Siemens 3RV1011-1GA15 Motor Protection Switch

Siemens 3RV1011-1GA15 is a compact S00‑size motor protection circuit‑breaker from the SIRIUS 3RV1 family, designed to protect small motors against overload and short circuits while providing a built‑in disconnect for safe isolation in control panels. It carries Class 10 thermal‑trip characteristics with an A‑release setting of 4.5–6.3 A and a N‑release of 82 A, and it uses screw terminals for dependable wiring. The unit includes a transverse auxiliary switch (1 NO + 1 NC) for interlocking or signaling in control circuits and offers standard switching capacity suitable for motor circuits rated up to 690 V (insulation voltage 690 V) with surge resistance of 6 kV. With an endurance rating of about 500 switching cycles, this device is intended for AC‑3 duty in motor protection applications, and it is commonly used in machine control panels and motor starters to provide both overload protection and a disconnect function.
