Square D 9050JCK24V20 Dpdt Time Delay Relay

Product Description

The SQUARE D 9050JCK24V20 is a double-pole double-throw (DPDT) time delay relay designed for industrial and commercial control circuit applications. This relay functions on a delay-on-break timer function, meaning the output contacts remain energized for a set period after the control signal is removed. It is rated for 10 amps of contact current and operates on 110 VDC or 120 VAC. Licensed electricians and industrial controls technicians install this relay in motor control centers, HVAC control panels, and sequential process logic circuits where timed shutoff sequencing is required.

This relay is suited for light commercial and industrial control panel applications where delay-on-break timing is needed to manage load sequencing or fan overrun cycles. It carries a minimum delay of 1.2 seconds, making it appropriate for applications that require a brief controlled shutdown delay after a command signal drops. It is packaged as a single unit and is intended as a direct replacement or upgrade component in existing relay logic circuits.

Key Features

• Delay-on-break timer function holds contacts closed after control signal is removed
• Minimum delay of 1.2 seconds for timed shutdown sequencing
• DPDT contact configuration provides two independent switched circuit paths
• 10 amp contact rating supports light industrial and commercial control loads
• Dual voltage compatibility: 110 VDC and 120 VAC coil operation
• Single-unit packaging for direct replacement or panel retrofit use

Compatibility

Designed as an OEM-style replacement for DPDT time delay relay sockets and control panel assemblies requiring delay-on-break function with 10 amp contact ratings and 110 VDC or 120 VAC coil voltage.

Installation Notes

Installation should be performed by a licensed electrician following applicable NEC guidelines. De-energize and lock out the control panel before removing or inserting the relay. Verify that the existing relay socket and wiring are rated for the coil voltage being applied before powering the circuit. Do not exceed the 10 amp contact rating; overloading the contacts will cause premature failure or arcing damage.
