Why Choose the TE Connectivity D1.5/8.SFLT.ADO 1SNA199211R2300 Fuse Terminal Block?
The TE Connectivity D1.5/8.SFLT.ADO 1SNA199211R2300 is a compact ADO fuse terminal block with blown-fuse indication and test sockets from the Entrelec SNA ADO range. Designed for circuit protection in industrial control applications, it accepts 5 × 20 mm and 5 × 25 mm cartridge fuses and provides a convenient means of isolating and protecting individual circuits within DIN rail terminal assemblies.
This version incorporates a 110–230 V blown-fuse indicator, allowing maintenance personnel to identify a failed fuse quickly, together with two integrated test sockets for convenient circuit testing. The ADO insulation displacement connection system is designed for fast, reliable conductor termination and is particularly suited to control applications exposed to vibration, shock and other demanding industrial conditions.
With an 8 mm width, grey thermoplastic housing and conductor capacity of 0.34–1.5 mm², the 1SNA199211R2300 provides a space-efficient fused connection for control panels and automation equipment. The terminal is rated at 6.3 A and 500 V and is designed for mounting on standard 35 mm DIN rail.
