Overview

The ABB SUP401M-K6 is a UL 489-listed miniature circuit breaker (MCB) designed for the SMISSLINE TP system, providing reliable branch circuit protection in 277/480 VAC systems. This 6A, K-type breaker is optimized for applications with higher inrush currents—such as motors, transformers, or inductive loads—where standard B or C characteristics may cause nuisance tripping. The K-type tripping characteristic ensures rapid response to overloads while minimizing false trips during startup surges. Engineered for the SMISSLINE TP modular platform, the SUP401M-K6 features a pluggable design for simplified installation, maintenance, and system reconfiguration. Its plug contacts are field-reconfigurable between L1, L2, and L3 phases, enabling flexible arrangement without rewiring. An integrated inspection window provides clear phase indication, while the IP20 touch-safe housing prevents accidental contact with live components. Key specifications include a rated interrupting capacity of 10 kA (UL 489 compliant), electrical endurance of 6,000 operating cycles, and mechanical endurance of 20,000 cycles. The device operates at a reference tripping temperature of 40°C and supports auxiliary/signal switches (e.g., S2C-H6RU or S2C-S6RU) for expanded functionality. Housed in an RAL 7035 gray enclosure with a black, sealable toggle, the SUP401M-K6 meets UL 489 standards for supplementary protection in general-use applications. Ideal for industrial control panels, distribution boards, and machinery protection, the SUP401M-K6 integrates seamlessly with the SMISSLINE TP system’s 1P (277V AC) or multi-pole configurations (480Y/277V AC). Its compact design and compliance with UL 489 make it a dependable choice for branch circuit protection in commercial and light industrial environments.
