B255XCXP-120VAC

**255 Series - Industrial Latching Relays** 3PDT or 4PST, 10 Amp 

File No. E13224 

The 255 Series is a two coil latching version of the general purpose type 219 relay. When the operate coil is momentarily energized, contacts transfer and remain so even after coil power is removed. The second coil when momentarily energized, provides electrical reset of the contacts. There is an optional manual reset actuator. All contacts operate from a common armature to prevent contact overlapping. Coils are rated for continuous duty. Both coils can be energized at the same time with no damage. The operate coil is dominant.
