Square D 9050JCK22V20 Dpdt Time Delay Relay 10A

Product Description

The SQUARE D 9050JCK22V20 is a double-pole double-throw (DPDT) time delay relay rated for 10 amps contact current and dual voltage operation at 110 volts DC and 120 volts AC. It is configured for a Delay On Break timer function, meaning the output contacts remain energized for a set period after the control signal is removed before switching to the de-energized state. Minimum delay starts at 0.3 seconds. This relay is installed in industrial control panels, HVAC sequencing circuits, and commercial electrical systems where a controlled off-delay is required to protect motors, compressors, or other loads from abrupt shutdowns.

The 9050JCK22V20 is suited for applications requiring timed switching in low-voltage and line-voltage control circuits. Common install scenarios include motor control centers, HVAC fan delay circuits, and general-purpose relay logic panels in both commercial and light industrial settings. The Delay On Break configuration is particularly useful for fan post-purge sequences, blower coast-down timing, and similar applications where load shutdown must be staged.

Key Features

• DPDT contact configuration provides two independent switched circuits in a single relay body
• Delay On Break timer function holds contacts closed after signal removal for controlled sequencing
• 0.3 second minimum delay time supports fast-cycle timing applications
• Dual-rated coil operates at 110 volts DC and 120 volts AC
• 10 amp contact rating handles standard control circuit loads
• Compact form factor at 4.6 inches length, 2.3 inches width, and 1.9 inches height

Compatibility

Designed as an OEM-style replacement for DPDT time delay relay applications in industrial control panels and HVAC sequencing circuits requiring 120 VAC or 110 VDC coil voltage with Delay On Break functionality.

Installation Notes

Installation should be performed by a licensed electrician familiar with control circuit wiring and applicable NEC requirements. De-energize and lockout the panel before removing or installing any relay. Verify coil voltage matches the control circuit supply before energizing. Confirm contact load does not exceed the 10 amp rating for the connected circuit.
