1.1 Equipment
Unpacking the Equipment 1.
Before beginning installation, check the overall condition of the equipment. Remove packing materials, and examine all
components for signs of shipping damage. Any shipping damage is the customer’s responsibility and should be reported
immediately to your freight carrier.
The Circuit Breaker Switch provides overload protection and a disconnect for single phase fan motors and other electri-
cal equipment. Maximum voltage is 250VAC. An on/off indicating light and front seal are included. The Circuit Breaker
Switch cannot be held “ON” against an overload.
See ‘Selection Chart’ in Chapter 4 for matching Circuit Breaker Switch model to load.
Note:
Three phase motors require motor starters with three phase overload
protection. Contact your local electrician or electrical supply store.
