What this MCCB is and what it does
The Siemens 3VA1110-5ED36-0AC0 is a SENTRON molded case circuit breaker (MCCB) rated for 100 A continuous at 40 °C, with a 3-pole configuration and a TM210 thermal-magnetic overcurrent release. Its interrupting capacity hits 187 kA at 240 V AC, dropping to 121 kA at 415 V and 75.6 kA at 440 V — numbers that tell you it's built for high-fault industrial distribution, not light commercial service. The TM210 release means the thermal element is fixed at 100 A and the magnetic pickup is adjustable (typically 5–10x In), so you set the short-circuit trip threshold to coordinate with downstream feeders.
What the ratings mean for your panel
At 100 A continuous, this MCCB carries a full 3-phase load without derating up to 50 °C; above that it drops to 98 A at 55 °C and 91 A at 70 °C. The 800 V rated insulation voltage (Ui) means it's safe for 480 V and 600 V class systems with margin. Power loss is 25 W max — negligible for panel thermal budgeting but worth noting if you're packing breakers tight in a sealed enclosure. Dimensions are 70 mm deep, 76.2 mm wide, 130 mm tall — a standard SENTRON 3VA footprint that fits the existing mounting base and busbar system.
Auxiliary switching and release options
The breaker ships with 2 auxiliary switches (HQ design) for status feedback to a PLC or annunciator panel. No undervoltage release, no shunt trip, no ground-fault monitoring on this variant — if you need those, you're looking at a different suffix in the 3VA family. The basic switch assembly is order code 3VA11105ED360AA0, which is the internal mechanism; you're buying the complete breaker here.
