RGS7 fastacting fuse for voltage systems is designed to protect electrical circuits operating at 690V to 700V. Available in multiple current ratings, it provides precise overcurrent protection while supporting reliable operation in demanding industrial environments. Key benefits Fastacting overcurrent protection: quickly interrupts fault currents to minimize damage to power equipment and wiring. voltage compatibility: suitable for systems rated around 690V to 700V, helping to safeguard HV infrastructure. Flexible current options: offered in 200A, 250A, 300A, 315A, 350A and 400A variants to match specific load and protection requirements. Robust and reliable: designed for industrial use with durable construction to withstand demanding operating conditions. Easy replacement: part of the RGS7 family, enabling straightforward integration into standard voltage fuse applications. Key attributes Model: RGS7 Type: fastacting fuse Voltage rating: 690V to 700V Current ratings: 200A, 250A, 300A, 315A, 350A, 400A Form factor: voltage fuse suitable for standard RGS7 series configurations Material: not specified in the listing; designed for voltage fuse applications Performance: rapid response to overcurrent conditions to protect downstream equipment Applications and use cases Industrial drive protection: safeguard variable frequency drives and motors connected to HV 690–700V networks, preventing damage from short circuits or overload events. Power distribution panels: protect bus bars and feeders in voltage electrical enclosures within manufacturing facilities or processing plants. HV equipment protection: integrate into switchgear, inverters, or HVDCrelated assemblies requiring fastacting protection at 690–700V. Notes Choose the current rating that corresponds to the protected load's maximum continuous operating current plus appropriate margin. Suitable for environments compatible with ringfinger or plugin voltage fuse holder configurations in the RGS7 family.
