The TM210 trip unit gives you fixed thermal-magnetic protection: Ir is permanently set at 20 A for overloads, and the magnetic short-circuit pickup (Ii) is locked at 15× In, or 300 A. No field-adjustable dials on this one — what you order is what protects your circuit. The 2-pole footprint takes up one module width per pole, so plan for two 18 mm slots. Line and load lugs accept copper or aluminum conductors — torque per the label on the front. Because it's a fixed-trip TM210, there's no rotary dial to accidentally bump during commissioning; what's set at the factory stays set.","metaTitle":"Siemens 3VA4120-4ED24-3AA0 Circuit Breaker, 20A, 25kA @ 480V","metaDescription":"Siemens 3VA4120-4ED24-3AA0 circuit breaker, UL Frame 125, 2-pole, 20A, 25kA @ 480V.
