WAGO Electronic Circuit Breakers (ECBs) with a high switch-on capacity is combined with an electronic relay.

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.

WAGOs full line of Single and Multi-Channel ECBs have a lot to offer:

  • They offer reliable protection against overload and short circuit.
  • They also enable activation of high-capacity loads of 50,000 microfarads and higher – without the need to increase the nominal current setting.
  • 1-, 2-, 4- and 8-channel models with 0.5 to 16A current ratings offer you the flexibility you need for setting the nominal current to suit your individual application.
  • Single Channel ECBs 6mm wide and Multi-Channel ECBs starting at 32mm wide allow for high channel density in a small space.
  • Some devices are also available with active current limitation, preventing the power supply unit from overloading during a short circuit.

New Product Feature

787-3861: Next Generation WAGO Single-Channel Electronic Circuit Breakers

WAGOs next generation 24 VDC, 1-channel ECBs improve operations and offer a significant cost savings for customers. The 787-3861 family of products no longer has a hard to open cover to access the manual reset wheel, instead offering an indented button to be operated with a tool. The devices include LED status indicators to identify device status as well as S1 input and S2 output to monitor and control the device remotely. New in the 787-3861 family is the ability to configure the S2 output on ALL variants in to report 7 different states including triggered or manually switched off, and early load warnings. On adjustable units, the current limit is able to be set via discrete setting wheel instead of a sequence of inputs through the manual input wheel, making it much easier to set and identify current setting when first glancing at the device. In addition, 4 A and below variants now include NEC Class 2 output options as well as a new 0.5 A to 4 A configurable NEC Class 2 version.

Advantages:

  • 24 VDC; six fixed and two adjustable rated current versions from 0.5 A to 8 A
  • Easy to identify current setting on adjustable versions
  • 6mm slimline design
  • Easy Jumpering to 857 and 2857 series devices with same terminal layout
  • High switching capacity: > 50,000 μF for non-NEC Class 2 devices
  • S1 Input and Configurable S2 Output for easy remote monitoring and control
  • Approvals: CE, UL 61010, UL 2367, and UL 1310 NEC Class 2 Versions
