ABB S204C16 four-pole miniature circuit breaker with a 16 A rating, C-curve tripping characteristic and 6 kA short-circuit capacity for commercial and industrial electrical protection.
£193.89
The ABB S204C16, also identified as S204-C16, is a premium four-pole miniature circuit breaker (MCB) designed to protect electrical circuits against overloads and short circuits. As part of the trusted ABB System pro M compact S200 series, it provides dependable protection for residential, commercial and industrial electrical installations.
The circuit breaker incorporates a delayed thermal tripping mechanism for overload protection together with an electromechanical tripping mechanism for rapid short-circuit interruption. Its C-curve tripping characteristic makes it ideal for protecting distribution circuits, lighting installations, HVAC systems, control panels and equipment with moderate inrush currents.
With a rated current of 16 A, a four-pole configuration and a rated short-circuit capacity of 6 kA at 230/400 V AC, the S204C16 offers reliable protection for three-phase installations with neutral switching. Its compact modular design enables quick installation on standard 35 mm DIN rails within distribution boards and switchboards.
The ABB S204C16 automatically disconnects electrical circuits whenever overload or short-circuit conditions occur, helping protect cables, equipment and connected installations. Its current-limiting design reduces fault energy, contributing to improved safety and longer equipment life.
Its C-curve tripping characteristic makes it well suited to protecting three-phase distribution systems, lighting circuits, HVAC equipment, machinery and commercial electrical installations where moderate starting currents are present.
