Heavy-Duty 300 Amp Isolator Switch for Reliable Power Management

Secure Electrical Isolation for Marine, RV, and Off-Grid Systems

Managing high-current power networks requires robust hardware to ensure safety and consistent performance. Designed for professional and DIY installers, the Exotronic 300A Red On Off Battery Switch provides reliable electrical isolation for demanding applications. Capable of handling up to 300A continuous current and a 900A peak rating for 30 seconds, it is built to manage heavy loads effortlessly. With a maximum operating voltage of 48V, it is fully compatible with 12V, 24V, and 48V setups, making it highly versatile for a lithium battery switch upgrade, solar battery switch installation, or a comprehensive dual-battery system.

Whether you are outfitting an off-grid caravan, a commercial work vehicle, or a complex marine vessel, having a dependable cutoff point is critical. It allows you to safely disconnect power during maintenance, prevent parasitic battery drain during storage, and quickly shut down systems in emergency situations. By integrating high-quality materials and strict engineering standards, the Exotronic 300A Red On Off Battery Switch mitigates the risks of voltage drop and overheating often associated with lesser alternatives.

Engineered for Harsh Australian Conditions

Mobile and off-grid environments expose electrical components to extreme vibration, dust, and moisture. To combat these elements, this marine on off switch features an IP66 international protection rating, ensuring excellent resistance against heavy water spray and dust ingress. The fully enclosed rear housing includes convenient breakout panels, enabling flexible and secure cable routing while maintaining structural integrity.

For marine applications, ignition protection is a critical safety factor. This marine on off battery switch is ignition protected, making it safe for installation inside engine compartments where flammable vapours may be present. This significantly reduces the risk of accidental ignition, providing peace of mind for inboard petrol and diesel engine setups.

Optimised Connectivity and Ease of Use

Proper electrical connections are essential for minimising resistance in high-amperage circuits. This battery isolator switch features heavy-duty 3/8" (Approx. M10) terminal studs, designed to accept large heavy-duty lugs and heavy-gauge cables. The robust terminals ensure a secure, high-surface-area contact point for efficient power transfer. Additionally, the ergonomic rotary actuator provides a clear, high-contrast visual indication of the on-off position, ensuring the system status is immediately recognisable at a glance.

The high-visibility red housing ensures rapid identification in emergency situations, making it ideal for primary master isolation.

Key Features

  • High Current Capacity: 300A continuous and 900A peak (30s) rating for heavy-duty applications.
  • Broad Voltage Compatibility: Rated up to 48V DC, suitable for 12V, 24V, and 48V electrical systems.
  • Weatherproof Construction: IP66 rating protects against dust and high-pressure water spray.
  • Ignition Protected: Safe for installation in marine engine rooms and enclosed compartments.
  • Robust Terminals: 3/8" (Approx. M10) threaded studs ensure secure, low-resistance connections.
  • Flexible Installation: Removable rear breakout panels allow for tidy, multi-directional cable entry.

Upgrade Your Power Control

Ensure the safety and longevity of your electrical system with a reliable, heavy-duty isolation solution. Equip your vessel, caravan, or solar installation with the Exotronic 300A Red On Off Battery Switch and experience professional-grade power management today.

Great watch - Nice large display!!
After my old Timex Ironman finally died after 21 years of reliable service (may it rest in peace after 4 replacement bands and 5 replacement batteries!!), I decided Timex deserved another sale from me! So I went surfing on the Timex website. So many Timex Ironman watches to choose from! But this one stood out for two reasons. 1) It has a nice simple design without a lot of "noise". 2) A nice large readable display. So I took the plunge! Indeed, Timex has definitely improved on their Ironman watches in the last 21 years. Most notably, the Indiglo light has greatly improved. It used to just light up the background. Now, it brightly lights up the actual digits which makes it undeniably readable without any eye strain. Another great improvement are in the set features. While the older models could only be set forward (in other words, if you went past your set point, you would need to go all the way around), this model lets you set forward and backward (so if you go too far, you can step back without going around). I don't understand one of the reviewers saying that the watch is too small. The face is quite large. The band may seem narrow in proportion to the watch face, but not excessively so. The band is 19mm wide and fits me just fine. Highly recommended!!

Like it so far after 2 weeks of swimming.
Like it so far after 2 weeks of swimming. Have been careful nio to press buttons underwater. I Like the large numerals, backlight, countdown timer, stopwatch and alarm. My last Timex 1440 lasted 10 years before the battery was low enough that the backlight was too weak to see at night. I replaced the battery on it but did not seal the o ring well enough with silicon grease so it leaked and quit working. I also had also replaced the band once.

Little Small On The Wrist
Really cool timepiece, been loving timex a lot recently, this is me coming over Casio/G-shocks. Although it is a bit smaller on the wrist it still looks very nice and I really love the gray and like green color contrast. Really easy to read the time as well.

Sturdy and digital
This watch has “ fake screws” holding the band on . The band is actually held on by the usual pins holding it on most watches but weaker . The pin came off while I was putting it on for the first time! This is the second time I bought off Amazon in 2 weeks where the watch appeared to be sturdy and the pins fell off . Going back to military watches that have material straps that go completely around wrist and do not have pressure on pins
