Breaking capacity is the headline: 187 kA at 240 V, 121 kA at 415 V, 75.6 kA at 440 V, and still 17 kA at 500 V and 690 V. Dimensions are 130 mm high, 76.2 mm wide, 70 mm deep — a standard 3-pole MCCB footprint that drops into most Siemens 3VA panelboards and distribution blocks without adapter plates. The 70 mm depth means it clears shallow backpan enclosures where deeper breakers would force a gutter extension. Maximum power loss at rated load is 27.5 W — factor that into your enclosure thermal calculation if you're packing multiple breakers in a sealed box. The undervoltage release is factory-integrated, so you don't lose a pole position for an add-on accessory. The base switch assembly part number is 3VA11105EF360AA0 — that's the naked mechanism without the UVR. If you ever need to replace just the switch body and reuse the undervoltage release, that's the reference to give your Siemens rep.","metaTitle":"Siemens 3VA1110-5EF36-0CA0 SENTRON MCCB, 100A, 3-Pole, 187kA","metaDescription":"Siemens SENTRON 3VA1110-5EF36-0CA0 molded case circuit breaker, 100A rated at 40°C, 3-pole, 187kA breaking at 240V.
