Challenger CF3020 U is a three-pole molded-case circuit breaker rated for 20 A at up to 600 V AC, designed to protect three-phase circuits in electrical distribution panels and industrial equipment. This CF3020 U unit is part of Challenger's CF-type family and carries an interrupt rating of up to 25 kAIC at 480 V, enabling it to safely interrupt fault currents on typical commercial and light-industrial feeders. With its 3P configuration and 20 A rating, the CF3020 U provides reliable overcurrent protection for three-phase systems where compact MCCB protection is required; verify compatibility with your Challenger-compatible panel and trip characteristics before replacement.
