Why Choose the ABB S203-D6 Miniature Circuit Breaker?
The ABB S203-D6 is a dependable three-pole miniature circuit breaker (MCB) engineered to provide reliable protection against overloads and short circuits in commercial, industrial and OEM electrical installations. As part of the renowned ABB System pro M compact S200 series, it combines robust performance with compact dimensions for modern electrical distribution systems.
Designed with both a delayed thermal tripping mechanism for overload protection and an electromechanical tripping mechanism for rapid short-circuit interruption, the S203-D6 delivers dependable circuit protection in demanding applications. Its D tripping characteristic makes it particularly suitable for protecting circuits with high inrush currents, including electric motors, transformers, solenoids and other inductive loads.
With a rated current of 6 A, a three-pole configuration and a rated short-circuit capacity of 6 kA at 400 V AC, the ABB S203-D6 is ideal for safeguarding three-phase circuits. Its compact modular construction enables quick installation on standard DIN rails within electrical panels and switchboards.
