RESET TIMERS

Three-Phase Monitor Relays continuously monitor and detect voltage faults to protect equipment in three-phase systems. These relays retain indication and continue monitoring even with a lost phase. True RMS voltage measurement ensures more accurate sensing across more applications.

Accurate Timing For Critical Applications

An onboard potentiometer makes setting the time delay easy. Termination is convenient with 0.25 inch quick connect terminals. Select from eleven time ranges. An LED indicates timing and relay status.

Surface Mounting

The compact 2” x 2” enclosure installs with a single bolt or screw through the center mounting hole. Models are available with or without memory of timing sequence.

Frequently Asked Questions About Reset Timers

Macromatic RT series Reset Timers are electronic and microprocessor based. This design approach offers highly reliable, repeatable and accurate timing cycles. The RT series is available with or without memory. For applications that require memory, the standard RT Series retains timing cycle status when power is lost. When power is restored the timer continues timing without resetting the timing cycle. For applications that do not require memory, Macromatic offers the product without memory as well. The non-memory version resets the timing cycle to zero when power is removed. When power is reapplied, the timing cycle always starts at the beginning.
