FAQs
What is the maximum continuous current the switch can handle?
The switch is rated for a maximum continuous current of 275A.
What is the purpose of the removable knob?
The removable knob provides a means to completely isolate the battery system for safety and security.
Is the switch suitable for use in an engine room?
Yes, it meets the ISO8846 Ignition Protection standard, making it suitable for engine room use.
What type of terminals does the switch use?
The switch uses tin-plated copper terminals for excellent conductivity and corrosion resistance.
What voltage systems is the switch compatible with?
The switch is compatible with battery systems up to 48V.
How do I mount the switch?
The switch can be surface or panel mounted. Mounting hardware is usually included or can be acquired separately.
What should I do if the switch gets wet?
The switch has some degree of weather resistance, but it is not fully waterproof. If the switch gets wet, ensure it is completely dried before operating. Check for corrosion and replace if needed.
Can I use this switch for both my house and starting batteries?
Yes, provided the total current draw of both systems does not exceed the switch's 275A rating. However, it's best to use separate switches for independent battery management, especially if you have two independent batteries.
Troubleshooting
Device not receiving power
Check the switch position (ON/OFF), and ensure the knob is properly inserted. Inspect connections for corrosion or loose wires.
Switch overheating
Check if the current exceeds the switch's rating. Check connections for any shorts or loose connections.
Difficulty turning the switch
Ensure the knob is properly aligned and inserted. Inspect the switch mechanism for any obstructions.
Battery draining despite switch being OFF
Check for parasitic loads in your system. Inspect the switch for any internal failures (replace if needed).
