Item #291B293A33, Weschler Motor Load Analog Panel Meters

Weschler Conventional Types 351 and 371 and 20/20 Types G-332, G-352 and G-372 meet all performance requirements of ANSI C39.1-1981 for round and rectangular panel instruments. They employ conventional Taut Band mechanisms enclosed in black fluted cases or clear Lexan plastic windows designed to match the appearance of Westinghouse switchboard instruments and other devices used on traditionally styled control panels.

Features
