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 Black 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 Black 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 battery 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 discreet black faceplate seamlessly integrates into modern control panels and dashboard setups for a clean, professional finish.

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.

Great price great shoe
Size: 12, Color: Burgundy Polished Full Grain
Excellent shoe. Tried the Sebago penny loafer and the sizing was ridiculous. These J and M are sized perfectly. I’ve had them before and they wear like iron. Very comfortable right out of the box.

Poor quality control - maybe outlet store leftovers
Size: 11.5, Color: Burgundy Polished Full Grain
The two shoes were not the same size. They were both labeled 11 1/2 but one shoe was larger than the other and the fit was poor. I returned the first pair and ordered a replacement. This time the shoes were close to the same size but too loose and the left one has sewing issues. I've bought Johnston & Murphy for years because of the quality. These were to replace an existing pair of burgundy penny loafers that have finally worn out (even after several heal/sole replacements). That is the expected quality. I suspect Nashville Shoe Warehouse may be handling shoes that didn't measure up for the quality; more like an outlet mall than getting the J&M quality I've come to expect. Update: went to Johnston & Murphy site to buy "direct" from the manufacturer. There were several recent reviews where the shoes were long and didn't fit properly. Genesco - please step up the manufacture / crafting of these classic shoes to the level of quality they used to have.
