Electronic Circuit Breakers (ECBs)

ECBs are the space-saving and precise solution for reliable protection of DC circuits. Thanks to the comprehensive range of approvals, they can be used in a wide variety of ways and can also be controlled and monitored remotely via the communication interface. Our circuit breakers are the perfect addition to your power supply system and they are also maintenance-free.

The Benefits of WAGO’s ECBs for You

Discover Our Electronic Circuit Breakers (ECBs)

Single-Channel ECBs

With a width of only 6 mm (0.236 inch), these new circuit breakers are the narrowest ECBs currently on the market. They are approximately 66% smaller than miniature circuit breakers to save even more space, particularly when used in control cabinets. These ECBs enable high-capacity loads greater than 50,000 microfarads to be switched on, without requiring further action or changing the nominal current, helping reduce false tripping due to inrush currents.

Your benefits:

  • 24 VDC / in six versions for rated currents of 1 to 8 A
  • With devices color coded according to nominal current
  • An extremely slimline version
  • Switch-on capacity: >50,000 µF
  • Wide operating 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 combined as a group signal for up to 30 devices
  • Approvals: CE, UL 61010, UL 2367

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

WAGO’s space-saving, multi-channel ECBs offer reliable protection with an excellent price-performance ratio. These circuit breakers are highly configurable and provide dependable protection against overload and short circuits. With a compact 32 mm (1.26 inch) housing width for 4- or 8-channel versions, they offer high channel density and save space in the control cabinet. Digital inputs and outputs enable centralized status queries, as well as remote switching and resetting of all channels.

Key Benefits:

  • 2-, 4-, or 8-channel circuit breakers with channel-specific tripping current selection from 0.5 to 16 A
  • Reliable tripping behavior, even with small conductor cross-sections
  • Versions with active current limiting and NEC Class 2 approval
  • Space-saving: only 32 mm (1.26 inch) housing width for 4 or 8 channels
  • Collective signaling and remote control of all channels
  • Broad range of applications thanks to multiple approvals (CE, UKCA, UL 60950, UL 2367, DNV)

The New Generation of Intelligent ECBs

Communication for Total Control and Compact Protection

The latest expansion of the Electronic Circuit Breaker (ECB) portfolio introduces advanced communication interfaces for IO-Link, Modbus RTU, and the Manchester protocol. These new interfaces significantly enhance the functionality of the circuit breakers by enabling detailed, channel-specific monitoring and control via connected controllers. Each circuit breaker becomes an intelligent device capable of transmitting precise current and voltage data for every channel. This information supports real-time monitoring, fault diagnostics, and predictive maintenance. In the event of a trip, remote response capabilities enable immediate action, minimizing system downtime.

Key Benefits:

  • High-precision protection in compact spaces
  • 4- or 8-channel circuit breakers with selectable tripping currents per channel (1 to 16 A)
  • Bidirectional communication via IO-Link, Modbus RTU, or Manchester protocol
  • Full remote access for status monitoring and individual channel operation
  • Fully configurable — locally or remotely
