Can Eaton VCP-W vacuum circuit breakers be used in harsh working environments?

These circuit breakers feature tin-plated poles to withstand harsh environment applications.

Where are undervoltage relays used?

They are used in alternators, motors and busbars.

By reducing the system impedance.By reducing the line current.

Eaton VCP-W-Series undervoltage relays are used with the brand's VCP-W vacuum circuit breakers to prevent short circuits and voltage drops.

When a relay's coil voltage drops below a set threshold, an under-voltage relay comes into action.
Under-voltage relays shield loads from voltage drops that could cause brownouts and power outages.
When the voltage drops below a specific point, the relay contacts trip the circuit breaker.
