View Full Specs

The Vanguard MCCB-500-2 is a microprocessor-based high current circuit breaker test set. This unit provides a variable high current source, control, metering, and timing circuitries for testing overload relays and thermal and magnetic circuit breakers. The MCCB-500-2 high output current source can also be used in other primary current injection applications.
The MCCB-500-2's current source has 3 outputs: 500A @ 4 Vac, 125A @ 14Vac, and 25A @ 70Vac.  The current sources can output short-duration overload conditions. This feature is convenient for performing instantaneous trip tests of molded case circuit breakers, or testing the time delay characteristics of magnetic overload relays.
Test current is measured and displayed on a 128 x 64 pixel back-lit LCD screen that is clearly visible in direct sun light or low light levels. Control switches are used to turn the current source on and off, select the timer stop input type (current mode, dry contact, or wet contact), and control the LCD contrast.
A "momentary" mode can turn on the current source, capturing the current reading and displaying the value on the LCD. This feature can be used to set the test current and minimizes the possibility of overheating the device under test.
Test current is turned on at the zero crossing point using a solid state device for reliability and precision timing.
