MEGGER B10E Trip Coil Tester

The MEGGER B10E Trip Coil Tester is an essential tool designed for the efficient and reliable testing of circuit breakers. This compact power supply unit stands out in the industry due to its ability to provide a stable and dependable power supply specifically tailored for circuit breaker testing.

Featuring a continuously variable output ranging from 24 to 250 V, either AC or DC, the B10E can adapt to a wide range of testing needs. It ensures that the testing process is not only efficient but also comprehensive, thanks to its separate outputs designated for close coil, trip coil, and spring charging motor voltage. This separation allows for simultaneous testing of different components, streamlining the maintenance process and reducing the time needed for each test.

A notable feature of the B10E is its capability for direct triggering, which is crucial for minimum trip voltage testing. This feature helps in determining the lowest voltage at which a circuit breaker can operate effectively, thereby ensuring that the breakers will function properly under various power conditions.

The B10E is designed to be used alongside a breaker analyzer, enhancing overall testing efficiency. This combination allows for quicker diagnostics and more precise results, making it a valuable setup for routine maintenance and troubleshooting.

Moreover, the B10E excels in situations where auxiliary voltage to circuit breakers is either unavailable or disconnected. It provides a dedicated output for supplying spring-charging motors, which is vital for the proper operation of circuit breakers. The ripple-free variable DC voltage output of the B10E is adept at handling high, variable loads, ensuring that the coils of the circuit breaker are tested thoroughly.
