Magnetic Calibrator for Residual Current Circuit Breaker consists of pneumatic cylinders and microprocessor controls to give accuracy and absolute stability. The Magnetic Calibrator generates unidirectional pulses for magnetic saturation and damped oscillatory pulses for the calibration of the magnet assembly. The Magnetic Calibrator is offered in automatic or semiautomatic manner. The Magnetic Calibrator for Residual Current Circuit Breaker comes with a printer for recording the batch to batch and the total days production.
