What it is and what the ratings mean for fit
The Siemens 3VA1110-5MH36-0DA0 is a 3-pole IEC frame 160 MCCB rated 100 A continuous, with a TM120M trip unit for starter protection. The magnetic short-circuit pickup Ii is adjustable 5...15 x In. The 55 kA interrupting capacity at 415 V (class M) is the figure a panel designer needs for SCCR compliance. The built-in undervoltage release (UVR) operates on 208-230 V AC 50/60 Hz, so if the control voltage drops, the breaker trips — standard for safety circuits that need automatic disconnect on power loss. Clamp terminals accept copper conductors up to the frame's rating; no lug kit needed for most panel builds.
Panel integration notes
Mounts on a standard DIN rail or can be screw-mounted to a backplate — the IEC frame 160 footprint fits common panel layouts. The clamp terminals accept solid or stranded copper; torque to the value marked on the terminal label. The UVR coil draws a small continuous current when energized; verify the control transformer VA budget if sharing with other loads.
