PROTECTIVE ARRANGEMENT, MOTOR VEHICLE AND METHOD FOR OPERATING A PROTECTIVE ARRANGEMENT FOR PROTECTING A HIGH-VOLTAGE BATTERY OF A MOTOR VEHICLE

A protective arrangement for a motor vehicle for protecting a high-voltage battery of the motor vehicle from the penetration of liquid. The protective arrangement has an electrical component connected to the high-voltage battery via a cable, which component has a drainage device with a drain opening and a closure, by which the drain opening can be released depending on the pressure, a cooling circuit with a circuit component arranged on the component housing, through which component a coolant can flow, and with a pump to pump coolant through the circuit component, and a control device, which is designed to control the pump depending on detection of at least a probable penetration of coolant into the component housing in such a way that an increased pump power is at least temporarily provided by the same if the pump is not yet in a state of maximum pump performance.
