Siemens Circuit breaker for motor protection, size S00, 1.4 - 2A (N) Part number 3RV1011-1BA10

Product Overview

The Siemens 3RV1011-1BA10 is a motor-protection circuit breaker from the SIRIUS 3RV1 series. It is designed to protect small motors against overload and short-circuit, combining adjustable thermal overload release and magnetic short-circuit protection in a compact S00-sized housing. The device is ideal for small motor feeders, compact machinery, or control-panel installations where motor protection and cost-effective reliability are required.

Key Features

• Motor-protection circuit breaker, SIRIUS 3RV1, size S00
• Thermal (overload) adjustable release setting: 1.4 … 2 A
• Magnetic (instantaneous) short-circuit release: 26 A
• Combined overload + short-circuit protection with single device — simplifies motor branch protection
• Screw-terminal connections — secure wiring suitable for panel/motor control wiring
• Compact size — suitable for small motors / compact motor starters
• Standard insulation voltage rating up to 690 V AC — suitable for typical industrial motor supply voltages

Applications

The 3RV1011-1BA10 is ideal for protecting small three-phase motors, pumps, fans, small compressors or auxiliary drives. It is especially useful for compact motor control cabinets, retrofit motor starters, small machinery, or any installation where space is limited but reliable motor protection is needed. Because of its adjustable overload setting, it can be tuned to the motor’s full-load current for optimal protection.
