Frequently Asked Questions
- What does DPST-N/C mean in this relay?
Double Pole Single Throw – Normally Closed means both sets of contacts are closed when the coil is not energized. The circuit opens only when the coil is powered. - Why choose the -S-NC version over other models?
The RIB01P30-S-NC includes both normally closed contacts and a coil-side override switch for added manual control, making it ideal for fail-safe or emergency-off circuits. - Can it be used with electronic loads?
No. This relay is not rated for electronic ballasts or LED drivers. Use a relay specifically rated for those applications.
Installation Tips & Mistakes to Avoid
- Tip: Use the coil-side override switch during startup or troubleshooting for fast control testing.
- Tip: Clearly mark control wiring to avoid confusion with standard N/O models during installation.
- Mistake to Avoid: Don’t use this model with capacitive or high-inrush loads such as LED drivers or electronic ballasts.
- Mistake to Avoid: Ensure wiring reflects N/C contact behavior — incorrect logic can result in system faults or equipment staying on during power loss.
