The TM210 trip unit gives you thermal-magnetic protection: the thermal element (Ir) is permanently set at 45 A for overloads, and the magnetic instantaneous pickup (Ii) is fixed at 10x In (450 A) for short circuits. No field adjustment on the trip settings — what you order is what protects the feeder. RoHS compliant since May 2019. The 3-pole format occupies three module widths (about 54 mm). With the TM210 fixed-trip thermal-magnetic unit, there's no adjustment knob to reach — good for sealed panels where you don't want settings changed in the field. The load-side terminals accept copper or aluminum conductors up to the frame rating; torque per the nameplate values.","metaTitle":"Siemens 3VA4145-4ED34-3AA0 Circuit Breaker, 45 A, 25 kA @ 48","metaDescription":"Siemens 3VA4145-4ED34-3AA0 circuit breaker, 3-pole, 45 A, 25 kA @ 480 V, UL Frame 125, active production.
