Siemens Monitoring Relay, AC Voltage Type, 3 Poles - SIRIUS Series - 3UG4615-1CR20

Keeping an eye on the AC supply in your motor circuit is easy with this monitoring relay from Siemens. Thanks to a wide voltage range of 160 to 690V AC, this handy gadget means you don't need multiple devices for different power levels. Plus, since the response time is adjustable between 0.1 and 20 seconds, it's sensitive enough to keep your equipment safe while minimising downtime from nuisance trips. Thanks to a crystal-clear LCD display, information detailing values and fault types is available at a glance. You'll find relays like this used in industrial electrical installations for monitoring residual current, insulation and power levels.

Features & Benefits

• Straightforward snap-on mounting makes installation quick and easy
• Monitors both undervoltage and overvoltage for protection you can rely on
• 450ms maximum response time helps prevent damage in the event of a problem
• IP20 rating means it's touch-proof for added user safety

What fault conditions can this monitoring relay detect?

To help keep your 3-phase motors in peak condition, this unit detects both over-voltage and under-voltage, as well as phase failure and asymmetry. You can also use it for 3-phase voltage window recognition.
