Schneider Electric 8501RSD24V53 Miniature GP Relay

Schneider Electric's Square D 8501RSD24V53 Miniature GP Relay is a plug‑in, Type R general‑purpose relay with a 24 VDC coil and four Form C contacts (4PDT) arranged on a 14‑blade footprint. The device provides four independent poles, each with a normally open and a normally closed contact (4 NO, 4 NC) for simultaneous switching of multiple circuits from a single coil. It is rated for up to 0.167 horsepower at 120 VAC and 3 A resistive at 277 VAC, enabling control of small to medium loads in panel installations. The compact plug‑in relay is designed for quick replacement in compatible Square D/Schneider Electric enclosures, and the four‑pole arrangement supports complex logic, interlocking, and sequencing tasks in industrial control, automation, and equipment control applications. Its 24 VDC coil makes it suitable for low‑voltage control circuits in machine panels, HVAC controllers, and process automation where space is at a premium and multiple circuits need synchronized switching.
