Siemens AG 3RV2011-1GA10 Thermal Overload Relay

Siemens 3RV2011-1GA10 is a three-pole motor protection circuit breaker with an integrated thermal overload release in the S00 size from the SIRIUS 3RV2 family, designed to protect small motors. The thermal overload element is adjustable in the range of 4.5 to 6.3 A, providing Class 10 thermal protection to minimize damage from overloads. The unit is rated for operation up to 690 V and delivers motor protection with short-circuit protection in a compact, screw-terminal enclosure with front IP20 protection. It supports ambient operating temperatures from -20 to +60 C and installation at elevations up to 2000 meters above sea level. This 3-pole device is used in motor control circuits to safeguard equipment such as pumps, fans, and conveyors, working alongside standard contactors to provide integrated protection without additional thermal relays. Its labeling and specifications align with Siemens documentation for 3RV2011-1GA10, including the 4.5–6.3 A overload setting and CLASS 10 trip classification.
