Overview

The ABB ST201M-B15NA is a 1-pole + Neutral (1P+NA) Miniature Circuit Breaker (MCB) from ABB Electrification, designed for reliable circuit protection in single-phase applications. This device features a rated current of 15 Amperes (I_n = 15A) and a B-characteristic tripping curve, which is ideal for circuits with low inrush currents such as lighting circuits, control systems, and general-purpose distribution. The B-curve provides rapid response to overloads and short circuits, ensuring immediate protection against faults. With a breaking capacity of 10kA, the ST201M-B15NA effectively limits fault currents, enhancing safety for personnel and equipment by preventing damage from high fault currents. Its 1P+NA configuration ensures comprehensive protection for single-phase circuits, including the neutral line, making it suitable for applications where neutral protection is required. Engineered for DIN rail mounting, this MCB offers straightforward installation in electrical panels and distribution boards, simplifying integration into existing systems. Manufactured in Switzerland (CH), the ST201M-B15NA adheres to stringent industry standards, ensuring dependable operation and compatibility within various electrical systems. It is part of the ST201M series, known for its consistent performance and long-term reliability in commercial, industrial, and residential applications requiring precise circuit protection. The device is designed to meet IEC 60898-1 and other relevant standards, ensuring compliance with global electrical safety regulations. Its compact design and modular structure allow for easy integration into ABB’s S200 series distribution boards and other compatible systems. The ST201M-B15NA is also RoHS-compliant, reflecting ABB’s commitment to environmental sustainability. With a rated operational voltage of 230/400V AC and a rated frequency of 50/60Hz, it is optimized for use in both domestic and industrial environments. The breaker’s thermal-magnetic tripping mechanism ensures precise and reliable operation, while its high-quality materials contribute to its durability and long service life.
