Product Positioning

The 3UG4622-2AW30 is a Siemens SIRIUS current monitoring relay with a spring-loaded terminal design, capable of monitoring single-phase overcurrent and undercurrent conditions within the range of 0.05 to 15A.

Core Product Advantages and Features

Spring-loaded quick-connect terminal blocks

The use of spring clip (detachable) terminals allows for quick wiring without the need for screws, shortening installation time.

General-purpose control power supply

The control power supply voltage covers 24 to 240V AC/DC, 50/60Hz, and a single model is suitable for a variety of power supply environments.

Two-way monitoring of overcurrent and undercurrent

The overcurrent and undercurrent action values can be set simultaneously, and the hysteresis range is adjustable from 0.01 to 5A to avoid frequent contact jumps.

Adjustable delay time

Both startup delay and action delay can be adjusted between 0.1 and 20 seconds to suit different load startup characteristics.
