Struthers-Dunn PM-17AY-240 Relay

Struthers-Dunn PM-17AY-240 is an open-style PM Series power relay with four independently switching poles (4PDT) in a single package, designed for high-current control in industrial panels. It uses a 240 VAC coil and is rated to switch up to 35 A at 240 VAC across all four contacts, with the contacts also capable of handling DC loads up to 28 VDC; the nominal coil resistance is approximately 587 ohms. Terminals are standard screw terminals (#M4), and a dust-cover accessory is available for additional protection in dirty environments. Typical applications include motor control, power distribution, and interlocking or sequencing tasks in automation systems.
