General Electric Spectra RMS Molded Case Circuit Breaker – Product Spotlight

General Electric’s Spectra RMS Molded Case Circuit Breakers have a digital, solid state, RMS sensing trip system with field installable, front-mounted rating plugs to establish or change the breaker ampere rating.

Advanced models feature the microEntelliGuard Trip Unit, the newest and most advanced trip unit available in the Spectra line. The microEntelliGuard platform allows users to select the enhanced system protection, coordination, metering and communications options required for the most demanding applications.

Spectra series circuit breakers are available in four frame sizes rated up to 1200A:

  • SE150 frame, 15-150A
  • SF250 frame, 70-250A
  • SG600 frame, 125-600A
  • SK1200 frame, 200-1200A

Breakers options include 2 or 3 poles, with 240/480/600 VAC ratings. Interrupt ratings cover a wide range up to 100 kAIC at 480 VAC.

The trip unit uses digital sampling to determine the RMS value of sinusoidal and non-sinusoidal currents to accurately determine current values.

The solid state trip system includes several built-in benefits. This includes accurate sensing, insensitivity to ambient signals, support for communication and power management applications and additional support for protective relays.

SG600 and SK1200 models include the microEntelliGuard Trip Unit platform, which features adjustable Long-Time, Short-Time, Ground Fault and Ground Fault Alarm settings for enhanced time-current curve adjustability.

It also offers options for:

  • Basic and advanced metering
  • Protective relay options
  • Neutral protection
  • Waveform capture
  • Zone Selective Interlock
  • Modbus communications
  • and much more!
