Siemens Starter, Fail-Safe Function, Solid-State Overload Protection - SIRIUS Series - 3RM1107-1AA04 Get machine processes safely underway with this starter from Siemens. As a direct-type device, it links your line voltage to your motor and uses solid-state overload protection to make sure it turns on and off reliably. To keep operations up and running, it's fitted with hybrid switching technology. A wear-resistant semiconductor starts and stops your motors, while a low-energy relay keeps things rolling without generating excess heat. This efficiently minimises your power losses to 3.4W. The unit has a width of 22.5mm to fit into compact cabinets and it snaps onto standard 35mm rails for easy mounting. You can use it to control small motors in machine tools, manufacturing machines and conveyors. Features & Benefits • Dial sets your overload release level between 1.6 and 7A to match your motor's needs
• Suitable for mounting vertically and horizontally for installation flexibility
• Mechanical service life of 30 million cycles ensures it's long-lasting
• Handy button on the front for resetting and testing
• LEDs for swift status and error checks Does this starter have fail-safe functionality? Yes. The component's fail-safe function means you can combine with 3SK-series relays (such as 183-7198) to build a disconnection system. This means you can automatically shut off motors when barriers and gates are open, for example.
