The ABB S401M-UCZ63 is a compact single-pole miniature circuit breaker (MCB) designed to protect electrical circuits against overload and short-circuit currents in DC and AC applications. As part of the ABB SMISSLINE TP S400M UC series, it combines dependable circuit protection with the installation flexibility of ABB's pluggable SMISSLINE TP distribution system.
The S400M UC range extends ABB's established SMISSLINE TP platform to direct-current applications while retaining AC/DC versatility. The S401M-UCZ63 is suitable for single-pole DC applications up to 220 V DC and integrates directly with compatible SMISSLINE TP socket-base assemblies, supporting efficient installation, replacement and system expansion.
With a rated current of 63 A, a Type Z / UC-Z tripping characteristic and a rated short-circuit capacity of 10 kA, the S401M-UCZ63 provides sensitive overcurrent protection for demanding distribution and equipment circuits. Its rated ultimate short-circuit breaking capacity reaches 20 kA Icu at 220 V DC, and the breaker carries ABB order code 2CCS571001R1638.
The ABB S400M UC range extends the SMISSLINE TP miniature circuit-breaker platform to DC and AC applications. The S401M-UCZ63 combines thermal overload protection with rapid short-circuit protection in a compact single-pole format, helping protect conductors and connected equipment against potentially damaging overcurrent conditions.
Its Type Z / UC-Z characteristic is intended for sensitive circuits where the magnetic release needs to respond at a comparatively low multiple of rated current. Together with its 20 kA Icu capacity at 220 V DC and ABB's SMISSLINE TP plug-in architecture, the S401M-UCZ63 provides robust protection for higher-current DC distribution, industrial control and equipment circuits.
