Challenger CH3090 is a molded case circuit breaker designed for providing reliable overcurrent and short-circuit protection in three-phase electrical systems. It features a 90A current rating and a 480V AC voltage rating, with a robust thermal-magnetic trip unit offering both long-time and instantaneous (LI) protection functions. The breaker is constructed as a three-pole, bolt-on unit with a compact design, weighing 1 lb, and is rated for operation in temperatures from -25°C to 70°C (-13°F to 158°F). It complies with the UL 489 standard for molded-case circuit breakers and carries an interrupting capacity of 10kA at 240V. This breaker is typically applied in industrial panelboards and switchboards, accommodating copper or aluminum conductors from #10 to 1/0 AWG.
