Square D 9050JCK23V20 Dpdt Time Delay Relay

Product Description

The SQUARE D 9050JCK23V20 is a double-pole double-throw (DPDT) time delay relay designed for control circuit applications requiring a delay-on-break timing function. It operates on 110 volts DC or 120 volts AC and is rated for 10 amps of contact current. The minimum delay period is 0.6 seconds. This relay is used in HVAC, industrial control, and equipment sequencing panels where a timed break in the control circuit is required after the control signal is removed. Installation is typically performed by licensed electricians or HVAC controls technicians.

The 9050JCK23V20 fits applications where a delay-on-break function is needed to stage equipment shutdowns, prevent short-cycling, or manage sequencing in low-voltage and line-voltage control circuits. It is suited for both commercial and light industrial control panels. The delay-on-break configuration means the output contacts remain closed for the set delay period after the input signal is lost, then open at the end of the timed interval.

Key Features

• Delay-on-break timer function holds output contacts closed after input signal drops
• DPDT contact configuration provides two independently switched circuits
• 10-amp contact rating handles typical control circuit loads
• Dual voltage compatibility: 110 volts DC and 120 volts AC
• Minimum delay period of 0.6 seconds

Compatibility

Designed as an OEM-style replacement relay for control panels and equipment requiring a DPDT delay-on-break timing relay rated at 110 VDC or 120 VAC.

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. Verify that the supply voltage matches the relay coil rating before energizing. Reference NEC requirements for control circuit wiring and enclosure standards applicable to the installation location.
