Control relay for direct and indirect current monitoring, 1P+N, 1 changeover contact. Control and monitoring relay for undercurrent and overcurrent monitoring and current range monitoring (window function) in single-phase networks (L+N), with the option of storing the state (latch function - locking after tripping). Function, switching threshold values, hysteresis and tripping delay can be adjusted using 4 potentiometers. 4 control LEDs provide information on the state of the device. Current measurement can be carried out directly (up to 10 A AC) or indirectly via current transformers. Mounting on a top hat rail (DIN rail).
