The Circutor EC96 500V (code M10438) is a moving iron voltmeter for alternating current applications, measuring AC voltages up to 500 V without requiring an auxiliary power supply. It fits a standard 96 x 96 mm panel cutout and provides a 90-degree scale for immediate visual reading of voltage levels in AC installations.

• Certification: CE

Features and benefits:

• No auxiliary power supply required – the meter draws operating power directly from the measured circuit (1 to 4 VA), simplifying panel wiring.
• IP 52 front protection guards the instrument face against dust and light moisture in panel environments.
• Exchangeable scales compatible with EC48, EC72, EC96, and EM 45 series, reducing spare-parts inventory across multiple panel sizes.
• Wide frequency response from 20 to 100 Hz accommodates varied AC supply conditions.
• Class 1.5 accuracy (1.5% of full scale) delivers consistent readings suitable for panel-level voltage supervision.

Applications:

• Voltage monitoring on AC distribution boards and main switchgear panels in industrial premises.
• Control panel instrumentation where a compact 96 x 96 mm format and quick visual indication are required.
• Building and commercial electrical installations needing permanent panel-mount voltage display.
• Power distribution boards in light industrial and infrastructure environments operating at up to 500 V ac.
