ABB offers an extensive portfolio of miniature circuit breakers (MCBs) and residual current devices (RCDs), engineered for both commercial and industrial environments. The MCBs are designed to protect electrical installations against overloads and short circuits, ensuring operational safety and reliability. These modular switches, featuring DIN rail mounting, comply with all standard requirements for circuit breakers, making them suitable for integration into domestic, commercial, and industrial applications. For smaller installations, models like the S200 series provide a breaking capacity up to 10kA. ABB also provides a range of differential switches (RCCBs) that focus solely on protecting against earth leakage currents without overcurrent protection; these are typically used in series with an MCB or fuse to handle thermal and dynamic stresses. Combined residual current circuit breakers with overcurrent protection (RCBOs) integrate both functions into a single device, disconnecting the circuit in the event of earth leakage, short circuits, or overloads, up to their specified maximum short-circuit current.
These devices are primarily installed in distribution boards, control panels, and automation systems within tertiary and industrial sectors. Common applications include commercial buildings, factories, data centers, and infrastructure projects where reliable circuit protection is critical. They are also used in renewable energy systems, such as solar photovoltaic installations, and in heavy machinery requiring robust electrical safety.
Key subcategories include the S200 series MCBs (e.g., S201, S202, S203, S204 with 1P, 2P, 3P, 4P configurations), F200 series RCCBs (e.g., F202, F204), and DS200 series RCBOs. The product codes typically follow a pattern: for MCBs, 'S2' indicates the series, followed by poles (e.g., '01' for 1P) and current rating (e.g., 'B16' for 16A curve B). For RCCBs, 'F2' denotes the series, with poles and sensitivity (e.g., 'F204-40/0.03' for 4P, 40A, 30mA). These devices are available in various breaking capacities (up to 10kA or 25kA) and trip characteristics (B, C, D curves).
