3-Phase Rotary Switch Adaptor for MT328 - Major Tech

Features :

• Allows for standard 4mm test leads to be connected to the MT328 and any type of Industrial plug to be connected to the open ends of the cable.
• Once the plug has been inserted into the industrial socket, one can begin the test.
• The rotary switch on the side is where the user can select L1, L2 or L3 of 3-phase circuits for testing.

DESCRIPTION

The MT319 is a 3-Phase Rotary Switch Adaptor for MT328.

The MT328 is a powerful meter when used for testing Industrial Earth Leakage devices. The test procedure is quite simple when performing tests on the open terminals between L1 and Earth, L2 and Earth and L3 and Earth as the test leads can simply be connected to each phase. Simply connect the black lead with the crocodile clip to the Earth terminal and the Red prod to the Phase terminal under test, the test button can then be pressed to either determine the trip time or the mA leakage current.

However in more industrial applications where an ELCB test needs to be performed on Industrial sockets etc, where there are 3-phase circuits, it is cumbersome to try perform the test due to space issues plus encountering the spring loaded cover of the socket, for this reason the MT319 3-Phase Socket Adaptor was developed. The MT319 allows for standard 4mm test leads to be connected to the MT328, and any type of Industrial plug to be connected to the open ends of the cable. Once the plug has been inserted into the industrial socket, one can begin the test. There is a rotary switch on the side of the MT319 where the user can select L1, L2 or L3 of 3-phase circuits for testing.

Where a number of different industrial plugs are required for different testing purposes, one can simply use more MT319 adaptors. The MTKBAG Heavy Duty Meter Bag is the
