Test Essential Circuit Breaker Parameters with the Doble TDR900 and TDR9000 Testers

Circuit breakers are protective devices that interrupt current when an overload occurs. These devices have replaced fuses in protecting the electrical system. Circuit breakers can easily be reset back to closed position. They can be reused several times and this also reduces down time. It is important to keep circuit breakers in good condition to ensure safe and reliable operation. 

Circuit breaker contacts are prone to problems like carbon deposits because of the arcs formed when the contacts break. There are also times that when the arc is too intense, the contacts weld together. This can be very dangerous because if the current in the electrical line fluctuates to dangerous levels, the circuit breaker may not trip and cause the electrical system to fail.

circuit breaker test set can help you effectively test protective devices by measuring the timing and motion of the mechanism. It simulates electrical system conditions and determines if the circuit breaker will respond properly. If you are looking for a good tester, you might be interested in the Doble TDR900 or the Doble TDR9000 test set. These testers provide accurate and efficient testing of dynamic timing and mechanism motion of circuit breakers. Read on for a comparison of the two models.
