Solenoid Coils
Class “ B” Coil (S6A)
The molded water resistant
Class “B” solenoid coil, available
on most Refrigerating Special-
ties solenoid valves, is designed
for long life and powerful
opening force. The standard coil
housing meets NEMA 3R and 4
requirements. This sealed
construction can withstand
direct contact with moisture and
ice. The coil housing far
exceeds the requirements of NEMA Standard ICS.1-110.57
salt spray test for rust resistance.
By definition, Class “B” coil construction will permit coil
temperatures, as measured by resistance method, as high
as 130°C (266° F). Final coil temperatures are a function of
both fluid and ambient temperatures. The higher fluid
temperatures require lower ambient temperatures so the
maximum coil temperature is not exceeded. Conversely,
low fluid temperatures permit higher ambient temperatures.
The supply circuits must be properly sized to give adequate
voltage at the coil even when other electrical equipment is
operating. The coil is designed to operate with line voltage
from 85% to 110% of rated coil voltage. Power consump-
tion during normal operation will be 33 watts or less.
Standard Encapsulated Coils
For other voltages, contact factory. On transformer coil, the 6 volt
leads are always black.
Class “ H” Coil (S6B)
The Refrigerating Specialties
Division molded water resistant
Class “H” coil is designed for
long life and powerful opening
force. The Class “H” coil
construction will permit coil
temperatures, as measured by
resistance method, as high as
180°C (365° F).
The supply circuits must be properly sized to give adequate
voltage at the coil leads even when other electrical equip-
ment is operating. The coil is designed to operate at 15%

Coils are available from stock with most standard voltages (see table below). Non-standard voltages
(shown in the shaded area of table) are available as special order. Coils are also available with 6V
secondary voltage for use with remote pilot lights PLT-1 and PLT-2. Consult factory for other voltages.
NOTE: Pilot lights cannot be used with explosion proof or unleaded coils.
