Battery switches may look similar from the front yet control different electrical paths. Blue Sea's m-Series 6006, 6007 and 6008 are single-circuit or battery-selection switches. The larger e-Series 5510e and 5511e operate two separate circuits, but only the 5511e includes a manual COMBINE BATTERIES position.

Each photograph links to its own NewRVParts listing. A pictured electrical component is not included with a different product unless specifically listed in that product package.
6006 — m-Series Single-Circuit ON/OFF Battery Switch2 positions; one battery input; 300A continuous
6007 — m-Series 4-Position Battery Selector SwitchOFF, battery 1, battery 2 and BOTH selection
6008 — m-Series 3-Position Battery Selector SwitchOFF, battery 1 and battery 2; no combine position
5510e — e-Series Dual-Circuit Battery SwitchOFF/ON for two isolated circuits, without battery combine
5511e — e-Series Dual Circuit Plus Battery SwitchOFF/ON/COMBINE; 350A continuous rating per circuit
Identify the correct model
| Manufacturer part | Switch type | Control positions | Combine banks? |
|---|---|---|---|
| 6006 | m-Series single circuit | OFF / ON | No |
| 6007 | m-Series battery selector | OFF / 1 / 2 / 1+2 | Yes |
| 6008 | m-Series battery selector | OFF / 1 / 2 | No |
| 5510e | e-Series dual circuit | OFF / ON | No; two circuits remain isolated |
| 5511e | e-Series Dual Circuit Plus | OFF / ON / COMBINE BATTERIES | Yes, for emergency combination |
Electrical ratings and key installation differences
The manufacturer ratings and functions below apply to the specified models. Compare the exact product instructions and installed circuit before purchasing.
| Switch group | Manufacturer rating | Identification point |
|---|---|---|
| 6006 m-Series | 300A continuous; maximum 48V DC | Single battery input; one switched positive output |
| 6007/6008 m-Series | 300A continuous; maximum 32V DC | Two battery inputs, one selected load path; 6007 alone has the combine position |
| 5510e e-Series | 350A continuous per circuit; maximum 32V DC | Simultaneously opens or closes two isolated circuits |
| 5511e e-Series | 350A continuous per circuit; maximum 32V DC | Two isolated ON circuits with an additional combine function |
| m-Series studs | 3/8-inch terminals; 120 in-lb terminal torque | Verify cable termination clearance and Blue Sea mounting drawing |
| e-Series studs | 3/8-16 (M10) terminals; 140 in-lb terminal torque | Surface or rear-panel mount, following the product-specific manual |
| Separate charging relay | 7622 ML-ACR automatic charging relay | Automatic battery combining and isolation is not the same function as a manual battery switch |
