15 - 1 200 A | Spectra® RMS GE Circuit Breakers

Spectra® RMS Molded Case Circuit Breakers (SE150, SF250, SG600 and SK1200) have a digital, solid state, RMS sensing trip system with field installable, front-mounted rating plugs to establish or change the breaker ampere rating. Adjustable instantaneous with tracking short-time is standard on all frames. The trip unit uses digital sampling to determine the RMS value of sinusoidal and non-sinusoidal currents.

Spectra® RMS Molded Case Circuit Breakers with MicroVersaTrip® Plus/PM Trip Units (SG600 and SK1200) add adjustable Long-Time, Short-Time, Ground Fault, metering (basic and advanced), trip indication, communications and protective relay options for enhanced system protection and power management capability.
