The Siemens 3RV20110JA15 is a robust circuit breaker from the SIRIUS 3RV2 series, specifically engineered for motor protection applications. This device features a size S00 frame and operates with a 3-pole main circuit configuration.
Key electrical specifications include an adjustable current response value for overload protection ranging from 0.7 to 1 Ampere, and a nominal operational current of 1A at 400V for both AC-3 and AC-3e applications. The breaker is rated for a maximum operating voltage of 690V and has a breaking capacity of 100 kA at 240V AC. It includes a thermal overload release and supports phase failure detection.
This circuit breaker is designed for DIN rail mounting and comes with transverse auxiliary switches, providing 1 normally open (NO) and 1 normally closed (NC) contact. It operates within an ambient temperature range of -20 to +60 °C and meets ATEX directive requirements.
With a mechanical and electrical endurance of 100,000 switching cycles, the 3RV20110JA15 is built for reliability in demanding industrial environments.
