LA9LB920 and GV1L3 current limiter are dedicated to Tesys GV2 Motor Protection Circuit Breaker (MPCB) product range and can be used with MPCB rated up to 32A (maximum current range of Tesys GV2 products). The new Tesys GV3 range does not have current limiter to increase its breaking capacity. If higher breaking capacity for Tesys GV3 is needed, use in association with fuses can increase the breaking capacity of the system up to the fuse performance breaking capacity.

The first black arrow needs to be set at the rated current of Motor, when Tesys GV3 MPCB is used with contactor separately mounted or not used at all. The second white arrow needs be set at rated current of Motor, when the Tesys GV3 MPCB and contactor are used in combination. This setting gives allowance for the heat dissipation in the thermal characteristics of MPCB due to the combined use of the Tesys GV3P and Tesys LC1D at the rated current. See below diagram for clarity.
