Overview

The ABB ST201M-C2NA Miniature Circuit Breaker (MCB) is a compact, high-reliability protective device designed for single-phase circuits requiring both phase and neutral disconnection. Part of ABB’s ST201M series, this MCB delivers precise overload and short-circuit protection with a 10kA breaking capacity, ensuring safe operation in industrial and commercial electrical systems. The C-characteristic tripping curve (Type C) makes it ideal for applications with moderate inrush currents, such as lighting circuits, small motors, and control panels, where nuisance tripping must be minimized while maintaining robust fault protection. Key specifications include a 2A current rating, 10kA breaking capacity, and a 1Pole+Neutral (1P+NA) configuration. The 1P+NA design simplifies wiring and installation in distribution boards, reducing panel space requirements while ensuring compliance with electrical safety standards. With a compact form factor and reliable performance, the ST201M-C2NA is optimized for use in control panels, lighting systems, and small motor applications where space efficiency and precise protection are critical. ABB’s ST201M series MCBs are built to meet the demands of modern electrical distribution systems, offering consistent performance across a range of operating conditions. The ST201M-C2NA is manufactured in Switzerland, reflecting ABB’s commitment to quality and engineering excellence. Its Type C tripping characteristic ensures rapid response to overloads while avoiding false trips in circuits with moderate transient surges, making it a dependable choice for applications where both safety and uptime are priorities. The ST201M-C2NA is part of ABB’s ST201M series, which includes models with varying current ratings and pole configurations, such as the A2A125TL-2 (2-pole, 10kA, 125A), A1A020TW-2 (A-characteristic, 10kA, 20A), and A2A200TT (3-pole, 10kA, 200A). This series is designed for applications requiring reliable protection in industrial and commercial settings, with breaking capacities ranging from 10kA to 25kA depending on the model.
