Simpson Electric 10220 Analog Ac Voltmeter Panel Meter

Product Description

The SIMPSON ELECTRIC 10220 is an analog AC voltmeter panel meter designed for fixed-panel electrical monitoring applications. Rated for a maximum input voltage of 150 VAC at 60 Hz with an impedance of 25,000 ohms at 60 Hz, it provides reliable voltage indication on AC electrical systems. The meter uses screw terminals for secure, low-resistance connections and features an analog display for continuous, real-time voltage readout. Electricians and instrumentation technicians install this type of meter in control panels, distribution boards, and equipment enclosures where live voltage monitoring is required.

This panel meter is suited for residential and light commercial electrical panels, industrial control cabinets, and custom-built electrical enclosures requiring analog voltage display. It is designed for 60 Hz AC systems operating within the 0-150 VAC measurement range. The analog format makes it a practical choice in environments where a quick visual check of voltage level is preferred over a digital readout. Installation is typically performed by licensed electricians during panel construction or retrofit service work.

Key Features

• Analog display for continuous, real-time AC voltage monitoring
• Maximum input voltage of 150 VAC at 60 Hz
• Impedance of 25,000 ohms at 60 Hz for minimal circuit loading
• Screw terminal connections for secure, tool-tightened wiring
• UL Recognized under File E91015 for panel installation compliance
• Panel-mount format for integration into control boards and enclosures

Compatibility

Designed for use with the 1357 0-150 VAC 3-1/2 Model Panel Meter configuration as specified by the manufacturer.

Installation Notes

Installation should be performed by a licensed electrician in accordance with applicable NEC requirements. De-energize the panel and verify absence of voltage with a properly rated tester before wiring the meter terminals. Screw terminals require a flathead or appropriately sized screwdriver for secure conductor termination. Follow the panel meter manufacturer documentation for correct terminal polarity and conductor sizing.
