Struthers-Dunn B255XCXP High Current Power Relay

Struthers-Dunn B255XCXP is a high-current, two-coil, mechanical latching power relay from the 255 Series that delivers three-pole, double-throw (3PDT) switching. Available in both AC-latch and DC-latch configurations, this model family includes coil-voltage options such as 115/125 VDC and 120 VAC, enabling flexible control of the load from either DC or AC sources. The relay uses two coils to set and reset its latch, allowing it to retain its contact state without continuous coil power, which is advantageous for energy efficiency in applications that require state retention between drive pulses. The 3PDT contact arrangement provides three independent poles, each with normally open and normally closed contacts, suitable for multi-line switching in industrial controls and power-management circuits. As part of Struthers-Dunn’s robust line of relays, the B255XCXP is designed for demanding, high-current switching and is commonly used in control panels and equipment where reliable, long-term latching operation is essential.
