These resistors are natural air cooled and have a high ingress protection degree (IP65 / IP66). They are used in harsh environmental brake applications like cranes in harbors or on deck winches. Optional they are fitted with moisture and thermal overload protection and protection grid.
These resistors are used as brake resistor where the braking time is relative long and cycle time short. They are used in cranes and other lifting applications. For harsh environmental conditions we recommend GxxRT types.
