Integrated RA series

Transfer Switch

The integrated version of the RA series

includes 20 spaces for breakers and a

transfer switch in one enclosure. These

products are Listed to UL 67 and CSA

C22.2 No.29, and are UL1008 compliant.

The switch assembly and generator set

combination are specifically designed for a

simplified, quicker installation.

This UL/CSA switch is suitable for standby

power systems in residential and light

commercial applications. This product

adheres to National Electrical Code (NEC)

and National Fire Protection Association

(NFPA) requirements.

This switch monitors utility power 24 hours a

day and 7 days a week. When utility power

becomes unsatisfactory or fails; the

generator set is signaled to start, then

automatically transfers the load. When

stable utility voltage returns, the transfer

switch will automatically switch electrical

load from the generator to the utility. No

action is required by the home owner.

RA112L1 | 2 Transfer switch mechanism A powerful and economical solenoid powers RA Transfer Switches. Independent break-before-make action is common for 2-pole. Mechanical interlock prevents simultaneous closing of normal and emergency contacts. Electrical interlocks prevent simultaneous closing signals to normal and emergency contacts and interconnection of normal and emergency sources through the control wiring. Long-life, high pressure, silver alloy contacts resist burning and pitting.
