The Vanguard CT-6500 Circuit Breaker Timer

  • Uncategorized

Circuit breakers need constant testing because of their critical role in an electrical system. They need to interrupt large currents to protect the electrical system from failing due to overloads or short circuits. If a circuit breaker fails to trip the current, the damage could be disastrous.

circuit breaker timer is a testing tool used to measure a circuit breaker’s trip response time and the time it takes a contact to travel to open position. Vanguard is one of the leading manufacturers of circuit breaker timers. One of its widely used testers is the CT-6500. It features a slow-close test which measures the travel time of a breaker’s contacts accurately. It can monitor trip or close coil current and it has three transducer channels for measuring a circuit breaker contact’s bounce back, over-travel, stroke and velocity. You can also measure 3 poles all at the same time. It is possible to use it as a stand-alone device or via USB or RS 232 interface so you can control it through a computer. This tester features a built-in thermal printer so you can print test results for documentation.
