These "CDS" series continuous duty relays are sold in non-grounded insulated cases (lightning proof). Available in either 12-15 volts and 24-30 volts. Use for building your own controller or upgrading your existing controller. Great addition to a dump load for diverting or controlling wind and or additional solar up to 10,000 watts on many pwm or mppt charge controllers.

Can be operated at 100% duty cycle conducting loads up to 440 amps or 10,000 watts. These are not like standard relays that can only run for short durations before burning up but are true industrial duty models that are not bothered by heat, dirt or continuous ON time!
Silver nickel alloy stationary contact, cadmium plated copper moving contact.
Heavy duty external LUGS complimented by .999 fine PURE silver alloy internal contacts that can handle millions of cycles at very high amp loads without fusing together and sticking!
