M8max Series moulded case circuit breaker Application

The M8max T1 1p, T1, T2, T3, Ts3, T4, T5 and T6 circuit breakers can be fi tted with thermal magnetictrip 

units and are used in protection of alternating and direct current networks with a range of use from15 A 

to 800 A. They allow the protection against overload with a thermal device (with fi xed threshold for

T1 1p, T1, T2, T3, Ts3, T4 and adjustable threshold for T4, T5 and T6) realized using the bimetal 

technique and protection against short-circuit with a magnetic device (with fi xed threshold for T1, 

T2, T3, Ts3 andT4 up to 50 A and adjustable threshold for T4, T5 and T6).

The four-pole circuit breakers are always supplied with the neutral protected by 

the trip unit and withprotection of the neutral at 100% of the phase settings up to 100 A. 

For higher settings, the protection of the neutral is at 50% of the phase setting unless 

the protection of the neutral at 100% of the phasesetting is required.
