Single-pole 24 V DC fuse block

This single-pole fuse block accepts midget-class fuses up to 30 A at 24 V DC. The finger-safe polyamide body mounts on DIN rail and uses a pressure-plate connector for 14 to 6 AWG wire. It suits installers who need a compact, touch-protected overcurrent point in low-voltage DC panels.

Indicating non-rejection design

The block includes a visual indication feature and a non-rejection fuse fit, so any compatible midget-series fuse from the listed range seats without a keyed rejection feature. This simplifies stocking because one block covers many fuse part numbers such as A60Q, AGU, ATM, ATQ, BAF and others.

30 A headroom on DIN rail

At 30 A the block reaches its rated limit, so circuits that may exceed this current need a higher-rated device. The 0.69 in width allows dense rail packing, while the 2.32 in height and 3.07 in length fit standard enclosures. Buyers who need multi-pole ganged protection or AC voltage ratings must select a different block.

Questions about this item

How often will the fuse inside this block need replacement under normal load?

The block accepts UL Class Midget fuses rated 0 to 30 A; replacement depends on the fuse you select and the circuit conditions, not on the block itself.

What limits continuous current before the block overheats?

The pressure-plate terminals accept 14 to 6 AWG wire and the polyamide body is rated for the full 30 A range at 24 V DC.

Does the block generate noticeable heat or noise when powered all day?

As a passive fuse holder it produces no audible noise; any warmth comes from the installed fuse carrying its rated current.
