AC Current Probe Model MN373 The Model MN373 is the latest in Features Applications compact AC current probes. It is Small, compact size Measur ing in breaker panels designed to meet the most stringent demands in industry and electrical Measurement range of Industrial loads contracting. Model MN373 meets 0.01 to 150A HVAC EN 61010, 600V, Cat. III safety Large jaw opening accommodates standards and is CE Marked and Residential and commercial sites conductors up to 250MCM UL approved for Canada and 5A secondary current tr ansformers United States. Designed for DMMs, loggers, (CTs) monitoring recorders and oscilloscopes The Model MN373 has a 0.78 (20mm) Data logging/recording jaw opening and accommodate 40Hz to 10kHz response conductors up to 250MCM. The 1000mV/A ca 10mV/Aca unique hooked jaw design facilitates output signals clamping and hooking onto Designed to EN 61010, 600V, conductors. Polycarbonate materials Cat. III safety standard and ultrasonic welding are used throughout to ensure ruggedness UL approved for Canada and and overall lasting reliability. United States The Model MN373 is a high Doub le Insulation performance model and uses a CE Mark custom nickel core to improve a ccuracy and phase shift on the low end of the measurement range. The Model MN373 is an excellent probe to be used in power and low level current measurement applications.
