Rapid and Reliable Phase Protection

Experience immediate safeguarding of your three-phase equipment, as this relay detects phase failure, incorrect sequence, and unbalanced conditions within 200 milliseconds. Built for industrial reliability, its robust electromagnetic design ensures continuous protection to prevent costly downtime or equipment damage.

User-Friendly Installation and Maintenance

Install effortlessly with the standard DIN rail mount and clear supply terminals (L1, L2, L3, N). The white-and-black enclosure not only looks modern but also aids in easy identification during maintenance. Low power consumption and durable contacts (1 C/O, silver alloy) make it a practical choice for long-term use.

FAQs of Phase Failure Relay:

Q: How does this phase failure relay enhance equipment safety?

A: The relay continuously monitors the power supply for phase failure, incorrect phase sequence, and unbalanced voltage. If it detects any abnormality, it disconnects your equipment within 200ms, minimizing potential damage and ensuring operational safety.

Q: What is the process for installing the relay in my system?

A: Simply connect the supply terminals to L1, L2, L3, and N, then mount the device onto a standard DIN rail. Its compact design and clear labeling facilitate quick and correct installation without the need for elaborate tools.

Q: When should I use a phase failure relay like this model?

A: This relay is essential for any three-phase system where motor protection, control panels, or sensitive equipment could be compromised by phase loss, sequence errors, or voltage unbalance. It is particularly valuable in industrial facilities and manufacturing plants.

Q: Where can this relay be installed for optimal performance?

A: Install the relay in control panels or distribution boards on a standard DIN rail, ensuring its close to the equipment or circuit requiring protection for the best response and ease of maintenance.

Q: What benefits does the relays high mechanical life offer?

A: With a mechanical life of up to 10,000,000 operations, the relay provides lasting performance, reducing the frequency of replacement and maintenance while keeping your system reliably protected over years of service.

Q: How can I verify the relays operational status?

A: Check for status indicators on the relay body or observe the connected equipments operation. For technical assurance, you may also check insulation and dielectric strength periodically, as specified in its technical parameters.
