CUBE SOLID STATE, 1 AMP

TH3AC Timers

TGC Delay on Make Relay Timer 10-30 Amps

Timing Mode | Anti-Short-Cycle

Category | Solid State Timer

Series | TH3AC

The TH3AC are Anti-Short-Cycle timers with solid state output for compressor protection.

An optional “Delay On Make” function is offered for sequencing or prevention of contactor chatter.

Simple 3 terminal connection and encapsulated 2" x 2" package.

Anti-short-cycle timers prevent premature cycling of compressors in refrigeration, air conditioning and heat pumps, there by reducing nuisance tripping of fuse or circuit breaker.

Timing Mode

When power is applied (i.e. thermostat closes), the load energizes. Removal of power begins the “lockout” and the time delay begins (i.e. locking out the compressor). The load is energized after the time delay expires.

Delay On Make option delays the initial load output for up to 5 minutes.
