Put your circuit breakers to the test with this RCD tester from Megger. It assesses various electrical properties of your safety devices, including voltage and current, so you can ensure they're in top form to reduce the risk of hazards. To check trip currents, it raises current levels in 10% increments to the point where the unit is set off. The LCD screen holds the recorded value for easy logging. This tester's rubber case is resistant to wear and impact, so it's fit for use in rugged work locations.
