SENTOP RPQ8-125 Series
Industrial Automatic Transfer Switch (ATS) | CB-Class Dual Power Protection
Industrial-Grade Reliability
The SENTOP RPQ8-125 is a professional-grade CB-class dual power automatic transfer switch designed for AC 50/60Hz industrial systems. Unlike standard PC-class switches, the RPQ8 series integrates short-circuit and overload protection, acting as both a transfer device and a circuit breaker. It is engineered to monitor voltage status in real-time, automatically switching to backup power (generator or secondary grid) to prevent costly downtime. With its high breaking capacity and robust mechanical interlocking mechanism, it is the premier choice for factories, data centers, and critical infrastructure.

Integrated CB Protection
- Overload & Short-circuit: Built-in thermal-magnetic release prevents damage to connected loads during electrical faults.
- High Breaking Capacity: Designed for industrial grids with potential for high fault currents.
- Silver Alloy Contacts: Extra-large silver contact points ensure low temperature rise and 5,000+ mechanical operations.
Advanced Control Logic
- Voltage Monitoring: Detects under-voltage, over-voltage, and phase loss in real-time.
- Mechanical Interlock: Prevents both power sources from being connected simultaneously, eliminating cross-grid risk.
- Auxiliary Contacts: Ready for integration with fire control systems or remote SCADA monitoring.
