The KILLARK XCS-0S3C5 is a selector switch designed for use in hazardous location electrical installations. Selector switches of this type allow operators to choose between two or more operating positions in a control circuit, making them a standard component in industrial control panels and equipment. This unit is built to KILLARK's specifications for environments where standard electrical devices are not rated for use, such as areas with flammable gases, vapors, or combustible dusts. Licensed electricians and industrial maintenance technicians are the primary installers of this type of equipment.
The XCS-0S3C5 is suited for industrial and commercial applications where hazardous location-rated control devices are required. Typical installations include petrochemical facilities, refineries, grain handling operations, paint booths, and other classified areas as defined under the National Electrical Code. This selector switch provides reliable operator control in environments where ignition risks demand explosion-proof or hazardous-rated enclosures and components.
Designed as an OEM-style replacement or direct-install hazardous location selector switch for industrial control panel applications where KILLARK or equivalent rated devices are specified.
Installation must be performed by a licensed electrician familiar with NEC Article 500 requirements governing hazardous classified locations. De-energize and lockout/tagout all affected circuits before beginning installation or removal. Verify that the enclosure and all associated wiring methods meet the Division or Zone classification of the installation area. Do not install this device in an energized panel or in a location that exceeds its hazardous location rating.
