Product Description
The Lovato SM1R1800 manual motor protector is adjustable from 13 to 18 AMPS, mounts on standard DIN rail and has screw terminals for easy installation. This motor protector/circuit breaker will trip in 10 seconds or less (trip class 10) in an over current condition, protects against phase loss with single phase sensitivity and has a 100,000 electrical and mechanical operational lifespan. For even more versatility, the Lovato SM1R1800 has optional front and side mount auxiliaries along with side mounted under voltage trips to accommodate any applications needs. For a higher rated SM1R, try the SM1R2300, which adjusts up to 23 AMPS and has the same dimensions and foot print in the series.
