Siemens 3UG4 Series Monitoring Relay, 24 to 240V Supply Voltage, 0.1 to 20s Time Delay - 3UG4625-1CW30

This monitoring relay monitors residual and phase overcurrent in AC/DC systems and provides configurable warning and trip thresholds. It operates from a broad supply range and features an LCD for indication and an error memory for event recording. Designed for DIN‑rail installation, it is suitable for industrial control panels where adjustable detection and timed responses to current anomalies are required.

Features and Benefits:

• Measures from 10 mA to 43 A for precise current sensing
• Dual adjustable thresholds for warning and trip functionality
• Time delay adjustable 0.1 to 20 s for tailored response timing
• Two changeover contacts provide 5 A switching capacity
• Screw terminals enable secure connections and easy wiring

Applications

• Suitable for residual current monitoring with CTs
• Used with motor control circuits for overcurrent signalling
• Ideal for industrial panels requiring DIN‑rail mounting
• Can be used for safety surveillance in distribution boards

What supply voltages will it accept?

It accepts AC or DC supply from 24 to 240 V with 50/60 Hz compatibility.

How accurate is the current measurement?

The device shows relative metering precision of 5% and relative repeat accuracy of 1%.

How does it behave after a power interruption?

It offers a minimum buffering time of 10 MS to retain short‑term signalling during supply loss.

What environmental conditions can it operate in?

It is rated for operation from -25 °C to +60 °C and at altitudes up to 2,000 m.

What protection and approvals does it hold?

It carries IP20 enclosure protection and approvals including CE, UL, RoHS, RCM and EAC.
