Siemens Circuit breaker for motor protection, size S00, 0.8/10A

Product Overview

The Siemens 3RV2011-0HA10 is a compact motor protection circuit breaker (motor starter protector) from the SIRIUS 3RV2 family, size S00. It provides thermal-magnetic overload and short-circuit protection for small motors and devices. The unit is built for three-phase circuits and is suitable for protecting motors or feeders against overload and phase-failure conditions, combining protective functions in one compact device.

Key Features

• Motor protection breaker (circuit-breaker) — size S00, SIRIUS 3RV2 series
• Thermal-magnetic overload protection — adjustable motor current setting in the range 0.55 … 0.8 A
• Three-pole main circuit (3-phase protection)
• Phase-failure detection (phase-loss sensitivity) for motor safety
• Compact design — suitable for control-panel DIN-rail mounting and small control cabinets
• Screw-terminal connections for main circuit and wiring flexibility
• Standard insulation/surge withstand: rated insulation 690 V, surge-voltage resistance up to 6 kV — suitable for industrial environments with typical mains voltages
• Good mechanical and electrical durability — rated for many switching cycles under normal use

Applications

The 3RV2011-0HA10 is used to protect small motors or control circuits from overload, short-circuit, and phase-failure conditions. Typical applications include small pumps, fans, ventilation motors, small machinery, and control-panel motor circuits where a compact motor-protection device is required. It is especially suited for installations with limited space, where a compact, reliable motor protection breaker is needed rather than a full motor starter contactor + overload relay assembly.
