The S800P series from ABB offers a top-class compact solution for line protection up to 50 kA, with expandability for the most challenging, highly demanding requirements across diverse industries. Ettienne Delport, Vice President and Channel Manager for Smart Buildings and Smart Power, ABB Electrification, emphasises: “It combines size and performance to protect customers’ installations.”
Due to its intrinsic characteristics and the range of available accessories, the S800P series is suitable for different types of applications in railways, data centres, telecommunications, renewable energy, and general industrial installations. The miniature circuit breaker guarantees safe electrical isolation of the circuit in compliance with IEC 60947-2. The range was designed with specific materials for traction and classified with a R26/HL3 hazard level in accordance with EN45545-2. The plastic materials used also comply with fire and smoke requirements according to EN45545-2.
The S800P range offers high-rated current protection (80 A, 100 A, 125 A) at a high breaking capacity level up to 50 kA. It is available in all pole configurations (1P, 2P, 3P, 4P) and B, C, D, K tripping curves.
In rail applications, in addition to the requirements for high quality and anti-flammability protection, compliance to vibration and shock resistance also needs to be built in. The S800P has been successfully tested according to IEC 61373 for Rolling stock equipment – Shock and vibration tests: Category 1/Class B.
The mechanical drive of the S800P is equipped with a trip-free release. The trip position display reliably indicates the exact position of the moving contact. It also provides additional trip detection allowing for easy identification of the reason for any cut-off. The switch lever moves to the middle position in case of thermal or magnetic tripping.
The circuit breaker is supplied with an interchangeable terminal adapter for wires, cables, and rigid conductors, which guarantees a high level of flexibility and comfort. Fast and safe connection of the conductors is ensured by the integrated onboard terminal shutter that prevents incorrect under-clamping of the connections.
The S800P functions as a protection device and allows for remote control and monitoring of the installation. Accessories to extend its functionality include auxiliary contacts, aux/signal contacts, remote switching unit, short circuit limiter, shunt operation releases, undervoltage releases, RCD block, and busbars.
The S800 range of high-performance micro circuit breakers presents a suitable choice for heavy duty industrial and renewable energy applications. With the innovative short-circuit extinguishing technology, S800 devices offer a solution where the combination of size and performance are required. They provide an alternative to main fuses in diverse applications.
