Latching Relays

500 amp continuous
2500 amp cranking

This new range of High Power Latching relays are available in 3 formats for 3 different main functions. They include a waterproof remote control with 30 ft of pre wired loom. The Latching relays also have a built in emergency manual override facility in case of faults and also for safety when undergoing maintenance.

Latching relays versus conventional relays

A conventional relay requires power to hold the relay on line, however a latching relay only uses power to change the contractors position, then the relay latches into position and uses no more power to remain in that position, ideal for long term use where power is important.

Option 1: remote engine isolation switch

Features include:

1. Waterproof remote on/off.
2. Safety interlock to prevent unit being switch off with engine running.
3. High voltage trip, in event of alternator failure the unit will disengage the engine and so save your system auxiliary system
4. Internal emergency safety alternator circuit to protect the alternator in the event of the relay opening when the engine is running to protect the alternator
5. 5)2500 amp surge / cranking rating to deal with engine start

Option 2: voltage sensitive latching relay

Features includes

1. Water proof remote with automatic or manual select
2. Connection to up to 2 engines starter solenoids to disengage the relay during engine start to protect voltage sensitive equipment and voltage spikes
3. 20 second delay on latch on and 20 second delay on latch off
4. High voltage disengage (to protect battery bank)
5. Automatic voltage sensitive relay charging ability on automatic , on at 13.3 off at 13 with time delays ( x 2 for 24 v )
6. Over-ride ability via remote for starting assist, or manual override for emergency

Option 3: remote system feed latching relay

Features includes

1. Waterproof remote on off
2. High voltage 16 volts High voltage protection x 2 for 24 v of expensive secondary equipment in event of alternator failure
