Struthers-Dunn 425BXX Relay

The Struthers-Dunn 425BXX is a three‑pole open‑style power relay designed to switch higher‑current loads in control panels and industrial equipment. It is rated to carry up to 30 A and handle up to 1 HP, with a DPST (two normally open) contact arrangement designated BXX and screw‑terminal wiring for easy installation. The 425BXX family offers coil options including 12 VDC (for example 425BXX204) and 120 VAC (as in 425BXX170), and its design provides spacing enough for up to 600 VAC contact ratings. The unit uses enclosed coils with silver alloy contacts by default and is UL Recognized and CSA listed, manufactured in the USA. This relay is well‑suited for general‑purpose power switching in automation panels, motor control circuits, and heater or similar line‑powered applications where reliable, rugged performance is needed.
