Definite Purpose Connectors
Definite Purpose Contactors
Definite purpose contactors are a device that is designed to handle high current circuits for specialized inductive and resistive loads. These loads include compressors, pumps, transformers and electric heating and lighting applications. Each Noark definite purpose contactor is designed to meet or exceed industry standards and handle a specific type of load to ensure that the equipment being controlled operates efficiently and safely.
