Schnellsicherung RGS4 is a fast-acting circuit protection device engineered to prevent damage from overcurrent events. It is offered in the following current ratings: 32A, 40A, 50A, 63A, 75A, 80A, 85A, 100A and 110A. Key benefits — why you need it and how it helps Rapid trip protection: fast-acting behavior limits the energy let-through during a fault, reducing damage to wiring, components and connected equipment. Accurate sizing options: multiple ratings let you match protection to the load and minimize nuisance trips while maintaining safety. Space-efficient design: compact form factor simplifies integration into control panels and tight enclosures. Industrial-grade durability: robust construction withstands demanding environments and frequent service cycles. Easy replacement and maintenance: straightforward swap-out reduces downtime and keeps systems operational. Important attributes Function: fast-acting overcurrent protection for electrical circuits to prevent component and wiring damage during short circuits or overload spikes. Compatibility: available ratings cover typical control circuits, power distribution and motor/drive applications. Size and form factor: compact for installation in confined panel spaces and for use in modular equipment layouts. Material and construction: built for industrial use with a durable design appropriate for repeated operation and replacement. Performance: reliable, predictable trip behavior at the selected rating to provide consistent protection and reduce troubleshooting time. Practical applications Manufacturing machinery: protect machine control panels and motor drives on production lines from fault currents that could damage drives, relays and wiring. Renewable energy and charging systems: guard solar inverter inputs, battery charge/discharge circuits and DC distribution from overcurrent events. Power and telecom equipment: shield power supplies in data centers, telecom racks and industrial automation systems to preserve uptime and protect downstream electronics. Selection guidance Choose the rating that matches your normal operating current with an appropriate margin for inrush or temporary loads to ensure safe, reliable protection and minimize unnecessary trips. Schnellsicherung RGS4 provides fast, dependable overcurrent protection across a broad range of common current ratings, combining compact installation, rugged construction and predictable trip performance for industrial and commercial applications.
