Interrupting capacity hits 187 kA at 240 VAC, 121 kA at 415 V, 75.6 kA at 440 V, and still 17 kA at 500 V and 690 V — that's a high-fault-rated breaker for distribution boards where upstream transformer capacity is substantial. Footprint is 76.2 mm wide by 130 mm tall by 70 mm deep — three standard 25 mm module widths on a DIN rail, which means it drops into a 3-module slot in most SENTRON panelboards without adapters. ## Thermal-magnetic release and line protection duty That keeps the part simple and repeatable for BOM-locked line protection where you want the same trip characteristic every time.","metaTitle":"Siemens 3VA1120-5ED36-0AA0 SENTRON MCCB, 3-pole, 20 A, TM210","metaDescription":"Siemens 3VA1120-5ED36-0AA0 SENTRON molded case circuit breaker, 3-pole, 20 A rated, TM210 thermal-magnetic release, 187 kA interrupting capacity at 240 VAC.
