The SIEMENS 3RU21160FB0 thermal overload relay is designed for current-dependent protection of loads with normal starting against excessive temperature rises due to overload or phase failure. It protects connected loads from overheating and causing damage. An overload or phase failure results in an increase of the motor current beyond the set rated motor current.
Trip Type Class 10
