Product Details
The Polarized Rib Series is equivalent to the standard Rib Series except for the coil, which is polarized. This series includes nine polarized relays, most of which have a similar non-polarized counterpart. The "FA" in the model name signifies Fire Alarm. These relays are designed for operation in systems requiring supervision from controllers and utilize end-of-line resistors. Additionally, the relay can operate from A/C voltage (non-polarized) if desired.
