Simpson Electric Co. 55F1600 Analog Panel Meter

The Simpson Electric Co. 55F1600 Analog Panel Meter is a round, 3.5-inch dial analog panel meter from Simpson’s 55-series lineup, engineered for panel-mounted indication of electrical signals within industrial control panels, test benches, and equipment racks. It uses an iron vane movement and is transformer-rated for reliable readings in energized circuits, with many 55-series units specified for a 5 A transformer rating, ensuring compatibility with common control-transformer configurations. The 55 family includes ranges such as 0–100 A AC on the round 3.5-inch dial and features a black knife-edge pointer that provides precise, easily readable scale markings. To fit standard instrument openings, these meters typically require a 3.5-inch panel cutout in ANSI C39.1 style, and Simpson supplies support through distributors for the appropriate mounting hardware and electrical connections. Made in the USA, these meters reflect Simpson’s longstanding manufacturing heritage and are a durable, factory-supported option for panel instrumentation.
