Simpson Electric 10340 Analog Ac Voltmeter 300 Vac

Product Description

The SIMPSON ELECTRIC 10340 is an analog AC voltmeter panel meter designed for monitoring alternating current voltage in electrical panels and control systems. Rated for a maximum input voltage of 300 VAC at 60 Hz with an impedance of 50,000 ohms at 60 Hz, this meter provides reliable analog readout for trade applications. It uses a screw terminal connection and is recognized under UL File E91015, making it suitable for use in listed electrical enclosures and panel assemblies. Licensed electricians and control panel builders are the primary installers of this type of instrumentation.

This panel meter is intended for use in AC electrical monitoring applications where a direct-reading analog display is preferred over digital instrumentation. It is specified for use with the 1359 0-300 VAC 4-1/2 model panel meter configuration, making it a direct fit replacement or original-install component in compatible panel assemblies. Typical installation environments include industrial control panels, electrical distribution boards, and HVAC equipment control enclosures where continuous voltage monitoring is required.

Key Features

• Analog display for direct, real-time AC voltage readout without power supply dependency
• 300 VAC maximum input voltage rating suitable for standard single-phase monitoring
• 50,000 ohm impedance at 60 Hz minimizes loading effect on monitored circuits
• Screw terminal connections for secure, tool-based field wiring
• UL Recognized under File E91015 for use in listed panel assemblies
• 60 Hz operating frequency matches standard North American AC power systems

Compatibility

Specified for use with the 1359 0-300 VAC 4-1/2 model panel meter assembly. Designed as an OEM-style panel meter component for AC voltage monitoring applications in compatible electrical enclosures and control panels.

Installation Notes

Installation should be performed by a licensed electrician in accordance with the National Electrical Code (NEC). De-energize and lock out the panel or circuit before wiring the meter terminals. Screw terminal connections should be tightened with an appropriate screwdriver to ensure a secure, low-resistance contact. Verify that the source voltage does not exceed the 300 VAC maximum input rating before energizing the circuit.
