Overview

The ABB SUP401M-K20 is a UL489-certified miniature circuit breaker designed for 277/480 VAC systems, featuring a 20A rated current and a K-characteristic tripping curve. This pluggable breaker is specifically engineered for the SMISSLINE TP System, ensuring compatibility with panelboards, distribution boards, and control panels. Its modular pluggable design facilitates quick replacement without impacting adjacent circuits, minimizing downtime during maintenance or upgrades. The K-curve tripping characteristic provides rapid response to overloads and short circuits, safeguarding sensitive equipment. Manufactured by ABB, the SUP401M-K20 offers reliable performance in industrial, commercial, and infrastructure applications. Compliance with UL489 standards guarantees adherence to safety and performance requirements for low-voltage circuit protection. Key specifications include a rated voltage of 277V AC (1P) or 480Y/277V AC (2-4P), and a rated interrupting capacity of 10 kA. The reference tripping temperature is 40°C. Mechanical endurance is rated at 20,000 operations, with shock resistance at 25g. Electrical endurance is 6,000 operations with a 1s ON/9s OFF cycle. The housing offers IP20 protection (IP40 with cover). Contact position is indicated by a real CPI (green OFF/red ON), and a trip position indicator (TPI) is present (gray NO TRIP/orange TRIP). The toggle is black, sealable, and constructed from insulation group II materials. Applications include supplementary protection for general use in panelboards, distribution boards, and control panels, particularly in environments requiring UL489 compliance such as manufacturing facilities, data centers, and renewable energy systems.
