UL 489/UL 1077 DIN Rail Miniature Circuit Breakers

Eaton Electronics UL 489/UL 1077 DIN Rail Miniature Circuit Breakers are designed for branch service applications. These devices are available with B, C, and D characteristics with UL^® 489, CSA^® C22.2 No.5, UL 1077, CSA C22.2 No.235, and IEC 60947-2. The circuit breakers include standard ratings of 10kAIC up to 277/480V_AC, contact position indicator (red/green), and 17.7mm width of module (per pole). These devices are suitable for branch circuit device protection and thermal-magnetic overcurrent protection and are current-limiting. The circuit breakers are available in two terminal configurations: standard box terminals with multiple conductors and ring-tongue terminals.
