The SENTRON 8WH2 spring-loaded fuse terminal accepts standard G-type cartridge fuses in 5×20, 5×25, or 5×30 mm formats. When the fuse element opens, the front-facing LED illuminates — giving maintenance personnel an instant visual fault indication without a multimeter or removing the fuse. The spring balancer connection accepts 0.08–4.0 mm² solid or stranded conductors without ferrules, up to 4.0 mm² with ferrules. No end cover plate required.

How do I choose between the 30–60V, 15–30V, and 110–250V LED variants?

Match the LED indicator supply voltage to your control circuit. The 30–60V range (1JG68) covers 24V and 48V DC circuits. The 15–30V variant (1JG38) suits 12V and 24V DC circuits. The 110–250V variant (1RG08) is for mains-voltage AC/DC panels. The LED monitoring circuit is independent of the fused main circuit — its voltage requirement is solely for the indicator, not the protected load.

What is the difference between G-fuse and blade-fuse SENTRON 8WH2 terminals?

G-fuse terminals (this product family) accept cylindrical glass cartridge fuses — the standard format for electronic and instrumentation circuits. Blade-fuse terminals (8WH2000-1BGxx) accept automotive-style ATO/ATC blade fuses and are rated for higher currents (30A). G-fuse variants are narrower (6.15mm) and target lower-current circuits where precise fuse characteristics and fast replacement are priorities.

How many terminals fit on a standard DIN rail?

At 6.15mm wide, approximately 162 of these terminals fit per metre of 35mm DIN rail. The compact width makes it practical to fuse-protect individual signal lines in dense control panels without consuming excessive rail space.
