Mismatch Protection
Description
Mismatch protection allows the installation of a MasterPacT MTZ1 circuit breaker only in a chassis with compatible characteristics.
Mismatch protection offers 35 different combinations that can be selected so that a circuit breaker can only be mounted on a chassis with the matching combination.
Accessory
The use of mismatch protection is optional. One mismatch protection accessory is required for each circuit breaker.
For information on the accessory installation, consult the instruction sheet available at Schneider Electric website: NVE35465.
Pin Location of Mismatch Protection
The following illustration shows the pin location on the chassis and circuit breaker, respectively.
The pin combination selected on the chassis must correspond to the pin combination selected on the circuit breaker (see following table). For example, the combination 12 on the chassis corresponds to the combination CDE on the circuit breaker.
Pins on the chassis are labeled 1, 2, 3, 4, 5.
Pins on the circuit breaker are labeled A, B, C, D, E.
