Siemens 3RV2031-4PA10 Motor Starter Protector S2 Class 10 28-36A

The Siemens 3RV2031-4PA10 is a SIRIUS 3RV2 circuit breaker for motor protection, designed to provide reliable overload and short-circuit protection for industrial motors and equipment. This Class 10 device features an adjustable trip range of 28-36 amperes, making it ideal for protecting medium-sized three-phase motors in industrial applications.

Key Features:

• Adjustable trip current range: 28-36A for precise motor protection
• Class 10 trip characteristic for standard motor starting applications
• S2 frame size for compact installation in control panels
• Screw-type terminals for secure, reliable wire connections
• Thermal overload and magnetic short-circuit protection in one device
• Manual reset button with lockout capability
• Trip-free mechanism prevents manual override during fault conditions
• Auxiliary contact capability for remote status monitoring (contacts sold separately)

The 3RV2 series motor starter protectors combine a circuit breaker and overload relay in a single, space-saving unit. The Class 10 tripping characteristic allows the motor to draw locked-rotor current for approximately 10 seconds before tripping, accommodating typical motor starting conditions. These devices are UL listed, CSA certified, and meet IEC standards for international applications.

Ideal for use in manufacturing equipment, conveyors, pumps, fans, compressors, and other industrial machinery requiring reliable motor circuit protection. The screw terminals accept conductors up to 10 AWG and provide vibration-resistant connections suitable for demanding industrial environments.
