ABB SMISSLINE TP S400E Miniature Circuit Breaker 1-Pole, 8A, Type B, 400V AC, 6kA, DIN Rail 2CCS551001R0085 - S401EB8

ABB 2CCS551001R0085-S401EB8 Miniature Circuit Breaker is engineered for robust protection of electrical circuits in both commercial and industrial settings. The S400E series features a reliable single pole configuration with an 8A current rating, which is ideal for protecting branch circuits and sensitive equipment from overloads and short circuits. The Type B tripping characteristic is suitable for resistive and moderately inductive loads, making it versatile for a range of distribution applications.

This MCB operates reliably at AC voltages up to 400V and achieves a 6kA breaking capacity, enabling it to withstand substantial fault currents without compromising system integrity. Installation is streamlined with its compact 18mm width and DIN rail mount compatibility, making it ideal for panels where space efficiency is a priority. The device incorporates a thermal-electromechanical mechanism that guarantees circuit disconnection during overcurrent events, protecting downstream components and enhancing operational reliability.

The bidirectional cylinder lift terminal configuration reduces installation complexity and ensures firm connections. Its IP20 rating guards against accidental contact and offers basic protection from foreign objects in typical panel environments. Compliance with EN 60898-1 standards ensures safe performance and quality assurance in industrial and commercial installations.

Typical applications include integration into automated industrial systems, light and heavy-duty commercial installations, plug-in distribution boards, and environments requiring reliable performance under load. It is also compatible with Smissline products, offering enhanced integration capabilities for modular distribution systems. Maintenance involves routine inspection of connections and periodic testing of tripping mechanisms, ensuring continued operational integrity.
