50 WAGO-1881 4-conductor 4-pin Fuse Terminal Block Gray 10A 300V 5.2mm

Description:

The Wago 1881 4-Conductor 4-Pin Fuse Terminal Block is a DIN rail-mounted electrical protection and distribution component designed to provide fused circuit protection, wire termination, and signal distribution within industrial control panels and automation systems. Commonly installed in PLC cabinets, machine control panels, process automation equipment, manufacturing systems, and industrial electrical enclosures requiring protected field wiring connections. Maintenance electricians, panel builders, OEM manufacturers, and system integrators use this terminal block for control panel assembly, circuit protection upgrades, electrical maintenance, and replacement of damaged fuse terminal assemblies.

Applications:

The Wago 1881 Fuse Terminal Block is commonly used in industrial automation systems, control cabinets, machine wiring installations, process control equipment, building automation systems, and power distribution panels where conductors require both secure termination and overcurrent protection. Its fused design helps protect sensors, control circuits, field devices, and low-current electrical loads while simplifying troubleshooting and maintenance within commercial and industrial electrical systems.
