Overview

The ABB SUP403M-K20 is a UL 489-listed miniature circuit breaker designed for the SMISSLINE TP System, delivering reliable overcurrent protection in 277/480 VAC systems. This pluggable breaker features a K-trip characteristic (1.6 x In), optimized for applications with moderate inrush currents such as motors, transformers, and inductive loads. With a rated current of 20A, it provides supplemental protection for general use while ensuring compatibility with the SMISSLINE TP System’s modular architecture. Rated for 480Y/277 VAC three-phase systems with a grounded neutral, the SUP403M-K20 offers an interrupting current rating of 65 kAIC at 480V, ensuring robust fault protection in industrial and commercial environments. The breaker supports auxiliary contacts for remote monitoring and includes a bell alarm function for immediate fault indication, enhancing system reliability and maintenance efficiency. Manufactured in the US by ABB - Electrification (SKU: SUP403M-K20), this breaker is built for efficient installation and maintenance due to its pluggable design, allowing quick replacement without disrupting adjacent circuits. This minimizes operational downtime and simplifies system upgrades. The unit meets Overvoltage Category III requirements, ensuring safety in transient-heavy environments, and has a rated insulation voltage Ui of 500 V DC with pollution degree 2, indicating reliable performance in moderate contamination conditions. The reference temperature for tripping characteristics is 25 °C, ensuring consistent operation under standard conditions.
