Product description

The Siemens 3RV1021-0JA10-0KV0 is a Size S0 circuit breaker for motor protection, classified under Class 10 for thermal overload. It features an adjustable A-release range of 0.7 to 1 A and an N-release (short-circuit) of 13 A. This specific variant is a VW-Variant, indicated by the '-0KV0' suffix, implying a turned orientation of the screw connection (180 degrees). It uses screw terminals for connection. This part is phased out, with the SIRIUS 3RV2 series being its successor.
