Lovato 11SM1B08 motor protection circuit breaker that is adjustable from 0.25 to 0.40 AMPS, has a on/off toggle switch and mounts on standard 35MM din rail. This motor protector has a Class 10 tripping characteristic, is phase failure sensitive (trips in a phase loss condition) and lasts for 100,000 electrical and mechanical operations. Front and side mounted auxiliaries can be added to the 11SM1B08 for motor signalling and tripping purposes.
| AMP range | 0.25 to 0.40 AMPS |
| Phase loss protection? | Yes |
| Trip Class | 10 (trips in 10 seconds or less) |
| Reset | Manual |
General characteristics
The SM1B series is a new generation of manual starters with thermal and magnetic trip releases. Motor control and protection, up to 20HP at 460V, are possible by the choice of suitable adjustment range, 0.1 to 32A. A magnetic trip indicator integrated on the SM1B starters avoids dangerous closing operations during short-circuit conditions, previously disconnected by the starter. The SM1B types are suitable for isolation.
