Above that, the TM210 bimetal element responds to the higher internal temperature, so the load must be trimmed accordingly. This MCCB's breaking capacity varies significantly with system voltage. At 240 VAC it interrupts 121 kA — sufficient for high-fault locations near a large transformer. At 415 VAC the rating is 75.6 kA, at 440 VAC it is 52.5 kA, and at 500 VAC and 690 VAC it holds at 11.9 kA. For DC applications, the manufacturer directs users to the 3VA device manual for switching power values.","metaTitle":"Siemens 3VA1150-4ED46-0AA0 SENTRON MCCB, 50A, 4-Pole, 121kA","metaDescription":"Siemens 3VA1150-4ED46-0AA0 SENTRON molded case circuit breaker, 50A, 4-pole, TM210 release, 121 kA at 240 VAC.
