TH4321

Description

The GE TH4321 and ABB TH4321 are 30A 3-pole heavy-duty fusible safety switches specifically engineered for indoor safety and disconnect applications. These switches are designed to provide reliable performance in commercial and industrial environments, where safe and efficient power management is critical.

With a 240-volt rating, these switches are ideal for low to medium-power systems requiring a secure and robust disconnect solution. The GE TH4321 and ABB TH4321 are designed to handle a maximum interrupting rating of 200 kiloamperes at 240V, ensuring protection against electrical faults such as short circuits and overcurrent conditions. Their fusible design allows for the use of Class R fuses, which provide additional protection and help to minimize downtime by offering easy maintenance and replacement options.
