Full front accessibility for cable connections and current transformers (CT); this design feature ensures ease of maintenance, minimal usage of floor space and creates a safe environment.
Front & Rear Viewing Windows
Located on the front and rear of the assembly, these viewing casements allow complete access to viewing of the bus bar compartment for maintenance to assess any signs of overheating of the bus.
Infrared (IR) Viewing Ports (Optional)
Front and rear infrared viewing ports allow maintenance personnel to easily access thermal monitoring of the equipment without having to open the enclosure. IR technology ensures the operators safety while assessing the equipments internal components for possible overheating.
Insulated Bus Bar System
Medium Voltage insulating and support system with specialty designed structure for current transformers (CT’s). Epoxy insulated bus as standard.
KEMA-Powertest completed. Rigorous testing shows fully reinforced and sealed joints, hinges and latches, which reduce the risk of damage to maintenance personnel and other existing equipment in the event of an arc flash.
UL & cUL Listed, Meets or exceeds type 2A in accordance with ANSI/IEEE 37.20.7.
All enclosures are designed for specific application with improved dimensional flexibility and finished using state of the art powder coating system providing an indoor finish that exceeds the 1500 hour salt spray testing requirement for outdoor equipment to 3000 hours.
