Industrial Circuit Breakers and Residual Current Devices from ABB
ABB offers a comprehensive range of industrial-grade protection devices, including residual current devices (RCDs), residual current circuit breakers with overcurrent protection (RCBOs), and miniature circuit breakers (MCBs). These devices are engineered to safeguard electrical installations against leakage currents, overloads, and short circuits. RCDs are designed to detect any imbalance between live and neutral conductors, tripping the circuit when leakage current flows to earth, thus preventing electric shock and fire hazards. They are typically used in series with an MCB or fuse to provide both overcurrent and earth fault protection. RCBOs combine both functions in a single compact unit, offering space-saving and reliable protection. ABB's MCBs feature a DIN rail mounting system, ensuring seamless integration into industrial control panels and distribution boards. They are available in various tripping characteristics (B, C, D) and breaking capacities to suit different application requirements.
Applications and Sectors
These devices are essential for industrial environments such as manufacturing plants, process industries, power generation facilities, and commercial buildings. They are installed in main distribution boards, sub-distribution panels, and motor control centers to protect circuits powering motors, conveyors, lighting, HVAC systems, and other critical equipment. Their robust design ensures reliable operation under harsh conditions, including high ambient temperatures, vibration, and electrical noise.
Subcategories and Key Articles
Key subcategories include:
- Residual Current Devices (RCDs): e.g., ABB F200 series (2P, 4P, 25A-63A, 30mA-300mA)
- Residual Current Circuit Breakers with Overcurrent Protection (RCBOs): e.g., ABB DS201 series (1P+N, 6A-40A, 30mA)
- Miniature Circuit Breakers (MCBs): e.g., ABB S200 series (1P, 2P, 3P, 4P, 0.5A-63A, 6kA-25kA breaking capacity)
The article codes typically follow a pattern like "2CDS2xxxxxxx" for S200 MCBs and "2CSF2xxxxxxx" for F200 RCDs.
