Why Miniature circuit breakers?

Electrical consumption in residential and commercial buildings continues to grow, increasing the risk of overloads or short circuits. In the event of overload or short-circuit, SENTRON miniature circuit breakers (MCBs) safely cut the connected circuit, protecting cables and lines.

MCBs reliably protect electrical systems and equipment, preventing costly production downtimes and economic losses. They’re especially essential in high-demand applications like data centers or the automotive and semiconductor industry, to meet the enhanced requirements of complex and increasingly automated buildings and applications.

Key benefits

Keep up with new demands

The growing number of electrical devices and automated operating procedures increase demands on systems. MCBs from the SENTRON portfolio meet the enhanced requirements of automated buildings and industrial power supply systems. 

Enable backup protection

SENTRON MCBs protect wires and cables in cases of short circuit and overloads and offer backup protection for switching devices and semiconductor protection. They’re a fundamental component for end-to-end protection. 

Help protect your workers

MCBs can help protect humans against electric shock when combined with RCCBs or used as RCBOs. Combining the 5SY MCB with the 5SM6 arc-fault detection unit (AFDD) further expands the range of functions.
