UL 698A - UL STANDARD FOR SAFETY INDUSTRIAL CONTROL PANELS RELATING TO HAZARDOUS (CLASSIFIED) LOCATIONS - THIRD EDITION; REPRINT WITH REVISIONS THROUGH AND INCLUDING DECEMBER 14, 2016 Organization: UL
Date: 2012-09-14
Description: The industrial control panels covered by these requirements are assemblies consisting of components such as motor controllers, overload relays, fused disconnect switches, and/or circuit breakers and related control devices such as pushbutton stations, selector switches, pilot lights, timers, switches, control relays and the like with associated wiring terminals. In all cases, the enclosure is provided as part of the assembly.
