Stock Quantity: 0
The PLS2-40A is a single-pole double-throw (SPDT) Reverse Phase Relay manufactured by LITTELFUSE. This device is designed to detect reverse phase conditions in 208/240 VAC power systems. Upon detection of a phase reversal, the relay switches its output state, providing a signal for control or protection circuits. The PLS2-40A is commonly used in industrial and commercial electrical installations.
This reverse phase relay is typically utilized in three-phase power systems to safeguard equipment from damage caused by incorrect phase sequencing. Its reliable switching action makes it suitable for various protective functions.
