Siemens Circuit breaker for motor protection, screw, size S00, 8.2A Part number 3RV1011-0GA10

Product Overview

The Siemens 3RV1011-0GA10 is the Siemens SIRIUS 3RV10 Motor Protection Circuit Breaker, size S00 (0.45–0.63 A). It is designed to protect motors and low-current loads against overloads, short-circuits and phase failures — ideal for small motor circuits, control panels, or feeder circuits requiring reliable protection in a compact footprint.

Key Features

• Compact motor-protection circuit breaker (SIRIUS 3RV1 / 3RV10 series, size S00)
• Adjustable thermal overload release range: 0.45 … 0.63 A
• Three-pole main contacts for three-phase circuits
• Thermal + magnetic (short-circuit) protection built in
• High short-circuit breaking capacity: up to 100 kA (AC, up to 690 V)
• Screw-terminal connections — secure wiring even under vibration
• DIN-rail (35 mm) or screw mounting — easy installation in distribution or control panels
• Compact dimensions and light weight — suitable for space-constrained panels or retrofit setups
• Manual reset and lockable OFF position — suitable for safety / maintenance applications
