YX0501-ZK Changeover Switch & Operating Head

Technical Data

1.Explosion-proof Type

• Standards Implemented: YX0501-ZK change-over switch operating head is an internal electrical component without separate Ex certificate and must be fitted inside an enclosure complying with GB3836 for explosive atmospheres.
• Applicable Hazardous Areas: This switch cannot be used bare in explosive hazardous areas and can only work in relevant zones when assembled within a certified explosion-proof enclosure.
• Ex Marking: Gas protection: The switch itself has no independent Ex rating, and the final explosion-proof grade depends on its matched explosion-proof enclosure.

2.Product Parameters

• Product Type: Change-over switch operating head, multi-position rotary electrical component for circuit gear, start-stop and forward-reverse signal switching.
• Certification: No separate Ex certification shown on datasheet. It is built-in component and shall be used with certified explosion-proof enclosure.
• Material: Handle made of engineering plastic; base of insulating plastic; internal metal contacts.
• Exposed Fasteners: No exposed fasteners, fixed by panel cut-out clip-in mounting.
• Electrical-Rated Voltage: Max. 400V.
• Electrical-Rated Current: Max. 20A.
• Protection-Ingress Protection: No independent IP rating for component, protection performance depends on complete assembled enclosure.
• Protection-Ambient Temperature: No separate data on datasheet, operating condition follows matched explosion-proof enclosure.
• Connection-Cable Cross-section: Suitable for 2.5mm² conductor.
• Connection-Cable Entry: No cable entry on component itself. Cables connect to switch terminals; cable entry is provided by outer enclosure.
• Connection-Cable Gland: No gland supplied. Cable glands are installed on outer explosion-proof enclosure.
