Line protection breaker — 160 A, 4-pole, TM210 release
It's designed for line protection duty — meaning it sits upstream protecting feeders and distribution, not a specific motor or load group. Breaking capacity runs 121 kA at 240 V AC, 76 kA at 415 V, and 53 kA at 440 V — numbers that put it in the high-interrupting range for a 160 A frame.
Above that it derates gradually — 158 A at 55 °C, 155 A at 60 °C, 153 A at 65 °C, and 150 A at 70 °C. Dimensions are 70 mm deep, 101.6 mm wide, and 130 mm tall — a compact footprint for a 160 A 4-pole MCCB.
