Square D 8501XO40XLV02 General Purpose Relay 10A 4NO

Product Description

The SQUARE D 8501XO40XLV02 is an electromechanical general purpose relay with a screw clamp terminal design, built for reliable switching in industrial and commercial control circuits. It carries a 10 amp rating at 600 VAC and features a 4NO (four normally open) contact form. Coil voltage is rated at 110 VAC at 50 Hz and 120 VAC at 60 Hz, making it compatible with standard North American and international supply voltages. Licensed electricians and controls technicians install this relay in machine control panels, motor starter circuits, and automated process equipment where dependable switching and secure terminations are required.

This relay is suited for use in light industrial, commercial, and OEM machine control applications. The screw clamp terminals provide a secure, vibration-resistant connection appropriate for panel-mount installations where wire loosening over time is a concern. It is commonly installed in control cabinets, relay panels, and equipment enclosures where general purpose switching of pilot loads, contactors, or auxiliary circuits is needed. The 10 amp contact rating accommodates a wide range of resistive and inductive loads typical in control applications.

Key Features

• 10 amp contact rating at 600 VAC for versatile load switching
• 4NO contact form provides four independent normally open switching poles
• Screw clamp terminals ensure secure, vibration-resistant wire connections
• Dual coil voltage rating: 110 VAC at 50 Hz and 120 VAC at 60 Hz
• Certified to CE, CSA, UL, and RoHS standards for broad application compliance

Compatibility

Designed as an OEM-style replacement for general purpose electromechanical relays used in industrial and commercial control panel applications requiring a 4NO screw clamp relay at 10 amps and 600 VAC.

Installation Notes

Installation should be performed by a licensed electrician in accordance with the National Electrical Code (NEC) and any applicable local codes. De-energize and lock out the control panel before removing or installing the relay. Confirm coil voltage at the circuit matches the relay rating before energizing. Tighten screw clamp terminals to the torque range specified in the panel wiring documentation to ensure proper connection integrity.
