Product Overview
KYN28-24 armored removable AC metal-enclosed switchgear is used to receive and distribute electrical energy and to control, protect, and monitor circuits in three-phase AC. It is commonly used for medium-voltage power distribution systems and distribution rooms requiring removable switchgear, with the final selection based on rated data, drawings, and site conditions.
EPC companies, electrical contractors, utility project teams, panel builders, and industrial buyers can request configuration review for medium voltage switchgear. Please send single-line diagram, rated voltage, rated current, short-circuit level, protection scheme, busbar arrangement, and cabinet layout, quantity, destination, and any project standard requirements for quotation.
