Technical Parameters of Schneider Molded Case Circuit Breakers
Classification of Schneider Molded Case Circuit Breakers
1. By installation method: vertical installation, horizontal installation.
2. By purpose of circuit breaker: distribution protection type, motor protection type.
3. By wiring method: front panel wiring, rear panel wiring, plug-in wiring.
4. By operation method: direct handle operation, external rotary handle operation, electric operation.
5. By trip unit type: instantaneous trip only (magnetic trip), thermal-magnetic trip (compound), electronic trip.
6. By number of poles: two-pole, three-pole, four-pole; in four-pole circuit breakers, there are four types of neutral pole (N pole):
Type A: N pole without overcurrent trip, and N pole is always closed, not switching with the other three poles.
Type B: N pole without overcurrent trip, and N pole switches with the other three poles.
Type C: N pole with overcurrent trip, and N pole switches with the other three poles.
Type D: N pole with overcurrent trip, and N pole is always closed, not switching with the other three poles.
