SENTRON 3VA1010-4ED32-0DC0 — 100 A MCCB with Undervoltage Release
The Siemens 3VA1010-4ED32-0DC0 is a SENTRON molded case circuit breaker (MCCB) rated for 100 A continuous at 40 °C, with a 3-pole configuration and an integrated undervoltage release (UVR). It is designed for line protection in distribution panels and switchboards, carrying a 121 kA interrupting rating at 240 V AC and 75.6 kA at 415 V AC.
Breaking Capacity and Selectivity Planning
This MCCB delivers 121 kA at 240 V, 75.6 kA at 415 V, 52.5 kA at 440 V, and 11.9 kA at both 500 V and 690 V. The high 121 kA figure at 240 V gives headroom for fault-current coordination downstream — useful when the upstream transformer or service entrance can deliver that level of prospective short-circuit current. At 690 V the 11.9 kA rating still covers most motor-circuit fault levels in industrial 690 V networks.
Thermal Derating and Continuous Current
Rated 100 A from 40 °C through 50 °C ambient. At 55 °C it derates to 98 A, at 60 °C to 96 A, at 65 °C to 94 A, and at 70 °C to 91 A. The 800 V rated insulation voltage (Ui) supports use in 480 V and 600 V class panels with margin. Maximum power loss is 27.5 W — factor that into enclosure thermal calculations when grouping multiple breakers.
Physical Fit and Panel Integration
Dimensions: 130 mm height, 76.2 mm width, 70 mm depth. The 3-pole width (76.2 mm) is standard for a 100 A frame MCCB — it occupies three 25.4 mm pole spaces on a DIN rail or panel-mount footprint. The depth of 70 mm leaves clearance for rear-connected busbars or cable lugs in a typical distribution cabinet.
