ATFL4220BK

The ATFL4220BK from Amphenol PCD represents the pinnacle of Terminal Blocks - Din Rail, Channel technology for data center power distribution. The high-density design and superior thermal management make it ideal for server farm and network equipment applications.With Disconnect, Feed Through isolation architecture, this terminal block minimizes crosstalk in high-current busway systems. The proprietary dielectric material maintains stable properties up to 105 C ambient.The Fuse, Lever safety mechanism allows hot-swapping of PDU connections. The positive-lock indicator provides tactile confirmation of secure connections.The 2 position configuration supports N+1 redundant power schemes. Each contact features silver-tin plating that resists fretting corrosion in vibration-prone environments.Engineered with 1 isolated levels, this solution separates primary and backup power feeds. The vertical stacking design reduces cabinet space requirements by 40%.Precision-machined 8.0mm terminals ensure reliable connections under continuous load. The tapered contact design maintains constant pressure during thermal cycling.The Screw interface combines tool-less installation with industrial-grade retention force. Field testing demonstrates 10,000 mating cycles without contact degradation.Rated for 6.3 A continuous current, the terminal meets TIA-942 requirements for data center applications. The thermal design handles inrush currents up to 400% of rating.With 500V dielectric strength, the insulation system withstands transient surges common in UPS systems. The proprietary polymer formulation maintains properties from -40 C to 125 C.UL-recognized for 6.3 A operation, the component exceeds NFPA 75 requirements. The flame-retardant material prevents fire propagation in rack installations.Listed for 220V per UL 489, the terminal block is certified for branch circuit protection. The arc-resistant design contains internal faults without external flashover.Compatible with 10-22 AWG data center cables, the terminals feature integrated strain relief. The dual-crimp design prevents strand migration in fine-wire conductors.Integrated LED enable real-time temperature monitoring. These predictive maintenance capabilities interface with DCIM systems via Modbus TCP/IP.The Black housing meets data center color-coding standards for phase identification. The high-contrast design remains identifiable in low-light server aisle conditions.Designed for 5mm x 20mm, 5mm x 25mm data center protection devices, the fuse carrier meets UL 248 standards. The quick-change design minimizes downtime during maintenance windows.
