The SENTRON 3VM1110-3EE36-0AA2 is a 3-pole molded case circuit breaker (MCCB) from the 3VM1 frame, rated for 100 A continuous current at 40 °C and carrying a class N breaking capacity of 76 kA at 240 V AC. It's a line-protection device with a TM220 thermal-magnetic release — the thermal element adjustable from 70 A to 100 A, the magnetic fixed at 10× In. That means for a 100 A feeder, the instantaneous trip sits at 1000 A, which keeps it selective downstream of most 160 A–250 A upstream breakers in a typical 480 V distribution panel.
Breaking capacity across voltages — what it means for your panel
This MCCB's interrupting rating drops as voltage rises: 76 kA at 240 V, 53 kA at 415 V, 32 kA at 440 V, and 11.9 kA at 500 V. The class N designation tells you it's the economy tier in the 3VM1 family — fine for most commercial and light industrial panels where the available fault current stays under 25 kA at 415 V, but not for high-fault substations. If your SCCR study shows fault current above 53 kA at 415 V, you need the class S or H version. The 690 V rated insulation voltage (Ui) means the internal clearances and creepage are sized for 690 V systems, so it's safe on 480 V or 600 V delta services.
Thermal derating and ambient temperature
The breaker holds full 100 A from 40 °C up to 50 °C without derating. Above that, it steps down: 98 A at 55 °C, 96 A at 60 °C, 94 A at 65 °C, and 91 A at 70 °C. If your panel runs hot — say a non-ventilated enclosure near a furnace line — you'll need to account for that 9 % loss at the top end. The operating range is -25 °C to 70 °C, storage from -40 °C to 80 °C. Power loss is 25 W max at rated current, so factor that into your enclosure thermal budget.
What's in the box — connections and accessories
The main circuit connects via box terminals on the front — standard for panel wiring with ring lugs or fork terminals. No auxiliary contacts come built in (0 CO contacts), and there's no provision for a motor drive or neutral conductor upgrade. Communication function is absent, so no Modbus or PROFIBUS integration here — it's a straight electromechanical breaker. IP40 on the front means it's protected against tools and wires >1 mm, but not against dust ingress; mount it inside a closed panel.
