Siemens 3RV1021-0DA15 S0 Motor Protection Circuit Breaker
The Siemens 3RV1021-0DA15 is a Size S0 circuit breaker for motor protection, offering Class 10 thermal overload protection with an adjustable trip range of 0.22 to 0.32 A and a short-circuit release of 4.2 A. This unit includes a transverse auxiliary switch with 1 Normally Open (NO) and 1 Normally Closed (NC) contact, and uses screw terminals. It is a standard switching capacity, phased-out product, with the SIRIUS 3RV2 series, specifically the 3RV2011-0DA15, being its successor.
This circuit breaker is ideal for motor control applications where signaling of the breaker's status (e.g., tripped or closed) is required. Industries such as building automation, manufacturing, and water treatment utilize these in control panels for pumps, fans, and machinery requiring remote monitoring.
