Simpson Electric 35075 Analog Ac Ammeter Panel Meter

Product Description

The SIMPSON ELECTRIC 35075 is an analog AC ammeter panel meter designed for measuring alternating current in electrical panel and switchboard applications. Rated for a maximum input of 50 amps AC, it operates at 60 Hz with an internal resistance of 0.008 ohms. The meter uses a moving-pointer analog display, giving technicians a direct, real-time current reading without requiring digital power or backlighting. Screw terminals provide a secure, low-resistance connection point. Installation is handled by licensed electricians working on panel-level instrumentation or industrial control enclosures where permanent current monitoring is required.

This panel meter is suited for residential, commercial, and light industrial electrical installations where AC current measurement at 60 Hz is needed. It mounts directly into a panel cutout and is intended for use with the 1357 0-50/0-5 AAC 3-1/2 model panel meter system, making it a direct match for that instrument configuration. Electricians use this type of meter in motor control centers, distribution panels, and switchboards to provide continuous amperage indication at the panel face.

Compatibility

Specified for use with the 1357 0-50/0-5 AAC 3-1/2 model panel meter. Designed as a panel-mount AC ammeter for 60 Hz electrical systems requiring analog current indication up to 50 amps.

Installation Notes

Installation should be performed by a licensed electrician in accordance with applicable NEC requirements. De-energize the circuit and verify zero voltage before making any terminal connections. Screw terminals must be tightened securely to prevent arcing or high-resistance connections. Confirm the panel cutout dimensions match the meter housing before mounting.
