This Siemens 3VA5111-4EC36-1AA0 is a 3-pole molded-case circuit breaker designed for system protection. It features an operational current rating of 110A at 40°C, with a derated capacity at higher temperatures. The breaker operates at a rated voltage of 690V AC and provides a breaking capacity of 25kA at 480V, with other ratings available at different voltages.
The overcurrent release is of type TM230 with LI protection function, offering overload protection set at 110A and fixed short-circuit protection adjustable from 5 to 10 times the rated current. It is designed for HACR Type applications according to UL 489.
With a mechanical service life of typically 20,000 switching cycles and electrical endurance ratings varying by voltage and AC-1 conditions, this circuit breaker is built for reliability. It is mounted on a DIN rail and features a lever actuator. The maximum power loss is 25.8W, with an active power loss per pole of 8.6W under hot operating conditions.
Compliance includes UL489, VDE, CE, and CCC approvals. The RoHS status is RoHS3 Compliant, MSL is 1, and REACH status is Unaffected, though these compliance details are based on existing database information and may require verification.
