Product description

The Siemens 3UG4815-1AA40 is a digital monitoring relay designed for monitoring 3-phase line voltage, featuring IO-Link communication. It operates within a voltage range of 3 x 160 to 690 V AC and monitors for phase sequence, phase failure, phase asymmetry, undervoltage, and overvoltage. The relay includes adjustable hysteresis for voltage (1-20 V) and line stabilization delay, with a tripping delay. It is equipped with 1 changeover contact and screw terminals.

This relay is essential for protecting 3-phase equipment from voltage-related issues in industrial settings such as manufacturing plants, pumping stations, and HVAC systems. Its IO-Link capability allows for advanced diagnostics and integration into smart factory environments.

Stanlo Automation, a veteran-owned surplus parts distributor, offers the Siemens 3UG4815-1AA40. Secure reliable industrial automation components from a trusted source committed to quality and value.
