The Siemens 3UG4622-1AW30 is a 1-phase current monitoring relay designed for precise detection of overcurrent and undercurrent conditions. It supports a sensing range from 0.05 A to 10 A, with adjustable time delays from 0.1 to 20 s and operates from 20.4 to 264 V AC/DC. Capable of DIN-rail mounting, its compact footprint (91 × 22.5 × 92 mm) and SPDT contact (3 A @ 400 V AC) make it ideal for control panels, protection circuits, and industrial automation environments.
You should choose this relay for its flexible current sensing range, adjustable timing, and robust SPDT contact configuration. Its ability to monitor both overcurrent and undercurrent states makes it a versatile protection and control component in automation systems.
