Description:

The STVP series automatic over-voltage and under-voltage protector is designed for three-phase AC 380V 50/60Hz circuits with a rated working current of 63A or less. It provides reliable protection by instantly disconnecting power during abnormal voltage or current conditions, and automatically restores power when normal conditions return.

Features:

• Over-voltage protection
• Under-voltage protection
• Over-current protection
• Automatic recovery
• Voltage and current digital display
• Three-phase ampere unbalance protection
• Phase sequence (reverse phase) protection
• Zero line break protection
• Phase failure protection
• Fault inquiry memory
• Rotational voltage and current display for each phase
