Product Positioning

The 3RU2116-1GB1 is a Siemens SIRIUS 3RU2 series S00 frame thermal overload relay with an adjustable current range of 4.5 to 6.3 amps. It features screw terminals and an independent mounting design, providing motor overload and phase loss protection.

Core Product Advantages and Features

Adjustable current range

The set current can be adjusted between 4.5 and 6.3 amps, finely adjusted according to the actual rated current of the motor, providing accurate overload trip protection.

Terminal type

This model uses screw terminals (identified by the original B/C tail code) to facilitate wiring and ensure stable contact.

Installation method

This model is designed for independent installation (not directly mounted on the contactor), and the installation method differs from the original manufacturer's 0/1 tail code, facilitating the configuration and planning of the distribution box.

Detachment from levels and contacts

It features a Class 10 tripping rating and 1 NO + 1 NC auxiliary contact, allowing for manual or automatic reset. It is suitable for use with an S00 size 3RT contactor to form a motor starting circuit.
