Power relay

The selection starts by checking the key parameters provided. This model works at 230 V ±10% and 50/60 Hz and supports up to 60 A with a maximum load of 8.8 kVA, making it suitable for home circuits and small workshops. It includes overvoltage cutoff ( 270 VAC ±5 V) and undervoltage cutoff ( 170 VAC ±5 V), and it recovers in less than one second. It mounts on a 35 mm DIN rail and consumes less than 2 W. Its white plastic housing and dimensions make it easy to install in an electrical enclosure. The package includes 1 protection unit.

The exact cutoff thresholds are overvoltage 270 VAC ±5 V and undervoltage 170 VAC ±5 V, which triggers a fast cutoff to prevent damage. The device can carry a maximum load of 60 A and a useful power of 8.8 kVA, providing robust protection for your home network. The cutoff time is very short, and it restores operation as soon as the voltage returns to the normal range. This responsiveness helps protect sensitive equipment and power supplies.

This device is designed for home use and simple workshop or compact electrical cabinet installations. Its 35 mm DIN rail mounting and white plastic housing make it easy to integrate into household wall enclosures. It provides effective automatic protection without needing external power, making it practical for systems where voltage stability is a common concern.

Check these key points: compatibility with a 35 mm DIN rail and the exact dimensions (35L x 70W x 77H mm here), material (plastic) and color (white), nominal voltage and range (230 V ±10%), maximum current (60 A), and power (8.8 kVA). Also ensure the product includes the over/undervoltage protection unit and that it consumes very little in standby mode (≤2 W). Finally, confirm the installation is appropriate for your electrical panel.

It protects against voltage variations that could damage equipment and cause failures. By detecting voltage deviations quickly, it cuts off power and then automatically restores it when voltage returns to the normal range. This minimizes interruptions and reduces wear on sensitive components. For devices like power supplies, computer systems, and small motors, this level of protection can extend their lifespan and reduce maintenance costs.

Installation is easy: fix the unit on a 35 mm DIN rail, then connect the wires according to the provided wiring diagrams. Make sure the voltage and expected loads match its specifications. If you’re unsure, contact a qualified electrician. For troubleshooting, check the mounting condition, verify wire continuity, and ensure the housing stays dry and protected. If the problem persists, contact the seller for technical guidance.
