Molded Case Circuit Breakers with Measuring Display Unit

Molded Case Circuit Breakers with Measuring Display Unit

Measuring display unit (MDU) breakers are a combination of circuit breaker, measuring device and display that make it possible to measure, display and transmit information about electric circuits while simultaneously supporting energy savings by small space and short installation time. The MDU breakers have compact design with the LCD screen for displaying circuit information embedded on the front of its body.

Construction cost saving and Space saving

• Wiring work for measuring devices is unnecessary, and the construction period and cost can be reduced.
• The panel installation area can be reduced, and the space can be effectively used. After MDU breaker is introduced upgrading can be expected by adding the measuring and display functions within the area of the standard circuit breaker.

Multifunctionality

1.Uses

(1)MDU circuit breakers are capable to clarify the relationship between production volume and power usage as well as a tool for visualizing collected data.

2.Effect of installation

(1)Automation of periodic measurement

• Automatic measurement by the hour
   Daily manual measurement requires to read and record the values measured at many points and enter the values into a personal computer.

(2)Automation of detailed measurement

• Detailed measurement of electric power in specific equipment (for example,measurement every 15 minutes for 1 week) can be automated through setting on a personal computer.

Downsizing

Breakers with the same outside dimensions as the standard circuit breakers are realized by using the front LCD for displaying circuit information.

Visibility

When an alarm or fault occurs,the LCD backlight changes from white to red.

Operability

The multi-function display screen reduces the number of operations.

Breaking capacity

Various types of mounting
