Phoenix Contact 3211903 PT 4-HESILED 24 (5X20) Fuse modular terminal block

The PT 4-HESILED 24 (5X20) from Phoenix Contact is a fuse modular terminal block providing single-position overcurrent protection using G / 5 x 20 glass or ceramic fuses, rated at 24 V nominal voltage and 6.3 A nominal current. An integrated LED optical signal unit gives instant visual fuse status indication, and the tool-free push-in connection method eliminates screwdriver wiring for fast panel assembly. Compatible with NS 35/7.5 and NS 35/15 DIN rail profiles, it is suited for machine building, plant engineering, and railway industry installations.
