Siemens 3UG5 Series Monitoring Relay, 120/690V AC Supply Voltage, 0.1 to 30s Time Delay - 3UG5616-2CR20


This monitoring relay monitors three-phase supply conditions and protects equipment against phase sequence errors and phase loss in industrial control systems. It is intended for DIN-rail installation in control panels and performs continuous supervision of a 3-phase network with an adjustable response timing to suit motor and automation protection needs.

Features and Benefits:


• DPDT contacts provide versatile switching for control circuits
• 120/690V AC supply range supports varied industrial voltages
• Adjustable time delay 0.1–30s allows tailored response timing
• Spring‑loaded terminals enable fast, secure wiring connections
• IP20‑rated enclosure suits protected indoor control cabinets
• Operating temperature range -25°C to 60°C maintains function across environments

Applications


• Suitable for phase sequence detection in motor starters
• Ideal for preventing equipment run‑on after phase loss
• Used with PLCs for upstream supply supervision tasks
• Can be used for three‑phase motor protection in distribution panels

How is the device mounted within a control cabinet?


It clips onto a standard DIN rail for rapid, tool‑free installation and alignment with other modular control devices.

What contact arrangement is available for switching control circuits?


The unit provides a double‑throw contact configuration enabling simultaneous make/break of two separate circuits.

Which standards does it comply with for electrical safety testing?


It meets recognised international approvals relevant to industrial electrical insulation and certification protocols used in professional installations.

How Compact is the product for high‑density panel layouts?


The design occupies a slim 22.5mm width to conserve rail space while allowing multiple units to be mounted side‑by‑side.

What phase conditions does it monitor and respond to?


It supervises three‑phase presence, phase sequence and loss, initiating a timed output when detected anomalies exceed the set delay.
