STOP SWITCH & BATTERY ISOLATOR

Stop Switch, DC & AC Isolators

For use with all turbine models, these switches allow the user to isolate the DC supply to a load, to apply an electrical "brake" to the turbine and to isolate the AC side of an inverter (if connected). The AC isolator is a 4-pole 20A lockable switch, which should be used when connecting Grid-Tied Inverters to a "mains" supply. The switch should be mounted close to the main consumer unit, between a spare 16A breaker and the inverters.

The DC Isolator and Brake should be connected to the output of the wind turbine, between it and the load (inverter, batteries etc). The main rotary switch is rated at 63A and is 4-pole. In this mode, the internal connections have been pre-wired in pairs of 2 poles, giving a massive switching capacity of 120A. Also mounted inside these switches are a low resistance "dump load", allowing the turbine to slowed to a safe level before applying a direct "short circuit" to the turbine output wires.
