Compatibility / Fitment Guide
| Check | Required specification | Decision |
|---|---|---|
| Variant | 4374 for four circuits; 4376 for six | Choose by required circuit count and available panel height. |
| System | 12V or 24V DC | All loads, backlighting and downstream wiring must match system voltage. |
| Branch load | ≤15A at 12V or ≤9A at 24V and protected by the supplied 15A breaker | If a load needs a smaller breaker, replace/specify protection appropriate to the conductor and device. |
| Total load | ≤45A cumulative across the panel | Do not multiply the branch rating and ignore the panel limit. |
| Mounting | Correct cut-out, gasket/sealing and protected rear terminals | IP67 depends on installation; allow 88.9mm depth plus cable bend radius. |
Not suitable for: AC mains distribution, more than 45A cumulative load, circuits whose conductor/device requires protection below 15A without a breaker change, or unprotected rear-terminal exposure.

Frequently Asked Questions
Do both variants include breakers?
Yes. These are the 4374/4376 circuit-breaker panels, not the switch-only 4305/4307 models.
Can every circuit draw 15A simultaneously?
No. The stated cumulative panel rating is 45A.
Which panel is 152.4mm high?
The six-position 4376. The four-position 4374 is 109.22mm high.
Does IP67 cover exposed rear wiring?
Do not assume so. Correct front mounting and protected rear wiring are still required.
Before ordering: Select 4374 or 4376, then confirm circuit count, system voltage, individual/total current, cut-out and rear clearance.
