0100055000 Battery Disconnect Relay
HOW IT WORKS:
RELAY OPENING
Negative polarity applied to coil. Current flowing in coil. Plunger pulled in. Rod magnet opposite the plunger. Swings out to side of housing
RELAY OPENING
Power removed. No current flowing in coil. Plunger pushed up by return spring while magnet is off to theside. Contacts open. Rest at side of plunge
RELAY CLOSING
Positive polarity applied to coil.Current flowing in coil. Plunger pulled in to coil. Rod magnet attracted to plunger by opposite polarity.
RELAY CLOSING
Power removed from coil.Magnet blocks plunger from coming up, maintaining contact.

I was hoping this was a motorized latch, but it is an electromagnet based latch. On the bright side, it connects faster than a motor switch would, but, it takes 10x more current to do so. I'm using mine in a solar application. I'll stick with it, but it's quite loud and strong when it triggers. Enjoy.

The Drkerr Battery Disconnect Relay is built old school Tough! I must say that this isn't the quietest Relay that I have used, it makes a distinct clack when engaged leaving no doubt in your mind that it has engaged. That being said this is a Heavy Duty Relay designed to Work, and boy does it work! I have been using this Relay Solenoid for several months now with no issues whatsoever. For my hard earned money I want Old School Tough & Reliable! I am Five Star Happy with the Performance of the Rock Solid Drkerr Battery Disconnect Relay.

Husband installed today and our 2004 diesel van started right up. Original lasted 20 years!

I won't go into a long review explaining what this replay is supposed to do, as in what a latching relay generally is, and how an automotive battery disconnect works, as the product page provides plenty of good detail, specs and target application explanations.I a few words however, this is a heavy-duty battery disconnect relay capable of passing 100A continuous or 500A Short-Time Load, and its coil only needs about 3 Amps for a very short time to turn it on or off (to close or respectively open its contacts) after which the relay coil does not require any power at all and this way saving your battery from having an unnecessary load for extended periods (especially useful during an RV storage situation or a battery backup application).One thing to mention here is that the relay coil (I and S) connections will require the control voltage to reverse polarity in order to switch the relay from on to off, so if this product doesn't go to replace a compatible relay into an existing system, the coil control power will need to wired into a double-pull double throw (DPDT or 2P2T) switch circuit in order to reverse current polarity to the coil, and the switch is also best to be of the momentary type, to only send power to the coil for a brief time before coming to a neutral position that disconnects the coil form power.Another thing to mention is the fact that this is a 12-volt solenoid type latch relay (an electromagnet-based device), which although very loud, it switches current very fast, which is much better than a motorized latch relay which are quieter but also slower and less reliable due to potential arc developing when contacts are opening under load, which is fairly common in high current applications for this type of product.Lastly, this relay is relatively easy to install and seems to work flawlessly, and it is also a good value for the price offered. Now we'll have to see in time if it holds up to its specs and for how long.
