Key Characteristics & Features
Catalog Base Number (402232): Represents the base hardware model for the VacuFuse interrupter system.
Suffix Configuration (-D5R9-S103): Specifies the factory-programmed options, including the voltage class, BIL rating, and a specific TCC (Time-Current Characteristic) curve (such as K, KS, or T curves) tailored to coordinate with upstream grid devices.
Fault-Testing Capability: Instead of permanently blowing like a standard fuse during temporary disruptions (e.g., animal contact or weather), it tests the line and resets automatically if the fault clears.
Physical Operation: It operates via an internal vacuum interrupter. If a fault is permanent, it locks out and drops open to provide a clear visible gap for utility field crews.
Condition: Incomplete Unit - See Attached Spec Sheet
