Comparison with VPR-33-02A
While both the VPR-33-00 and VPR-33-02A are designed to provide reliable protection against voltage disturbances in three-phase systems, the VPR-33-02A offers enhanced functionality:
- VPR-33-00 → Reliable basic voltage protection (single relay).
- VPR-33-02A → Advanced version with dual relays + frequency monitoring for more demanding industrial and generator-based applications.
