Siemens PM17AY-120V Power Relay

Siemens PM-17AY-120V Power Relay is a heavy‑duty PM Series open‑style relay that consolidates four switching circuits in one compact unit. It is a 4PDT (four‑pole, double‑throw) power relay with a 120 VAC coil, designed to drive loads up to 35 A at voltages up to 240 VAC. The coil consumes about 18 VA, enabling reliable actuation from typical control circuits, and the unit is commonly offered in a socket version for quick installation in control panels. Constructed with silver‑cadmium oxide alloy contacts, it provides robust electrical life for high‑current switching tasks. The PM‑17AY‑120 variant is tailored to 120 VAC coil operation, making it suitable for industrial automation, motor control circuits, and power distribution applications where multiple circuits require synchronized switching. This configuration's open‑style enclosure and available socket mounting simplify maintenance and replacement, while its durable construction supports repeated cycling in demanding environments.
