Service Breakers
Circuit breakers are devices designed to open or interrupt an electrical circuit when the current exceeds a preset value or a short circuit occurs, preventing damage to machinery and installations. Unlike fuses, they do not require replacement after each operation; simply reset the alarm via the switch. ABB offers a comprehensive range of service breakers, including open frame and molded case circuit breakers, covering all protection needs with features like adjustable trip settings, high breaking capacities, and various pole configurations (3P, 4P).
These breakers are essential in industrial and commercial electrical panels, distribution boards, and automation systems. They are used in sectors such as manufacturing, energy, infrastructure, and building management, providing reliable overcurrent and short-circuit protection for motors, transformers, and other critical equipment.
Key subcategories include molded case circuit breakers (MCCBs) like the ABB SACE Tmax series (e.g., T1, T2, T3, T4, T5, T6) and open frame breakers (ACBs) such as the ABB SACE Emax series (e.g., E1, E2, E3, E4, E6). Article codes typically follow a pattern like '1SDA...' for MCCBs and '1SDA...' for ACBs, indicating specific ratings and accessories.
We offer express worldwide shipping and specialized engineering support for product selection, configuration, and troubleshooting, ensuring optimal protection for your electrical systems.
