They are mechanical auxiliary parts without electrical switching function.
• Certification: No separate Ex certificate for these accessories. They are supporting parts for main explosion-proof operating units and shall be used together with certified main devices.
• Material: Protective covers and latches are mainly made of engineering plastic; name-plates are plastic or metal; spanner is metal.
• Exposed Fasteners: No independent exposed fasteners. Installed by clipping or sleeving onto push-button operating heads, no extra screws required.
• Electrical-Rated Voltage: None. Accessories are non-live, not part of electrical circuit.
• Electrical-Rated Current: None. Accessories are non-live, not part of electrical circuit.
• Protection-Ingress Protection: No individual IP rating. The protection performance is determined by the complete assembled push-button unit.
• Protection-Ambient Temperature: No separate parameter. Operating temperature follows the main explosion-proof push-button device.
• Connection-Cable Cross-section: None. These are external mechanical fittings, no cable involved.
• Connection-Cable Entry: None, no cable entry structure.
• Connection-Cable Gland: None, no cable gland required.
