Siemens 9 → 12 A SIRIUS 3RV Motor Protection Circuit Breaker, 690 V ac

Catch common faults before they reach your motor-driven system with this motor protection circuit breaker from Siemens. Its thermomagnetic trip mechanism breaks the attached circuit when it receives overcurrent or excessive torque, reacting to problems as soon as they crop up. With an adjustable current setting between 9 and 12.5A, the unit flexes to fit its power supply for versatile protection. Mounting is done in no time, as it simply clips onto a DIN rail. By stopping short-circuit current up to 100kA, this device shuts down heavy overloads without a snag. Circuit breakers like this are essential bits of kit in manufacturing setups and the automotive industry.

• Trips up to 15 times an hour to handle demanding applications
• Selector switch reset ensures speedy restart after tripping
• Spring-loaded terminals keep a tight hold on conductors if there's movement
• Low power loss of 7W for energy-efficient protection
• Safe for use in a wide temperature range between -20°C and +60°C

This unit lasts for around 100,000 mechanical cycles, so it's a reliable component for long-lasting motor protection.
