The Siemens 3VA1110-6MH36-0DA0 is a 3-pole IEC frame 160 molded case circuit breaker (MCCB) from the 3VA1 series, rated at 100 A with a breaking capacity class H — Icu of 70 kA at 415 V AC. That 70 kA interrupting rating means it can safely clear a bolted fault up to that level without rupturing or cascading upstream, which is the figure that governs panel SCCR compliance in IEC 61439 switchgear assemblies. The unit carries a TM120M thermal-magnetic trip for starter protection (motor branch-circuit protection per IEC 60947-4-1) with adjustable short-circuit pickup Ii = 5...15 x In, and includes an undervoltage release (UVR) coil rated 208-230 V AC 50/60 Hz. Connection is via clamp terminals.
Integration Notes
Mounts on a DIN rail or panel-mount via the 3VA1 base adapters. The clamp terminals accept copper or aluminum conductors up to the frame's rated cross-section; torque values per the mounting instructions on the nameplate. The UVR coil draws its control voltage from a separate 208-230 V AC supply — not from the breaker's load side — so verify the control transformer tap before energizing. The TM120M trip provides motor overload protection; the adjustable short-circuit pickup (Ii) lets you coordinate with downstream contactors and starters.
