General Electric TH4321R Fusible Safety Disconnect Switch

The General Electric TH4321R Fusible Safety Disconnect Switch is a fusible disconnect designed to safely isolate three-phase power, combining disconnection and protection in a single enclosure. It is rated for 30 A at 240 VAC in a 3-pole, 3-phase, 4-wire configuration, making it suitable for controlling standard three-phase loads wired for 240 VAC. The enclosure carries a Type 3R rating, indicating outdoor-appropriate protection for installations exposed to weather. This device provides a practical means to interrupt power to motors or other three-phase equipment while accommodating fuse-based protection in the circuit. Designed for robust outdoor or semi-outdoor applications, the TH4321R supports reliable operation in environments where weather exposure is a concern and where a code-compliant disconnect is required for safety and maintenance access. With a 4-wire configuration, it accommodates grounded systems and aligns with standard three-phase distributions.
