General Electric THC31 Fusible Disconnect Switch

The General Electric THC31 Fusible Disconnect Switch is a 30A, 3-phase disconnect device designed to safely isolate a 600V circuit in industrial and commercial electrical systems. As a fusible disconnect, it contains replaceable fuses that open the circuit to interrupt current on faults, providing a clear local shutoff point for service or maintenance and enabling safer troubleshooting and equipment servicing. Rated for 600V in three-phase power networks, the THC31 supports applications where a fused disconnect is required to protect conductors and equipment while allowing quick de-energization when needed. It is designed to be integrated into power distribution schemes and control panels where a dedicated disconnect switch is specified, offering a compact form factor that fits into standard enclosures. Because the fuses are replaceable, the unit can be restored to service after a fault without replacing the entire switch, supporting straightforward maintenance. This GE device focuses on reliable operation and practical installation, delivering a sensible solution for isolating a branch circuit in compliant electrical installations.
