GHB3020 - 20 Amp Circuit Breaker Description
GHB3020 - 20 Amp Circuit Breaker
The Eaton GHB3020 is a 20 Amp, 3-pole molded case breaker built for commercial and industrial electrical systems. Part of Eaton's Series C G-Frame line, it uses a T186 thermal-magnetic trip unit to protect your circuits from overloads and short circuits. Rated for 480Y/277V AC and 125/250V DC, it fits distribution panels, motor control centers, and switchgear assemblies where space is limited and reliable protection is required. Its compact G-Frame design helps ensure a clean, efficient installation, and the high interrupting ratings—14 kAIC at 480Y/277V AC and 65 kAIC at 240V AC—handle fault currents safely in demanding environments.
