FAQs of Single Phasing Preventer:

Q: How does the Single Phasing Preventer protect electrical equipment?

A: The device detects phase failures, reversals, and unbalances by monitoring L1, L2, and L3 terminals. When an anomaly is detected, it immediately responds in less than 0.2 seconds by triggering a relay to isolate the connected load, helping prevent equipment damage.

Q: What benefits does the fast operate time of less than 0.2 seconds offer?

A: A rapid operate time ensures that any phase irregularity is addressed almost instantly, minimizing the window in which connected machinery or equipment could be exposed to damaging conditions. This enhances operational safety and equipment longevity.

Q: When should a Single Phasing Preventer be installed?

A: It should be installed wherever three-phase electrical equipment operates, particularly in industrial settings where uninterrupted phase protection is essential, such as with motors, pumps, or sensitive automated systems.

Q: Where is the product typically used?

A: This preventer is widely employed in industrial electrical panels, substations, and control cabinets, especially in sectors like manufacturing, water treatment, and HVAC systems within India and globally.

Q: What is the correct installation process for this device?

A: Connect the supply terminals to L1, L2, and L3 phases. Ensure the wiring and mounting align with safety standards and equipment manuals. Verify proper settings before powering up to guarantee optimal protection.

Q: How does the SPDT contact and silver alloy material improve relay performance?

A: The SPDT (Single Pole Double Throw) contact configuration allows versatile switching options, while silver alloy contacts provide low resistance (<100m) and excellent conductivity, leading to efficient, long-lasting performance.
