Square D 9050JCK18V20 Dpdt Time Delay Relay 0.66 Min

Product Description

The SQUARE D 9050JCK18V20 is a DPDT (double-pole, double-throw) time delay relay with a Delay On Make timer function and a fixed delay interval of 0.66 minutes. The relay switches at 10 amps contact rating and operates on 120 VAC or 110 VDC control voltage, making it suitable for a range of industrial and commercial control circuit applications. Licensed electricians and controls technicians install this relay into timing circuits where a controlled delay before load energization is required. Its compact form factor fits into standard relay sockets used in control panels and equipment enclosures.

This time delay relay is used in industrial control panels, HVAC equipment, commercial refrigeration, and process control systems where a Delay On Make function is needed. It is designed for applications requiring a timed pause before a load or downstream circuit is activated. The 0.66-minute fixed delay suits sequences where a brief, consistent hold-off period protects equipment or coordinates multi-stage operation. Both AC and DC control voltage compatibility adds flexibility across different panel designs.

Key Features

• DPDT contact configuration rated at 10 amps
• Dual control voltage compatibility: 120 VAC and 110 VDC
• Compact housing measuring 4.2 inches long by 2 inches wide by 2.4 inches tall
• Drop-in replacement format for standard relay socket mounting

Compatibility

Designed as an OEM-style replacement time delay relay for industrial and commercial control panel applications requiring DPDT Delay On Make functionality at 120 VAC or 110 VDC control voltage.

Installation Notes

Installation should be performed by a licensed electrician or qualified controls technician. De-energize and lock out the control panel before removing or installing the relay, following applicable NFPA 70E safe work practices. Verify that the socket wiring matches the relay contact configuration before applying power. Do not exceed the 10-amp contact rating for any switched load.
