Siemens 3VA1132-6EF36-0KC0 — IEC Frame 160, 70kA Class H
The Siemens 3VA1132-6EF36-0KC0 is a 3-pole IEC circuit breaker from the 3VA1 series, built on a 160 A frame with breaking capacity class H — meaning it can interrupt 70 kA at 415 V AC without damage. That Icu rating places it in the high-break category for industrial distribution panels where fault currents are substantial, such as transformer secondaries or motor control center mains. Rated at In=32 A with a TM240 thermal-magnetic trip unit, the overload protection (Ir) is adjustable from 22 A to 32 A, and the instantaneous short-circuit pickup (Ii) is set at 5 to 10 times In. That adjustability lets you coordinate with downstream branch breakers or motor starters without swapping the entire device — useful for panel builders who need selectivity without oversizing.
Auxiliaries and Trip Accessories
This unit ships with a shunt trip (STL) rated for 220–250 V DC or 208–277 V AC, plus two HQ auxiliary switches for remote status indication. The shunt trip allows emergency-off or remote-trip integration into a safety circuit or PLC-driven shutdown sequence. Clamp-type connections simplify panel wiring — no lug crimping needed for the main power terminals.
