The Siemens SENTRON 3VA1110-3EF36-0JH0 is a 3-pole molded case circuit breaker (MCCB) rated for line protection, with a continuous current of 100 A at 40 °C and a breaking capacity of 75.6 kA at 240 V. That 75.6 kA interrupting rating at 240 V means it can safely clear a fault up to that level without upstream devices needing to trip — critical for high-fault panels near transformers or large motor banks. At 415 V the breaking capacity is 52.5 kA, and at 690 V it holds at 11.9 kA, so the SCCR you coordinate depends on the system voltage.
Ratings and what they mean for fit
The 100 A rating holds flat from 40 °C to 50 °C — no derating needed in a typical 40 °C panel. Above that, it drops to 98 A at 55 °C, 96 A at 60 °C, 94 A at 65 °C, and 91 A at 70 °C. If your enclosure runs hot (say, a packed panel near a furnace), size the load at 91 A continuous to stay within the 70 °C limit. The insulation voltage is rated 800 V, so the breaker is suitable for 690 V systems with margin. Dimensions are 130 mm high, 76.2 mm wide, 70 mm deep. That 70 mm depth is shallow enough to fit in most standard distribution panels without interfering with the gland plate or rear busbars. The 76.2 mm width (3 inches) is the standard 3-pole MCCB footprint — it will drop into a panel designed for a 3VA1010-2ED32-0JA0 or similar SENTRON frame without rewiring, as long as the busbar and lug positions match. Power loss is 25 W maximum at rated load. For a panel with multiple breakers, that heat adds up — factor it into your thermal budget if you're packing more than a few units in a sealed enclosure.
Auxiliary and trip options
The breaker ships with a shunt trip (STL) auxiliary release and a configuration of 2 auxiliary switches plus 1 trip alarm switch (HQ). The trip indicator and voltage trigger are present; undervoltage release is not fitted. No ground-fault monitoring version, no communication function — this is a pure line-protection device, not a power-monitoring breaker.
