Convention

In this guide, the term MasterPacT MTZ device covers circuit breakers and switch-disconnectors.

Circuit Breakers

The following performance levels (Icu at 415 Vac) are available:

• H1: standard short-circuit level (42 kA) with total selectivity

• H2: high short-circuit level (50 kA) with high selectivity (42 kA)

• H3: very high short-circuit level (66 kA) with very high selectivity (50 kA)

• L1: extremely high short-circuit level (150 kA) with strong current limitation and selectivity (10 kA)

Circuit breakers are fitted with a MicroLogic X control unit.

For full information about available circuit breaker models, interrupting ratings, sensor ratings, and control units, refer to LVPED216026EN MasterPacT MTZ with MicroLogic X Control Unit - Catalog.

Switch-Disconnectors

The switch-disconnector functions in the HA performance level (Icw = 36 kA/1s).

For information about available switch-disconnector models, refer to LVPED216026EN MasterPacT MTZ with MicroLogic X Control Unit - Catalog.

Neutral Position on 4P Devices

On 4P devices, the neutral is on the left side as standard. A right side neutral version is not available for circuit breakers.

For switch-disconnectors, the user can change the neutral position to the right side.

A labelling kit is provided with the switch-disconnector.
