Technology company and pioneer in electricals, ABB launched its new industrial miniature circuit breaker (MCB) almost 100 years since it brought the first such device to market.

The new ABB S300 P Industrial MCB updates the fundamental component of a modern electrical system, improving safety, performance, efficiency installation, and information accessibility.

enhanced performance

The upgrade allows for a new level of enhanced performance within the same familiar volume and design for industrial MCBs.

The new generation S300 P, which replaces the previous S200 P, offers new functionalities including the TPI, the Dual DIN-rail clip, and a QR code for quick access to documentation, certificates, and technical data.

performance, safety, and efficiency

MCB is safe, smart, and sustainable building electricals and we can say that S300P will demonstrate technical performance"

Christian Völker, Global Product Manager in ABB Electrification’s Smart Buildings division said, “We know how important an MCB is to safe, smart, and sustainable building electricals and we can confidently say that S300P will demonstrate best-in-class technical performance in the market."

"This new MCB series is market-leading collectively across performance, safety, and efficiency, and ease of installation.”

S300 P

The new S300 P has an updated terminal design to support larger cables, up to 35 mm2, and saves installation space by being one module in width in combination with a bottom fixed auxiliary contact.

It also operates in a more energy-efficient way, with increased impulse withstand voltage and lower internal resistance reducing power loss and increasing safety. The new industrial MCB is useable worldwide and supported by relevant global certifications.

ISO 14025 compliance 

The S300 P is the first MCB to be assessed according to ABB’s circularity products framework and applied with the Company's EcoSolutions™ label, for full transparency on the environmental impact throughout the product life cycle. 

As a precondition, the product has also been externally verified through Type III Environmental Product Declarations (EPD), in compliance with ISO 14025 and support of global requirements from customers and regulators for more sustainable supply chains.
