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.

Product Overview

Discover Our ECBs

Single-Channel Electronic Circuit Breakers (ECBs)

The new modules are just 6 mm (0.236 inch) wide, making them the slimmest ECBs currently available on the market. They are approximately 66 % smaller than miniature circuit breakers, saving even more space, particularly when used in control cabinets. These ECBs allow high-capacitance loads greater than 50,000 μF to be switched on – helping you reduce false tripping due to inrush currents.

The Benefits for You:

  • 24 VDC; six versions available for rated currents of 1 to 8 A
  • Devices color coded according to rated current
  • An extremely slimline design
  • Switch-on capacity: > 50,000 µF
  • Wide surrounding air temperature range: −25 … +70 °C (−13 … +158 °F)
  • Resetting, 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
  • Approvals: CE, UL 61010, UL 2367

2-, 4- and 8-Channel ECBs

WAGO’s space-saving ECBs provide reliable protection with a superior price–performance ratio. They offer both 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.

The Benefits for You:

  • Two-, four- and eight-channel protective switch with currents adjustable from 0.5 to 12 A
  • High switch-on capacity: > 50,000 µF
  • Communication capability: remote monitoring and reset
  • Optional active current limitation
  • Approvals: CE, UL 60950, UL 2367, GL
