Product Description
Molded Case Circuit Breaker 400AMP MCCB 3 Pole
Keyword:1P,3P(3P+N),4Pole, Apply for isolator switch, Electric and thermal magnetic tripping device,
Provide miniature circuit breaker lockouts,Similar Tmax.
Application of (SM8max) MCCB
The SM8max T1 1p, T1, T2, T3, Ts3, T4, T5 and T6 circuit breakers can be fitted 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 fixed threshold
forT1 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 fixed threshold for T1, T2, T3, Ts3
and T4 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 with protection 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 phase setting is required.
Working conditions of MCCB
1. Not over altitude 2000m;
2. Ambient temperature is between-25°C and +40°C ; Working in the medium which not any explosive,
not enough dielectric to corrode metal, no gas to damage insulation and electric conduction dust;
3. Working in the place would not be invaded by rain and snow; 3. Pollution degree3; 4. Mounting type.
Classification of MCCB
1) According to using: distribution circuit protection type, motor production type;
2) According to connection mode: front panel connection, back panel connection, plug-in connection;
3) According to operating way: for direct handle operating, for motor operator operating, for rotary handle operating.
4) According to the number of pole: 3,4 pole.
5) According to the accessory: with accessory setting, and without accessory setting.
