We’ve often been asked if circuit breakers can be used as system disconnects in police cars and other vehicles with a large number of electrical accessories. Although using a circuit breaker this way may seem practical or cost-effective, it’s important to be aware of certain risks since most circuit breakers have not been designed for routine On/Off use.

How to Increase Battery Life with Battery Disconnects
Posted by R. Iversrud on Mar 28, 2022 8:11:39 AM
As commercial vehicles evolve, so does the need for increased protection of their electrical systems.
Modern vehicles have more auxiliary units drawing battery power than ever before. In the past, when vehicles were powered off, so were all electrical loads. Now, many of today’s commercial trucks require electricity full time.
Battery management is critical because increased loads, when not managed properly, can draw down batteries, leading to stalls and breakdowns.

Battery Isolators and Automatic Charging Relays (ACRs): A Comparison
Posted by R. Iversrud on May 12, 2021 8:39:52 AM
When it comes to battery management, battery isolators and automatic charging relays (also called ACRs or voltage sensitive relays) are both used to safeguard reserve battery power to prevent breakdowns and protect other vital vehicle or boat functions.
So, how are these two components different? Is one better than the other? When should you choose one over the other? Here are some things to keep in mind.
