SENTRON 3VA2110-7MN36-0DC0 — 100 A MCCB with ETU350M, 330 kA at 240 V
The Siemens 3VA2110-7MN36-0DC0 is a 3-pole SENTRON molded case circuit breaker (MCCB) rated for motor protection. Its ETU350M electronic trip unit with phase failure detection and undervoltage release (UVR) makes it a fit for motor branch circuits where you need adjustable protection and remote drop-out capability. Rated continuous current Iu is 100 A, and it holds that rating from 40 °C up to 50 °C without derating. At 70 °C ambient it still carries 90 A — useful for a crowded panel where the internal temperature runs high. Interrupting capacity is 330 kA at 240 V, 242 kA at 415 V and 440 V, 187 kA at 500 V, and 52.5 kA at 690 V. That 330 kA figure at 240 V covers high-fault locations like a transformer secondary or a large UPS bypass; the 52.5 kA at 690 V is still substantial for most industrial 690 V distribution. Dimensions are 105 mm wide, 181 mm high, 86 mm deep — a standard SENTRON 3VA2 footprint that fits the same DIN-rail or screw-mount pattern as the rest of the 3VA2 family. The 86 mm depth leaves room for rear-connected busbars in a typical distribution panel.
Sourcing and lifecycle
Maximum power loss is 75 W — factor that into the panel thermal budget if you are grouping several breakers in a sealed enclosure.
Integration and compliance
The 3VA2110-7MN36-0DC0 ships with 2 auxiliary switches (HQ type) pre-installed — order code 3VA9608-0BB25 for the auxiliary trip block. The undervoltage release (UVR) is integrated, so no separate coil wiring is needed for remote shunt-trip capability. Operating temperature range is -25 °C to 70 °C; storage range is -40 °C to 80 °C. The 800 V rated insulation voltage (Ui) covers 480 V and 600 V class systems with margin. Compliance documentation (RoHS, REACH, UL, IEC) is standard for the SENTRON series and accompanies the shipment. The part carries a CE marking for the European market.
