It's rated 40 A continuous with a breaking capacity of 35 kA at 277 V — class M, meaning it handles moderate fault currents typical of North American commercial and light industrial panelboards. The TM210 line protection trip unit provides fixed overload protection at Ir = 40 A and a short-circuit pickup set at Ii = 10 × In (400 A). 35 kA interrupting rating at 277 V, class M. Fixed Ir=40 A — no field adjustment.","metaTitle":"Siemens 3VA4140-5ED14-3AA0 Circuit Breaker, 40 A, 35 kA @ 27","metaDescription":"Siemens 3VA4140-5ED14-3AA0 circuit breaker, 1-pole, 40 A, 35 kA @ 277 V, UL Frame 125, line protection TM210.
