Replacing a battery disconnect or choosing a switch for an RV electrical system? BEP's 700, 701, 701S and 720 may look related, but they do not all switch the same way. The 701S selects between two batteries; the other three models provide ON/OFF isolation. Compare the actual contact functions, ratings, mounting sizes and product photographs before ordering.
What each switch does: functional contact diagrams
700, 701 and 720: single-circuit master disconnect
ON
Internal contact closed: the switch's two main studs are connected.
OFF
Internal contact open: the main current path is interrupted.
Conceptual contact states only. The terminal positions, required circuit protection and cable arrangement must follow the exact BEP installation documentation.
701S: four-position, two-battery selector
The selector has three main studs rather than the two on a standard ON/OFF model. These are the switch's electrical contact states:
BOTH connects the two battery banks; this selector does not isolate sensitive electronics from engine-starting voltage spikes. This is a function guide, not a wiring instruction.
BEP switch specifications by exact part number
Manufacturer-rated values below are for the specific BEP models named, not all similar-looking switches. All four have a 48V DC voltage rating.
| Part | Switch positions | Continuous | 5-min intermittent | 10-sec cranking | Main studs | Approx. L × W × H |
|---|---|---|---|---|---|---|
| BEP 700 | Easyfit ON/OFF | 275A | 455A | 1250A | 2 × 3/8 in | 68 × 68 × 110 mm |
| BEP 701 | Contour ON/OFF | 275A | 455A | 1250A | 2 × 3/8 in | 69 × 69 × 75 mm |
| BEP 701S | 1 / 2 / BOTH / OFF | 200A | 300A | 1000A | 3 × 5/16 in | 69 × 69 × 75 mm |
| BEP 720 | Heavy-duty ON/OFF | 600A | 800A | 2500A | 2 × 1/2 in | 102 × 102 × 90 mm |
The 700 Easyfit style is designed for recessed mounting through panels, while the 701 uses BEP's Contour locking format. The 701S is a compact selector in the same general footprint as the 701. The larger 720 is a heavy-duty ON/OFF switch; it is not a four-position selector.
