Advantages of installing current transformers on side-mounted circuit breakers
1. Integrated design: Installing the current transformer directly on the circuit breaker makes installation and wiring easier, reducing additional installation space and costs.
2. Instant response: Directly monitoring the current near the circuit breaker can respond to fault conditions more quickly, improving the protection speed and accuracy of the system.
3. Reduced interference: Reduced interference and attenuation in the signal transmission path, improving the accuracy of the measurement.
