Electronic Circuit Breakers (ECBs)

A high switch-on capacity is combined with an electronic relay.
WAGO’s space-saving ECBs come into play when the focus is on both safety and a superior price–performance ratio.

WAGO’s ECBs have a lot to offer:

  • They reliably protect against overload and short circuits.
  • They also enable the activation of high-capacitance loads of 50,000 μF and more, without increasing the rated current setting.
  • One-, two-, four- and eight-channel models and current ratings of 0.5 to 12 A offer you the flexibility you need for setting the rated current to suit your individual application.
  • With a maximum width of 45 mm (1.772 inches), these ECBs feature high channel density to save space in the control cabinet.
  • Some devices are also available with active current limitation, preventing the power supply unit from overloading during a short circuit.

Protect Small Currents Easily

New WAGO 0.5 A Electronic Circuit Breaker

With WAGO’s single-channel circuit breaker (787-2861/050-000), even small load currents of 0.5 A can now be easily protected in control circuits. Quick, reliable tripping after 4 ms is guaranteed with all seven available circuit breakers. In addition, the circuit breaker saves space in the control cabinet or system distribution box with its overall width of just 6 mm. Different control options for the integrated digital input allow channels to be set to a specific state, increasing usability. The digital output reports the current status. Since they have the same profile, direct commoning of the input and output voltages is possible across 857 and 2857 Series devices.

The Benefits for You:

  • Protection of load currents from 0.5 A to 8 A
  • Slim 6 mm (0.236 inch) housing saves space
  • Reliable tripping of the circuit breaker after just 4 ms
