Cutler-Hammer D87AE On Delay Timer (Series A1) is an electrical timing relay with a 0.3–30 second on-delay range, designed for 120V, 50–60 Hz operation. When energized, the timer delays the activation of the output for the selected interval, enabling timed sequencing in AC control circuits. The D87AE designation identifies this specific timer in Cutler-Hammer's timing relay lineup, suitable for applications requiring a defined delay on power-up or control signal within 120V AC systems.
