Built for Safety. Engineered for Reliability.
At Mine Power, we prioritize safety in every panel we build. Our Electrical Changeover Panels are equipped with advanced protection systems to ensure safe and uninterrupted operation in demanding mining environments.
1. Overload Protection
Prevents damage to equipment caused by excessive current.
Implemented using thermal overload relays, MCBs, or MCCBs.
2. Short Circuit Protection
Instant trip mechanisms protect the circuit from high fault currents.
Achieved through fast-acting circuit breakers and fuse links.
3. Earth Fault Protection
Monitors leakage current and disconnects supply in case of insulation failure.
Integrated Earth Leakage Circuit Breakers (ELCBs) or Residual Current Devices (RCDs).
4. Phase Failure & Phase Sequence Protection
Detects phase loss or incorrect phase sequence to prevent equipment damage.
Uses phase monitoring relays with visual and audible alarms.
5. Mechanical & Electrical Interlocking
Prevents simultaneous connection of mains and generator power.
Ensures safe and secure transition between sources.
6. Under/Over Voltage Protection (Optional)
Automatically disconnects load during unsafe voltage conditions.
Protects sensitive equipment from voltage fluctuations.
