The TM210 thermal-magnetic release provides fixed LI protection — the instantaneous trip (Ii) is fixed at 1250 A, ten times the continuous rating, which gives good inrush headroom for motor or transformer branch circuits without nuisance tripping on startup. Interrupting capacity is 75.6 kA at 240 V AC and 9 kA at 415 V AC — the 240 V figure covers most North American panelboard applications, while the 415 V rating suits IEC distribution where fault currents are lower. The 1-pole format fits standard 25.4 mm (1 in) per-pole width on DIN rail, matching the SENTRON 3VA family footprint for easy retrofit or new build. ## Integration and deployment The 70 mm depth (2.76 in) leaves clearance behind the door for wiring and auxiliary accessories.","metaTitle":"Siemens 3VA1112-4ED12-0AA0 SENTRON MCCB, 125 A, 1-Pole, TM21","metaDescription":"Siemens 3VA1112-4ED12-0AA0 SENTRON molded case circuit breaker, 125 A rated, 1-pole, TM210 release, 75.6 kA at 240 V.
