Siemens 3RV1011-1JA10 Molded Case Circuit Breaker

Siemens 3RV1011-1JA10 is a three‑pole motor‑protection molded‑case circuit breaker (MCCB) in size S00, intended for DIN‑rail mounting in industrial control panels. It protects three‑phase motors from overload and short‑circuit events in 220–690 VAC systems, with an adjustable A‑release thermal/magnetic trip settable from 7 to 10 A and a fixed N‑release up to 130 A for rapid fault isolation, and it is suitable for motors up to about 4 kW in typical applications. The device uses screw terminals for main connections, provides IP20 protection, and supports up to 690 V insulation with 6 kV surge withstand; auxiliary switch capability is available for control circuits, and its standard switching capacity is designed for repeated motor protection cycles. Designed for reliable duty with long electrical and mechanical life, it offers around 100,000 switching cycles and remains a compact, code‑compliant solution for pumps, fans, conveyors, and other motor‑driven equipment where compact protection and easy control integration are essential.
