NISI 3 Pole Rotary Phase Changer Switch

The NISI 3 Pole Rotary Phase Changer Switch is an electrical switch designed to change the phase sequence of a three-phase electrical system. It typically consists of three poles, each representing one phase of the system, and allows for manual switching between different phase sequences. The rotary phase changer switch is commonly used in situations where it is necessary to adjust the phase sequence of the electrical supply, such as in industrial machinery, motors, or equipment. By changing the phase sequence, the switch ensures proper synchronization and operation of three-phase equipment, preventing damage and ensuring optimal performance.
