ORMULA is the fruit of ABB's decades of experience and effort. FORMULA is designed for simplicity and practicality, suitable for a wide range of applications, particularly meeting customers' requirements for space volume and ease of installation.
The FORMULA series consists of three frames: A1, A2, and A3, with frame currents of 125A, 250A, and 630A, respectively. All frames are fixed and come with standard front terminal connections. The pre-set thermal magnetic release units are straightforward and easy to select, ensuring on-site installation without errors, convenient for equipment manufacturers' workers and future component replacements by customers. The compact size, easy ordering, simple installation, and quick setup provide users with unprecedented simplicity.
FORMULA integrates all the characteristics of ABB's high quality, high reliability, and simplicity, making it a truly practical molded case circuit breaker. The size has been reduced, yet it still ensures excellent performance and reliability, and has more than
All similar circuit breaker products on the market have a high performance-to-size ratio, providing users with more space for cable routing and reducing the size of switch cabinets. The compact size offers significant advantages, particularly for OEM manufacturers, PCB manufacturers, and...
Installers find this especially suitable. FORMULA A1 and A2 are high-performance circuit breakers capable of handling 250A current at a depth of 60mm.
The FORMULA series molded case circuit breakers feature the following characteristics:
Double Insulation
• Reliable operation
Isolation Function
Electromagnetic Compatibility
• Power can be fed from above or below
• Multi-directional installation allows for horizontal, vertical, or side-laying placement of circuit breakers without affecting performance.
• Below 2,000m in altitude, no derating is required. Above 2,000m, due to changes in atmospheric conditions (air composition, dielectric strength, cooling capacity, and atmospheric pressure), there is an impact on the main parameters of the circuit breaker.
