FAQs
Installation requires accommodating a bottom-feed, three-pole, three-wire fusible switch with a control power transformer. Plan for a 16 in Ă— 28 in Ă— 24 in footprint and a 175 lb unit weight, allowing room for mounting hardware, wiring terminals, and CTs. Use appropriate lifting equipment and secure mounting provisions to prevent movement during fault conditions.
The SCB2533B120480KE7 is rated for 2500A amperage with a 480V main voltage and a 120V control voltage. It operates in a three-pole, three-wire, fusible configuration with bottom feed. The UL Listed designation confirms compliance with safety standards for heavy-duty protection devices.
Yes. It includes an Arc Energy Reduction Relay and matched current transformers, and it ships with a control power transformer for 120V control circuits. This enables straightforward integration with common protection relays and plant control logic in MCCs, switchgear, and large feeders.
The SCB2533B120480KE7 is UL Listed, which provides evidence of safety and compliance with recognized standards. For procurement and QA processes, UL Listed components minimize risk and simplify supplier qualification, especially in regulated industrial environments.
Arc Energy Reduction Relay reduces fault-energy exposure, contributing to safer operations and potentially lower downstream damage during faults. Matched CTs improve protection accuracy and coordination, while the robust fusible construction supports longer service life in demanding environments, reducing maintenance frequency and unplanned downtime.
