Product Positioning

The 3RV2011-0GA20 is a Siemens SIRIUS series S00 frame motor protection circuit breaker. The thermal overload current can be adjusted within the range of 0.45–0.63A, and it has a built-in instantaneous short-circuit trip (N trip 8.2A), making it suitable as the main protection element for three-phase motor circuits.

Core Product Advantages and Features
Adjustable thermal overload protection
The rotary dial allows for precise setting of the motor's rated current within the range of 0.45–0.63A, adjusting according to the actual load to reduce the risk of false tripping and insufficient protection.
Instantaneous short circuit and rapid disconnection
It features a built-in magnetic instantaneous short-circuit trip with an operating current of 8.2A. In the event of a short circuit, it can quickly disconnect the faulty circuit and protect downstream lines and equipment.
S00 miniaturized design
With a CLASS 10 operating level and a streamlined S00 housing, it is suitable for control boxes and panels with limited space and can be quickly installed with a 35mm DIN rail.
Built-in auxiliary contact feedback
The standard configuration includes 1NO+1NC auxiliary switches, which can directly feed back the circuit breaker status to the PLC or control circuit for easy monitoring and interlocking.
Spring-loaded screwless terminals
The design features spring-loaded (screwless) terminals, ensuring quick and secure wiring and reducing poor contact caused by loose terminals over long-term use.
