SIBA GmbH products

Power stations, substations, overhead power lines: Of the many energy utility installations that ensure our vital electricity supply, most people only take notice of the big, visible features. As far as many consumers are concerned, electricity still simply comes out of the wall. But that things are far from that simple is a story the energy utilities could tell every day.

SIBA offers a comprehensive range of ultra-rapid fuses designed to protect sensitive power semiconductors used in converters, thyristors, and uninterruptible power supplies (UPS) from short-circuit currents. This range, known as `Ultra-rapid`, ensures the high-speed disconnection of the power supply to safeguard semiconductors against potential damage. Such protection is crucial given the delicate nature of these devices. SIBA`s fuses are engineered to maintain their reliability even under constant operating loads, thereby extending the operational lifespan of the semiconductors. Their applications include, but are not limited to, photovoltaic systems, energy storage solutions, and frequency converters. The fuses are suitable for various scales, from small domestic installations to large solar farms and modern battery systems, meeting stringent requirements with breaking capacities exceeding 100 kA.

SIBA`s low-voltage fuses are critical components designed to protect electrical systems and equipment from damage due to overcurrent. These fuses act as a barrier, preventing potential downtime, costly repairs, and operational interruptions that can arise from equipment failure. Ideal for use in industrial machines and home installations, SIBA NH fuses offer reliable protection against faults and poor workmanship during wiring installation. The comprehensive range includes various sizes and voltages, ensuring compatibility with numerous applications from domestic pre-fuses to industrial machine tools. The innovative combination indicator feature enhances user convenience by providing clear and dependable status indication both at the top and center of the fuse, significantly reducing the time needed to identify and replace blown fuses.
