Overview

The ABB ST201M-Z10NA Miniature Circuit Breaker (SKU: ST201M-Z10NA) is a precision-engineered protective device designed for sensitive electronic and lighting circuits. Manufactured by ABB Electrification, this breaker is part of the ST201M series, optimized for applications requiring rapid tripping under fault conditions while minimizing nuisance tripping from transient surges. The Z-characteristic tripping curve ensures immediate response to overcurrents, making it ideal for protecting circuits with low inrush currents such as electronic equipment, control systems, and LED lighting installations. With a rated current of 10 Amperes and a breaking capacity of 10 kA, the ST201M-Z10NA provides robust short-circuit and overload protection. The 1P+NA (Single Pole + Neutral) configuration enables simultaneous disconnection of both live and neutral conductors, ensuring complete isolation during fault events or maintenance. This design enhances safety and compliance with electrical codes, particularly in applications where neutral switching is required. The ST201M-Z10NA is built to meet stringent industry standards, offering reliable performance in standard distribution boards and enclosures. Its compact DIN rail mounting design facilitates easy installation in confined spaces, while the durable construction ensures long-term reliability in challenging environmental conditions. Key specifications include a current rating of 10 A, a tripping characteristic of Z-Char., and a breaking capacity of 10 kA. This miniature circuit breaker is an ideal choice for protecting sensitive electronic loads, control circuits, and power distribution systems where precise overcurrent protection is critical.
