, IEC 60947-2) applies per the SENTRON series; verify specific certification marks for your jurisdiction at quote time.
