Simpson Electric M235-0-0-46-0 Ac Ammeter Panel Meter

Product Description

The SIMPSON ELECTRIC M235-0-0-46-0 is a 3-1/2 digit digital LCD panel meter configured as an AC ammeter for electrical panel and control cabinet applications. It accepts input up to 5 amps and 250 VAC across a frequency range of 4 to 440 Hz, making it suitable for both standard 50 Hz and 60 Hz power systems as well as variable-frequency drive applications. The display uses red LCD digits for high-contrast readability in control panel environments. Screw terminals provide a secure, field-wireable connection. Licensed electricians and industrial maintenance technicians are the primary installers of this type of instrument.

This panel meter is used to monitor AC current in residential, commercial, and light industrial electrical panels, motor control centers, generator switchgear, and custom control enclosures. Its wide frequency tolerance of 4 to 440 Hz makes it a practical choice for installations involving variable-frequency drives or non-standard power sources. The compact panel-mount form factor is designed to drop into a standard cutout and secure from the front.
