Siemens 3.5 → 5 A SIRIUS 3RV Motor Protection Circuit Breaker, 20 → 690 V

For reliable motor protection, opt for this 5-amp circuit breaker from Siemens. It's fitted with a state-of-the-art current monitoring relay located directly in the main circuit, as well as phase disturbance recognition for faster response times. As part of the Sirius Innovation modular system, the unit is designed to work with other items in the range. You can combine it with SIRIUS soft starters for a torque-restricting and current-limiting startup process that's both safe and efficient. It screws and snaps onto a standard DIN rail, and with a width of just 45mm, it can fit into units where space is tight.

• Current rating of 3.5 to 5A for standard use
• Spring-loaded terminals provide an easy connection to the main current circuit
• Thermomagnetic design of both overcurrent release and short-circuit release for dependable reliability

Class 10 tripping means that at six times the maximum thermal current rating, the breaker will trip in 10 seconds or less. This quick response time improves safety and limits damage to motors and connected components.
