Metrohm E3640 4kV AC Flash Tester

The Metrohm E3640 is an AC flash tester for leakage and breakdown testing. It is designed for voltage testing of electrical apparatus, components and insulating materials. The E3640 is housed in a rugged, moulded plastic case with integral carrying handle. The hinged detachable lid is fitted with a pouch which contains all accessories and the instruction manual. All operating functions are mounted on a panel underneath the protective lid. The twin 3 1/2 digit LCD displays show both output voltage and leakage current. FEATURES 115V and 230V operation. 50/60Hz frequency selection. Applies up to 4kV AC. Displays output voltage and leakage current. Twin 3.5 digit LCD screens. Breakdown mode when fast transients can trigger tripping. Burn mode where the trip function is bypassed and the fault current flows continuously to expose the faulty. Hold function shows full breakdown of voltage and leakage current. Mains powered. Metrohm E3640 Specifications Electrical Power Requirement 115/230 V +15% 50/60 Hz 40 VA.
