What the interrupting ratings mean for your panel
The Siemens SENTRON 3VA1110-5EF36-0AD0 is a 3-pole molded case circuit breaker rated for line protection, carrying 100 A continuously up to 50 °C without derating. At 55 °C it holds 98 A, at 60 °C it holds 96 A, and at 70 °C it holds 91 A — so in a warm enclosure you lose about 9 % of capacity at the top end. 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 both 500 V and 690 V. That 187 kA at 240 V means this breaker can safely clear a fault up to that level without rupturing — critical for high-fault panels near large transformers or utility feeds. The TM240 thermal-magnetic release gives fixed thermal and magnetic trip settings; no voltage trigger or undervoltage release is fitted. Three HQ auxiliary switches are built in for status feedback to a PLC or alarm panel.
DIN-rail footprint and panel fit
At 70 mm deep, 76.2 mm wide, and 130 mm tall, this MCCB fits a standard 3-pole breaker slot in a SENTRON distribution panel or on a DIN rail. The IP40 front rating means it's protected against tools and wires >1 mm but not against water — keep it inside a closed enclosure. The 25 W maximum power loss matters for thermal budgeting in a sealed cabinet; if you're packing multiple breakers side by side, account for that heat.
How it compares to the 3VA1110-5ED36-0AC0
The closest sibling is the 3VA1110-5ED36-0AC0. Both are 3-pole, 100 A SENTRON MCCBs with the same physical footprint. The difference is the release: this 5EF36 carries the TM240 thermal-magnetic release, while the 5ED36 uses a different release variant. If your panel was specced around the 5ED36, this 5EF36 will drop into the same mounting and busbar pattern — no rewiring needed — but verify the trip curve matches your coordination study. The interrupting ratings and aux switch count are identical.
