The SENTRON 8WH2 spring-loaded fuse terminal for 6.3×32 mm (1/4″×1-1/4″) G-type cartridge fuses. Rated 10A/400V — a distinct step above the 6.3A/250V variants (1JGxx). The larger fuse body dissipates more heat, enabling the higher current rating. The 110–250V AC/DC LED indicator connects directly to mains-voltage control circuits — no step-down transformer or separate DC supply needed for fault monitoring.

How is the 10A fuse terminal different from the 6.3A variants?

Three differences: (1) Current rating — 10A vs 6.3A, suitable for control transformer secondaries and higher-power instrument loops. (2) Fuse format — 6.3×32 mm (1/4″×1-1/4″) vs 5×20 mm, a physically larger cartridge with greater rupture capacity. (3) Physical size — 8.15mm wide and 76.5mm tall, versus 6.15mm wide and 61.5mm tall for the 6.3A variants. The 10A terminal occupies roughly 32% more DIN rail width.

Can I use this terminal on a 24V DC control circuit?

The fused main circuit — yes. The 10A/400V rating covers 24V DC loads. But the LED indicator requires 110–250V AC/DC to illuminate. On a 24V panel, the LED will not work. If you need low-voltage LED monitoring with 10A fuse protection, consider using an external monitoring solution or selecting a lower-voltage LED variant from the 6.3A range.

What is the difference between 1RG08 and 1MG08?

Both are 6.3×32 mm G-fuse terminals. The 1RG08 is rated 10A/400V with 110–250V LED. The 1MG08 is rated 6.3A/250V — same fuse format but lower current and voltage limits. Choose based on your maximum load current and required LED indicator voltage.
