Motor protection circuit breaker, 100 kA SCCR, Class 10
Main circuit wiring uses spring-loaded terminals accepting 2× 0.5–2.5 mm² solid or stranded — no screw torque to check, just strip and insert.
Ratings and coordination
For backup fuse coordination, the breaker requires gL/gG fuses: 32 A at 400 V and 500 V, 25 A at 690 V. The 4 A rating at 480 V and 600 V and 0.33 hp at 230 V define the motor full-load current it protects. Maximum switching rate in AC-3 duty is 15 operations per hour — fine for normal starting duty, not for jogging or high-cycle applications.
