What this MCCB delivers in the panel
The Siemens SENTRON 3VA2110-5HL36-0AG0 is a 3-pole molded case circuit breaker (MCCB) rated for 100 A continuous current at 40 °C, carrying the same 100 A rating through 50 °C before the thermal derating curve begins — at 55 °C it's 96.25 A, at 60 °C it's 92.5 A, and at 70 °C it's 85 A. That means for a panel sitting at 50 °C ambient (common in a crowded enclosure), you still get full 100 A without oversizing the frame. The interrupting ratings climb to 187 kA at 240 V and 121 kA at 415 V, so this breaker handles high-fault utility feeds and transformer secondaries without cascading upstream. The ETU320 electronic trip unit gives you adjustable long-time, short-time, and instantaneous protection — no thermal bimetal drift to account for on a warm day.
Sizing and integration into a DIN-rail enclosure
At 105 mm wide, 181 mm tall, and 86 mm deep, this 3VA frame fits standard Siemens panel cutouts and busbar risers. The IP40 front protection means it's fine for a clean indoor panel; it's not rated for washdown zones. The auxiliary contact configuration ships as 1 auxiliary switch plus 1 trip alarm switch (HP type) — that gives you one NO/NC for status feedback to the PLC and one dedicated alarm contact for the trip event, so you don't have to share or add a separate alarm module. Maximum power loss is 10 W, which is modest for a 100 A frame — keep that in mind for thermal calculations in a sealed enclosure.
Sourcing this for a BOM line
The 3VA2110-5HL36-0AG0 is specified into the BOM as a line-protection MCCB with the ETU320 release. It is sourced and quoted to order against an RFQ through independent distribution — availability and current pricing are confirmed at quote time. For a panel originally built around the 3VA1010-2ED36-0AC0, this 3VA2110 frame is a different physical size and trip unit generation; it will not drop into the same cutout without panel modification. The 3VA2110 is the larger frame for higher interrupting capacity and the electronic trip option.
