EATON W-VAC Type Shunt Trips
Eaton W-VAC type shunt trips are protective devices that automatically interrupt the electrical current flowing through a circuit when the current or voltage exceeds a predetermined level. These units avoid damage to the electrical equipment and protect people from electrical hazards.

Working Mechanism
- When an overcurrent or overvoltage condition occurs, the trip unit detects the problem and sends a signal to the circuit breaker to open the contacts, thereby interrupting the flow of electrical current.
Frequently Asked Questions
Can I manually reset a shunt trip breaker?
Yes, you can reset a shunt trip breaker by turning off the power to the circuit and then turning it back on.
What is the difference between a shunt trip breaker and a standard circuit breaker?
The main difference between a shunt trip breaker and a standard circuit breaker is that a shunt trip breaker has a separate trip unit connected to the circuit breaker through shunt trip coils, thereby allowing for remote tripping of the breaker for safety or maintenance purposes.
How do I wire a shunt trip breaker?
Wiring a shunt trip breaker involves connecting the shunt trip coils to the circuit breaker & the power source and connecting the trip unit to the shunt trip coils & the control system.
How to install a shunt trip breaker?
Installing a shunt trip breaker involves connecting the shunt trip coil to the control circuit of the breaker and connecting the power and load lines to the appropriate terminals on the breaker.
How to troubleshoot a shunt trip?
- Check for continuity between the shunt trip coil terminals.
- Check the voltage at the coil terminals.
- Ensure that the shunt trip coil is connected properly to the control circuit of the breaker.
