Schneider Electric LV848261

The basic frame for the MasterPact MTZ2 12L1 is designed for use with a drawout circuit breaker, supporting a rated current of 1250A at 40°C. This circuit breaker frame is suitable for three-phase systems and is compliant with international standards such as IEC/EN 60947-1 and IEC/EN 60947-2.

The frame is engineered to handle a maximum operational voltage of 690VAC and features a breaking capacity of 150kA at both 415VAC and 440VAC under 50/60Hz conditions, with a rated insulation voltage of 1000V. Additionally, it is constructed to endure a mechanical durability of 25000 cycles with periodic maintenance and an electrical durability of 3000 cycles at 690VAC.

This basic frame must be paired with the appropriate chassis and control unit, which are not included and need to be ordered separately. The MicroLogic X control unit offers enhanced functionality and can be integrated into EcoStruxure architecture systems.

Dimensions of the frame are 441mm in width, 439mm in height, and 403mm in depth when equipped with a chassis, while the depth without chassis is 300mm. This configuration allows for flexibility in installation, and the unit is suitable for both front and rear connections.
