Are NEMA Type 12/3R safety switches provided with a hub opening in the top end wall?

Issue:
Product Features

Product Line:
Heavy Duty Safety Switch

Environment:
Applies to all NEMA 12/3R Heavy Duty Safety Switches

Cause:
Hub Selection

Resolution:
A hub opening is provided in the top end wall in NEMA 3R devices with an "RB" suffix. For all NEMA 3R devices with an "R" suffix instead of "RB", then a blank top end wall is provided.
If conduit entry is required through the top end wall of the "R" suffix devices, a field cut hole is required. Watertight ``H type`` hubs should be ordered separately.
