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. RoHS compliant since 13 May 2019.","metaTitle":"3VA4140-5ED34-3AA0 Siemens 3VA4 Circuit Breaker, 40 A, 35 kA","metaDescription":"Siemens 3VA4140-5ED34-3AA0 circuit breaker, 40 A, 35 kA @ 480 V, 3-pole, TM210 thermal-magnetic trip.
