Square D 8501XO40XTE1V02 Time Delay Relay 120VAC

Product Description

The SQUARE D 8501XO40XTE1V02 is a time delay relay designed for industrial and commercial control circuits that require a timed delay before energizing a load. Rated for 110 VAC at 50 Hz and 120 VAC at 60 Hz, this relay uses a Delay On Make timing function with a minimum delay of 0.2 seconds. Contact amperage is rated at 10 amps. It is installed by licensed electricians and industrial control technicians in panel-mounted or DIN-rail control systems where sequenced or time-delayed switching is required.

This relay is suited for commercial and industrial applications where a controlled time delay between a trigger signal and load activation is needed. Typical installations include motor control panels, HVAC equipment sequencing circuits, and automated process control systems. The Delay On Make function means the output contact closes after the set delay period elapses following the input signal, making it appropriate for staggered equipment startup and load management applications.

Key Features

• Delay On Make timer function for sequenced or staggered load activation
• Dual-voltage rating: 110 VAC at 50 Hz and 120 VAC at 60 Hz
• 10-amp contact rating for reliable switching in control circuits
• Minimum delay setting of 0.2 seconds for precise timing control
• Compact form factor suited for panel or enclosure mounting

Compatibility

Designed as an OEM-style replacement time delay relay for commercial and industrial control panel applications requiring Delay On Make functionality at 120 VAC.

Installation Notes

Installation should be performed by a qualified electrician in accordance with the NEC and applicable local codes. De-energize and lockout the control panel before removing or installing any relay. Verify that supply voltage and frequency match the relay rating before energizing. Ensure all wiring connections are secure and the enclosure is properly closed before restoring power.
