The interrupting capacity is the headline number here: 187 kA at 240 V, 121 kA at 415 V, 75.6 kA at 440 V, and 17 kA at 690 V. At 415 V, the 121 kA rating still puts it in the top tier for industrial MCCBs; most standard panels won't see that level, so you've got headroom for selectivity coordination downstream. ## TM240 release and trip characteristics The overcurrent release is a TM240 thermal-magnetic type — fixed thermal pickup, magnetic trip adjustable. The thermal element tracks the 100 A frame rating; the magnetic short-circuit pickup is set at the factory per the TM240 curve. No undervoltage release, no shunt trip, no ground-fault module on this variant — it's a straight line-protection breaker with a 1 NO + 1 NC auxiliary switch and a separate trip-alarm switch (HQ configuration). The 3VA1110 frame measures 130 mm high, 76.2 mm wide, and 70 mm deep. That 76.2 mm width is a standard 3-pole MCCB footprint — three 25.4 mm pole centers — so it drops into existing SENTRON or 3VA panelboards without re-drilling. Front IP40 protection handles typical indoor panel environments; no washdown rating, so keep it inside the enclosure. The trip indicator on the front gives a visual flag for a tripped state without needing to open the door.","metaTitle":"Siemens 3VA1110-5EF36-0AF0 SENTRON MCCB, 100 A, 3-Pole, 187","metaDescription":"Siemens 3VA1110-5EF36-0AF0 SENTRON molded case circuit breaker, 100 A rated, 3-pole, TM240 release, 187 kA at 240 V.

The difference is the auxiliary contact configuration: this -0AF0 carries 1 auxiliary switch + 1 trip alarm switch (HQ), while the -0AD0 has a different auxiliary contact arrangement.
