The Siemens 3VA2612-5HL32-0KC0 is a 3-pole IEC frame 1250 molded-case circuit breaker from the 3VA2 series, fitted with an ETU320 electronic trip unit configured for LI (long-time and instantaneous) protection. The continuous current rating In = 1250 A, with overload pickup Ir adjustable from 500 A to 1250 A and instantaneous pickup Ii adjustable from 1.5 to 10 times In, so this single order code covers a wide range of cable and busbar protection settings without changing the breaker frame.
Integrated accessories and deployment context
The shunt trip allows remote tripping from a PLC or emergency-stop circuit — useful in motor control centers or distribution panels where a safety PLC needs to drop the main breaker on a fault signal. The 3VA2 frame is designed for IEC switchboards and can be fitted with rotary handles, motor operators, and communication modules (PROFIBUS, PROFINET, Modbus) as field-installable accessories.
