It is rated 40 A continuous with a thermal-magnetic TM210 trip unit — overload protection fixed at Ir=40 A, short-circuit pickup at Ii=10 x In (400 A). The TM210 trip is a fixed thermal-magnetic design: the thermal element tracks RMS heating for overloads, the magnetic element responds instantaneously to short-circuit currents. No adjustable dials on the trip unit — Ir and Ii are factory-set. This simplifies specification for a fixed-load panel but means the breaker is not field-adjustable for changing loads.
At 472 x 396 x 213 mm packaged, the breaker itself fits a standard MCCB footprint for panel layouts. Spring-cage or box lug terminals accept copper or aluminum conductors — verify lug torque values per the terminal marking during panel build.
