At 55 °C it's still 155.6 A, and at 70 °C it's 142.4 A. The TM240 thermal-magnetic release handles the overload and short-circuit curve, so you set the thermal pickup to match your feeder or load. Breaking capacity is what decides whether this breaker holds on a fault or vents. At 240 V it clears 121 kA; at 415 V it's 75.6 kA; at 440 V it's 25 kA; at 690 V it's 11.9 kA. That's a high-interrupting rating for a 160 A frame — it gives you selectivity headroom upstream of a transformer or a large motor branch without stepping up to a bigger breaker.
Built-in auxiliaries and trip options
The shunt trip order code is 3VA9688-0BL33; if you're ordering spares or a replacement coil, that's the number to match. The trip indicator is not fitted on this unit — if you need a visual flag that the breaker has tripped remotely, you'd spec a different version or add an external indication. Phase failure detection is also absent, so this is a straight line-protection breaker, not a motor-protection device with phase-loss sensing.
Environmental and compliance range
The storage max is the handling limit — don't leave it in a hot warehouse truck in summer, but it'll survive.
