What this breaker delivers
The Siemens 3VA2110-6HL36-0DH0 is a 3-pole IEC molded-case circuit breaker on a 160 A frame, rated for 85 kA interrupting capacity at 415 V AC — class H breaking capacity. That means it clears high fault currents without cascading upstream, sized for main or large feeder protection in industrial panels. The ETU320 LI electronic trip unit gives adjustable overload protection (Ir = 40 A to 100 A) and short-circuit pickup (Ii = 1.5 to 12 x In), so you dial in the exact protection curve for your transformer or cable run.
Built-in accessories
This variant ships with an undervoltage release rated 208-230 V AC 50/60 Hz and two auxiliary switches (changeover contacts). The UVR trips the breaker when control voltage drops, preventing automatic reclosure after a sag — standard for safety circuits on conveyors or pumps. Auxiliary switches provide status feedback to the PLC or annunciator panel. All factory-fitted, no field wiring of add-on modules.
