Siemens 10 → 16 A SIRIUS Motor Protection Circuit Breaker, 20 → 690 V

Carefully monitor operating currents and respond quickly to disturbances and surges with this Siemens circuit breaker. It offers excellent protection for 3-phase motors with its class-10 tripping function, which means the breaker will trip in 10 seconds or less at six times the maximum thermal current rating. Thanks to this quick response time, you can rely on the unit to enhance safety and minimise damage to motors and other connected components. It's possible to combine this component with accessories such as lateral and transverse auxiliary switches, undervoltage releases and shunt releases for greater flexibility.

• Current rating of 11 to 16A (amperes) for standard use
• Spring-loaded terminals for quick and simple installation
• Magnetic short-circuit trip design provides reliable action

This unit can be screwed on or snapped onto a standard 35mm DIN rail. The compact design with a width of 45mm allows for placement in limited spaces.

The Siemens Sirius Innovation modular system is a range of compatible connection modules, contacts, overload relays and related components that work together in a fully integrated operating system.
