Megger (formerly Multi-Amp) DDA-1600
The MUL-DDA-1600 replaces the MUL-CB9116, is a 3 module solution consisting
Module 1- Controller and instrumentation module contains all the control
circuitry and instrumentation needed to manually test low voltage circuit
Module 2- Power module contains the course and fine current controls, along
with the SCR initiate package.
Module 3- Output module contains the high current output transformer and the
Input: 460V +/- 5% Input single phase Voltage
Frequency: 60Hz input
Output: 1,600A maximum continuous current
19,200A maximum current through air-frame circuit breaker
14,400A maximum current through molded-case circuit breaker
The unit delivers the rated continuous current for a 24 hour period.
The maximum current available from the test set is determined primarily by the
test circuit impedance. The duration of the available current is determined by
the thermal conditions within the test set.
The maximum current through an air-frame circuit breaker is the maximum
current the test set can deliver through a breaker connected with stabs.
Stabs MAY be required. See MUL-CBS1,MUL-CBS2,MUL-CBS3,MUL-CBS7, for selection.
The maximum current through a molded-case circuit breaker is the maximum
current the test set can deliver through a breaker connected with 5ft cables
The unit comes complete with all interconnect cables listed:
Input leads, 15ft(4.5m), 4AWG 2ea PN 17165
Ground lead, 8in.(45.7cm) 1ea PN 15067

Applications include verifying the ratio of current transformers and testing
thermal or magnetic motor overload relays. In the series configuration, the
higher voltage output of the MUL-DDA1600 permits ready use in substations for
primary injection testing of high voltage circuit breakers and protective
