Overview

This 1-pole (1P) breaker is rated for 4A with a K-trip characteristic, providing reliable overcurrent protection in 277/480 VAC systems. The K-trip curve offers protection against short circuits and moderate overloads, with a typical tripping current around 1.6 x In for K-type breakers, making it ideal for sensitive electronic equipment and control circuits where precise overcurrent protection is critical. Engineered for rapid installation and maintenance, the SUP401M-K4 features a pluggable design that allows for quick circuit replacement without extensive wiring or specialized tools. This reduces downtime and labor costs in panelboard applications. The breaker is housed in RAL 7035 and includes contact position indication (CPI) and trip position indicator (TPI) for clear status visibility. With a rated interrupting capacity of 10 kA and protection degree of IP20 (IP40 when installed in an enclosure with a cover), it meets stringent performance requirements for industrial and commercial electrical systems. Key specifications include a rated voltage of 480Y/277 VAC, mechanical endurance of 20,000 operations, and electrical endurance of 6,000 operations. The compact dimensions (18 mm width x 102 mm height) and lightweight design (120 g) make it suitable for space-constrained installations. Compatible with the SMISSLINE TP system, this breaker is a critical component for ensuring operational efficiency and safety in electrical distribution systems.
