Product Details

MPRO-50 GE(AEG) trip unit M-PACT Air circuit breaker GE(AEG) ACB

Specifications:

A line offering a new range of electronic trip units designed to extend and/or upgrade the functionality offered by the existing M-PACT Plus air circuit breaker.

Two types are available. The simple and effective MPRO-27 and the MPRO-50 offering extended functionality Each has a LCD screen with ammete r and a menu driven setting interface, allowing a simple and accurate setting of all parameters.

This global line of electronic trip units uses the most recent technology to offer each user an unique combination of selectivity speed and functionality.

Main Adjustment Options

LT-LTD protection

Each device has an overload setting range of 0.4 to 1 times In and offer a choice of 22 time bands designed for use with circuit breakers. A second set of 22 time bands shaped to match the time current curves of fuses is available on the MPRO-50 type.

ST-STD protection

A timed delayed short circuit protection are installed with a current setting of 2 to 12 times the set LT current value. The short circuit protection time can be set, at one of 17 bands ranging from 90 milliseconds to 1 second.

I-protection

A switchable and selective instantaneous protection with a setting range of 2 to 15 times the breaker rating that is programmed to wait one half cycle until the downstream device has reacted.

Other protection features

A host of other protection devices are available including: Ground Fault sum and Ground Fault source return (allowing UEF, SEF & REF) and a reduced instantaneous device. The reduced instanataneous device allows the user to conditionally programme the breaker to trip faster and at lower short circuit settings than it would on the standard instantaneuos device.

This RELT device allows the user to reduce the short circuit current level and its time span, thus reducing the amount of electrical energy in the direct vicinity of the breaker.
