The Benefits of WAGO’s ECBs for You

Discover Our Electronic Circuit Breakers (ECBs)

1-Channel Electronic Circuit Breakers

With a width of just 6 mm (0.23 inch), our single-channel ECBs save a tremendous amount of space in the control cabinet and offer an excellent price-performance ratio, as well as fast and, above all, safe tripping. The digital signal input enables both remote switching and reset, and the individually configurable signal output allows the use of an ECB for various feedback messages on the operating status to the control level. In addition, switch higher capacitive loads and benefit from fewer false trips due to excessive inrush currents.

Your Benefits:

  • 24 VDC available with nominal currents from 0.5 to 8 A
  • Versions with permanently set or configurable trip current
  • Very slim 6 mm (0.23 inch) design
  • High switch-on capacities
  • Resetting and on/off switching directly on the module or remotely via digital input signal
  • Triggered signal output – can also be commoned as a group signal for up to 30 devices

2-, 4- and 8-Channel Electronic Circuit Breakers (ECBs)

WAGO's space-saving, multi-channel ECBs provide reliable protection at a very good price-performance ratio. They offer outstanding features and reliable protection against overload and short circuits. With a maximum width of 45 mm (1.772 inches), these ECBs feature high channel density to save space in the control cabinet.

Your Benefits:

  • 2-, 4- and 8-channel circuit breaker with currents adjustable from 0.5 to 12 A
  • High switch-on capacity: > 50,000 µF
  • Communication interface allows remote monitoring
  • Also available with active current limitation
  • Numerous approvals (CE, UKCA, UL 60950, UL 2367, DNV) allow a wide range of applications
