The T.R.A.P.™-B is a device for your car that contains a 5,000-watt transient voltage suppression device in a form factor that can be easily connected across a vehicle’s battery terminals. Putting this on your battery will help protect your vehicle from load changes (such as your A/C kicking on and off), conducted transients from a charging port, radiated energy from a nearby lightning strike or an overhead electromagnetic pulse (EMP).
The T.R.A.P.-B comes in a weatherproof package with ring terminals for easy install and attachment. The weatherproof module is IP68 rated with integrated rubber o-rings, automotive-grade wire, copper terminals, and marine-grade heatshrink. It contains the same AEC Q101 qualified transient suppression device as the T.R.A.P.™ but in a more convenient form factor for use across the battery.
How can the T.R.A.P.™ be effective against an EMP when it’s so small?
The danger to vehicles from an EMP is the high voltage that is introduced on the cables from E1 and E2. Those transient voltages are extremely brief in time (from nanoseconds to microseconds) and can therefore be suppressed using small devices. This is distinctly different than the case with homes, which would also experience a powerful E1 current surge from the power grid.
Is it ok to use multiple T.R.A.P.s in one vehicle?
Yes, putting energy “traps” at multiple points in your vehicle does a better job shunting away the unwanted energy. Maximum protection is achieved by using a T.R.A.P.™ in every auxiliary power outlet, as well as using the T.R.A.P.™-B across the vehicle’s battery.
Does a T.R.A.P.™ protect a vehicle even when the vehicle is powered off?
The T.R.A.P.™ provides transient protection even with the ignition switch turned off because interconnected cable assemblies can still receive damaging energy. The T.R.A.P.™ continues to act as a high-frequency energy sink even when the vehicle is unpowered.
Will a T.R.A.P.™ or T.R.A.P.™-B drain my battery?
T.R.A.P.™ products draw essentially zero current except when there is a significant overvoltage, so they won’t drain your battery.
How do I change out the ring terminals on the T.R.A.P.-B?
