This 5056100 ST-Blade Water Resistant Fuse Block from Blue Sea Systems provides IP66 protection for standard blade (ATO/ATC) fuses and standard blade-style low profile circuit breakers in a compact footprint.

Power to the block is supplied via a single cable (8.5-20mm²) and a busbar connects the 4 fused circuits that supply the loads (1.5-6mm² cable). Each circuit has a 25A current capacity with an 80A limit for the entire block.

Seals around the lid and cable entries ensure the block is protected against moisture ingress and the unit is supplied with 3 plugs to seal un-used cable entry points. Connection is via standard ring terminals with no special tools required and the fixings and other metal components are corrosion resistant for use in marine environments.

The tethered cover is secured using manual thumb-screws (no tools required) and features spare fuse and fastener storage inside. Write-on labels are provided for circuit identification.

This block can be nested with other ST-Blade Water Resistant Fuse Blocks and with Water-Resistant 100A Busbars to reduce cabling.
