SUP402M-K20

The SUP402M-K20 features a K-type tripping characteristic, meaning it trips at 1.6 times its rated current (In) at a reference temperature of 25°C.

The SUP402M-K20 is rated for 480Y/277V AC systems. It also supports 250V DC (1P) and up to 500V DC (2+4P) under pollution degree 2 conditions.

This circuit breaker has a short circuit rating of 100kA at 240V, 100kA at 480V, and 35kA at 600V.

Yes, the SUP402M-K20 is specifically designed for and compatible with the ABB SMISSLINE TP System for modular panel building.

The K tripping characteristic is suitable for circuits with moderate inrush currents, such as inductive loads, balancing delayed tripping for inrush with rapid short-circuit protection.

Yes, the SUP402M-K20 includes auxiliary contacts, allowing for signaling and remote monitoring.

The rated current (In) for the ABB SUP402M-K20 miniature circuit breaker is 20A.

The SUP402M-K20 is rated for Overvoltage Category III.
