Effective January 2013
Overview
Introduction
Order instruction
Standard conformance
W-SLC is a contactor fuse combination withdrawable truck for use in indoor switchgear. It is rated at a continuous current rating of 400A
(with conductors) and 200A (with 355A fuses) and used up to 7.2kV 50Hz AC power systems. Incorporating Eaton’s fixed type SL series
of medium voltage vacuum contactors
.
W-SLC adds medium voltage current limiting fuses for short-circuit protection, to control medium
voltage equipment such as 3-phase motors, transformers, capacitor banks and is especially used in applications where frequent
operations are required.
