Struthers-Dunn B255BXBPLM is a 255 Series two-coil, mechanically latching relay rated for 120 VAC operation at 50/60 Hz. It uses a DPST-N.O. plus DPST-N.C. contact configuration (four-form) in a plug-in 12‑pin package, featuring a polycarbonate cover and a blowout magnet. The model includes an on-board pilot lamp and a manual reset option, with a 120 VAC coil. It is rated to switch motor loads up to 1/6 HP at 120 VAC, making it suitable for compact control circuits where a latched state is maintained until a reset signal is applied.
