Circutor M10426 EC72 300V Voltmeter

The Circutor EC72 300V (code M10426) is a panel-mount moving iron voltmeter for alternating current circuits. It measures AC voltage up to 300 V with class 1.5 accuracy and fits a standard 72 x 72 mm panel cutout, operating directly from the measured circuit without any separate auxiliary power supply.

Features and benefits:

• No auxiliary power supply required - the instrument draws its operating power from the measured voltage circuit, reducing panel wiring complexity.
• True RMS measurement provides accurate voltage readings across a broad range of AC waveforms.
• Scales are interchangeable with EC48, EC72, EC96 and EM 45 series instruments, giving flexibility when reconfiguring panels.
• IP 52 rated front face protects the dial against dust ingress and water splashes in typical industrial enclosures.
• Frequency response from 20 to 100 Hz covers standard grid frequencies as well as variable-speed and generator applications.

Applications:

• Continuous AC voltage monitoring on industrial switchboards and motor control centres.
• Voltage indication in power distribution cabinets where a compact 72 x 72 mm panel instrument is specified.
• Visual voltage checks in commercial building electrical installations and main distribution boards.
• Generator set and UPS output panels requiring direct, self-powered voltage indication.
