NARVA Heavy Duty Mini Battery Isolator Switch
Control your boat’s battery connection with NARVA part 700153, an on/off battery isolator for a compatible DC installation.
The on/off function provides a dedicated means of connecting or isolating the battery circuit. Choose the switch by the actual continuous load and any short-duration demand, using the separate ratings below.
This mini version uses a compact keyed knob that can be removed. Compare the body diameter and required mounting opening, as the mini-switch variants use different cut-out sizes and current ratings.
Continuous, intermittent and cranking figures describe different operating conditions. Keep any stated time limits and voltage conditions with their corresponding ratings when comparing switches; the highest number does not describe the allowable continuous load.
Choosing and using this product
For a panel-mounted item, check the cut-out and the clearance behind the panel as well as the visible dimensions. Terminals, cable bends and access for tools can require more room than the front of the component suggests. Confirm the mounting arrangement before altering the panel.
Check the exact supply format when ordering service parts. A replacement cover, boot, label, fuse or switch is distinct from a complete panel or assembly. Match the existing model and the stated part reference so that the item renews the intended component.
Keep circuit labels and the fitted product reference with the boat’s electrical records. This makes later fault-finding and replacement enquiries more straightforward. Before returning equipment to use, check the completed installation and its operation using the applicable instructions.
Plan the component together with the circuit wiring and protection. Follow the equipment instructions for the required connections and ratings, and keep the installation accessible for inspection. A component rating should not be treated as the rating of the entire assembled circuit.
