You can connect more than one piece of equipment to a variable stage or relay as long as they are the same type (for
example, two fans), and the total current draw (load) is within the limits.

The FLA (full load ampere) rating accounts for the increase in motor current draw when the motor operates at less
than full speed. Make sure the motor/equipment connected to the variable stage does not draw more than the FLA rating.

Actuators require two relays: one for opening, one for closing. You can connect a maximum of two actuators.
Tip : You can increase the load capabilities of the Supra´s variable stages 3 and 4 by connecting slave units. Each slave
unit increases the current capacity of the stage it is connected to by 20 A. For more information, read Slave units on
page 11.
Using power contactors to increase the capacity of relays
Phason’s 240-volt power contactors are heavy-duty relays that allow you to increase the load
handling capability of control relays. Power contactors are ideal for secondary ventilation fans and
electric heaters.
Phason’s power contactor relays have the following electrical ratings.

Coil: 10.2 mA at 240 VAC

Contact: 25 A at 240 VAC; resistive
2 HP at 240 VAC, 1 HP at 120 VAC; motor, power factor 0.4
1300 W at 120 VAC; tungsten
Phason offers three power contactor options.

Power contactor relay
(model PC-240) – includes power contactor relay and mounting hardware
for easy mounting in an enclosure.

Power contactor kit
(model 122-1) – includes power contactor relay, on-off-auto switch and
label, snubber filter (reduces electrical noise), and mounting hardware for easy mounting in an
enclosure.

Power contactor unit
(model 129-0) – includes two power contactor relays, two on-off-auto
switches, and two snubber filters, mounted in a large enclosure. The enclosure has room for two
additional contactor relays or kits.
