Key benefits Protects equipment across a wide voltage range: rated for 380 / 660 / 690 / 700 / 800 / 1000 V. Flexible current protection options with RGS4 series: choice of 2 A, 63 A, or 125 A to match circuit requirements. Includes a Sicherungseinsatz (fuse insert) option: 2 A, RGS41000 V, providing a defined low-current protection element. Clear, application-ready ratings reduce selection errors and simplify inventory management for installers and maintenance teams. What it does (function) Provides overcurrent protection using the RGS4 family and compatible fuse inserts. The RGS41000 V fuse insert is specified at 2 A for applications requiring a 2 amp protective element at 1000 V. Enables selective protection by offering multiple current ratings (2 A, 63 A, 125 A) within the same product family. Compatibility and performance Voltage compatibility: designed for use in systems operating at any of the listed voltages (380 / 660 / 690 / 700 / 800 / 1000 V). Current options: RGS4 available in 2 A, 63 A, and 125 A configurations to suit different circuit sizes and protection levels. The Sicherungseinsatz 2 A, RGS41000 V is specifically rated for 2 A at the 1000 V level. Intended for standard electrical protection roles where the specified voltage and current ratings match system requirements. Key attributes Function: overcurrent protection via RGS4 series fuses and fuse inserts. Compatibility: supports multiple system voltages up to 1000 V and multiple current ratings (2 A, 63 A, 125 A). Models/specifications: RGS4 family; Sicherungseinsatz (2 A, RGS41000 V); RGS41000 V rated at 2 A. Performance: selectable protection levels permit coordinated protection schemes across distribution circuits. Practical use scenarios Industrial distribution panels: use RGS4 units (63 A or 125 A) to protect feeder circuits while keeping spare 2 A inserts for control circuits. Renewable and high-voltage DC/AC systems: the 1000 V rating and the RGS41000 V 2 A insert suit inverter inputs or high-voltage strings that require defined low-current protection. Motor control and control circuits: use the 2 A RGS41000 V Sicherungseinsatz for sensitive control electronics and the 63 A/125 A RGS4 units for motor feeders. Ordering / specification checklist Voltage ratings supported: 380 / 660 / 690 / 700 / 800 / 1000 V RGS4 current options: 2 A, 63 A, 125 A Sicherungseinsatz included/available: 2 A, RGS41000 V Confirm RGS41000 V current value: 2 A Notes for selection Match the chosen RGS4 current rating to the conductor and equipment protection requirements for proper coordination. Use the RGS41000 V Sicherungseinsatz where a 2 A, 1000 V-rated fuse insert is specified. Verify system voltage against the listed ratings before installation.
