The interrupting ratings are the headline: 187 kA at 240 V, 121 kA at 415 V, 75.6 kA at 440 V, and 17 kA at 690 V. That 187 kA figure at 240 V is high enough for most secondary-side fault duty; the 17 kA at 690 V tells you it's still usable on 690 V systems where SCCR is modest. ## Thermal-magnetic release and auxiliary fit The overcurrent release is a TM220 — thermal-magnetic, fixed-trip, the standard workhorse for line protection. The auxiliary contact version is 2 auxiliary switches HQ (high-qualified), and the integrated auxiliary trip is a shunt trip (STL) with order code 3VA9688-0BL33. If you need undervoltage release, this unit doesn't carry one; that's a separate variant. Front protection is IP40 — fine for a dry panel, not for washdown. The 70 mm depth is standard for this frame size; it fits the usual DIN-rail or screw-mount footprint without surprises.","metaTitle":"Siemens 3VA1110-5EE32-0KC0 SENTRON MCCB, 100 A, 187 kA at 24","metaDescription":"Siemens SENTRON 3VA1110-5EE32-0KC0 molded case circuit breaker, 100 A rated, 187 kA at 240 V. 3-pole, TM220 release, shunt trip.

The difference is in the auxiliary contact configuration and possibly the shunt trip variant.
