It carries a TM240 thermal-magnetic release, meaning the thermal element is fixed at 160 A and the magnetic trip is adjustable up to 240 A — the setting that governs short-circuit protection for the downstream load. The breaker is designated for line protection, so it's the primary overcurrent device feeding a distribution bus or a large motor control center, not a branch-circuit-only device. At 240 V it interrupts 187 kA; at 415 V that drops to 121 kA; at 440 V it's 36 kA; at 690 V it's 17 kA.
Dimensions are 105 mm wide, 158 mm high, 70 mm deep. That gives you two form-C contacts for status feedback (open/closed) and a separate alarm contact that changes state only when the breaker trips on fault — useful for remote annunciation without wiring through the main contacts. No undervoltage release or shunt trip is fitted; those would need to be added as field-installable accessories if required.
Thermal derating and environment
Above that it derates: 155.6 A at 55 °C, 151.2 A at 60 °C, 146.8 A at 65 °C, and 142.4 A at 70 °C.
