WFCO 8700-AD Power Centre Diagrams: 8725, 8735 & 8740

WFCO's 8700-AD power centres bring together a 12V converter/charger, AC breakers and a DC fuse board. Use this guide to identify a WF-8725-AD, WF-8735-AD or WF-8740-AD, compare the fuse arrangements and find the matching model in our catalog.

Where the main components sit

Viewed with the front door open, the 35A and 40A models place the AC breaker compartment on the left, the converter cooling area near the middle and the DC fuse board on the right.

Model differences and fuse ratings

The output ratings, available fuse circuits and reverse-battery protection vary by model. The fuse arrangement is therefore not interchangeable just because the cabinet looks similar.

Model Output current DC fuse circuits Reverse-polarity fuses AC breaker capacity
WF-8725-AD 25A Four: three branch and one battery One 30A 30A main, up to three branch circuits
WF-8735-AD 35A Six: five branch and one battery One 40A 30A main, up to five branch circuits
WF-8740-AD 40A Six: five branch and one battery Two 30A 30A main, up to five branch circuits

On the 8735-AD and 8740-AD, the manufacturer identifies six DC fuse circuits and permits higher-current positions within the stated limitations. Standard branch fuses are ATO/ATC type; choose the rating specified for the individual protected circuit, not just the maximum the panel can accept.

Indicators, battery charging and service

The DC board uses red indicators to flag blown fuses. A repeat failure after replacement requires the circuit to be checked. The Auto-Detect charging system selects the applicable charging profile for lead-acid/AGM or lithium batteries. Check the model label inside the door instead of assuming every WFCO 8700 unit has Auto-Detect.

Find the complete WFCO power centre

Each card links to the exact numbered model and its product photos, details and current availability. These are complete units rather than individual fuse-board replacements.

Earlier 25A model for comparison

The WF-8725-P is a different, earlier model. Its presence here helps identify a similar-looking unit, not establish direct replacement compatibility.
