Nordyne 276868 621678R 2 STAGE 3POLE SEQUENCER

2 STAGE 3POLE SEQUENCER

The 621678R 2 Stage 3-Pole Sequencer is a two stage, three pole, sequencer that will automatically shut off power to any single branch or phase of a 3-phase commercial air conditioning system for maintenance purposes. The unit has two independent circuit breakers and the front panel is illuminated with amber colored pilot lights. This device may be used with 2-3 poleyelectric operated contacts with the following ratings: 115V .. 15 amps; 208/230V ..

The Nordyne 621678R 2 Stage 3-Pole Sequencer features voltage sensing for precise operation and control. This Bad Ass breaker can be used with single pole supplies up to 600 amps; ideal for continuous duty applications. The voltage sensing feature is great for gauging the amount of current draw in a circuit as well as making sure that the wires can handle the amperage of the motor they are powering.

This 2 stage 3 pole sequencer provides both time delay and time reduction for any water to air or gas fired combination heating system. The sequencer allows a wide range of operating options like zero-degree, 10 second or delayed start and up to 15 minutes or more of operation. Standard 105C rating for control components and C.I. cast zinc frame provide added safety, while an easily accessible enclosure with LED indicating operation modes, is easy to maintain and service.

The Nordyne 276868 621678R 2-Stage 3-Pole Sequencer delivers more comfort, efficiency and safety than 2-stage systems that cost much more. It is designed to operate up to three low voltage air conditioning and/or heating appliances at the same time. Heating, cooling and ventilation systems have evolved from simple single-stage and two-stage controls many years ago into sophisticated, multi-stage electronic controls. They are now the high performance standard for HVAC

This is a Nordyne Control Board 2 Stage 3 Pole Sequencer. This comes with a new terminal strip, new terminal junction box, and new 2-3 Pole 20 amp 480 volt contactor . (Fits 2012 to Present)

The 2 stage, 3 phase Sequencer is a versatile time-saver that’s perfect for the construction or industrial site. The large LCD screen makes it easy to program for any combination of devices and events (e.g., pool pump, blower or HVAC) as well as schedule them to run in sequence or individually. Features: This unit can operate up to 24 different wired appliances from 1 board daily • Selectable 1 second, 10 second intervals for each device • Times

The Nordyne 2-stage Three-phase Sequencer single stage form a three phase to seven forms sequenced at speeds up to 210/230V A.C. (24 V D.C. Max) All stages are inhibitable for total control of motor start/stop.
