FAQ
Q1. What is the difference between SPP-22 and V22-RYB?
SPP-22 provides electrical protection by tripping during phase faults, while V22-RYB is a visual indicator showing phase availability and sequence.
Q2. Can both devices be installed in the same panel?
Yes, they are compact and designed for DIN-rail or panel mounting, making them suitable for combined installation.
Q3. Does SPP-22 support automatic reset?
Yes, the relay auto-resets once normal phase conditions return.
Q4. What voltage is required to operate the combo?
Both devices work on a 280–500V AC (L-L) three-phase supply.
Q5. Is this combo suitable for motor panels and pumps?
Absolutely. It helps prevent motor burnouts caused by phase loss, reverse sequence, or imbalance.
Q6. Does the V22-RYB show an incorrect phase sequence?
It visually highlights correct phase availability, helping in diagnosing reverse sequence when paired with SPP-22.
