Phoenix Contact part number 899000 is a terminal block accessory, specifically a marking sleeve or label component. It belongs to the UCT series of marking materials designed for use with Phoenix Contact terminal blocks. The component is manufactured from polycarbonate and features a white color. It is intended for identification purposes within electrical control cabinets and industrial wiring setups. This item serves as a consumable accessory rather than an active electrical connection device.
Verify compatibility with specific terminal block models before purchase. Confirm that the marking sleeve dimensions match the target terminal block width. Ensure the material specification meets environmental requirements for the installation site. Check for any regional availability restrictions or supply chain limitations affecting this specific accessory part number.
Select this component when a standardized labeling solution is required for Phoenix Contact terminal blocks. Consider the polycarbonate construction for resistance to common industrial chemicals and abrasion. Evaluate the white color option against available alternatives if specific color coding is mandated by project standards. Ensure the accessory fits the mechanical constraints of the chosen terminal block series.
This part is an accessory within the broader Phoenix Contact terminal block ecosystem. It supports the organization and maintenance of complex wiring systems by providing clear identification points. The component complements the primary electrical connectors by adding necessary documentation and traceability features essential for compliant industrial installations.
