The SSAC (Littelfuse) THD3C43A1 is a dedicated repeat cycle solid-state timer from the THD Series, designed for applications requiring consistent, repetitive ON/OFF cycling of loads, such as motors, heaters, or lamps. It is encapsulated to protect against harsh environments and operates on 120VAC.
Key Features and Specifications:
Function: Dedicated Repeat Cycle (Recycle) - Starts with T1 (ON time) upon input voltage application.
Time Delay Range: 1 – 100 seconds (adjustable).
Input Voltage: 120VAC.
Output Type: Solid-state (no moving parts, providing long life).
Output Rating: 20A steady state; 200A inrush.
Adjustment: Single onboard variable resistor (knob) controls both ON and OFF times equally.
Repeat Accuracy: $\pm$0.5% or 20 ms, whichever is greater.
Termination: 0.25 in. (6.35 mm) male quick-connect terminals.
Mounting: Surface mount with a single #10 (M5 x 0.8) screw.
