Electronic Circuit Breakers

Electronic circuit breakers (ECBs) are advanced electrical safety devices built to protect electrical circuits from damage caused by electrical overloads, short circuits, or other electrical faults. These specialised components use solid-state technology that interrupts the current flow upon detection of faults. Unlike traditional mechanical circuit breakers, electronic circuit breakers use electronic components to detect and rapidly respond to electrical anomalies, providing faster, reliable, and more precise protection. A typical electronic circuit breaker comes equipped with key elements, including sensors, microcontrollers, and communication interfaces for optimised operation in various settings. 

Benefits of Using Electronic Circuit Breakers Over Mechanical Circuit Breakers

Using an electronic circuit breaker offers unprecedented benefits in terms of:

  • Enhanced Precision
  • Faster Response Time 
  • Programmable Settings
  • Compact Design 
  • Increased Protection
  • Reduced Downtime
  • Lower Maintenance Costs 
  • Improved Energy Efficiency 
  • Enhanced Safety.

Common Types of Electronic Circuit Breakers

ECBs come in various types, including: 

  • Solid-State Circuit Breakers – A solid-state circuit breaker is the common type that detects and interrupts fault currents using electronic components. These circuit breakers provide rapid response times and precise control in various applications.
  • Hybrid Circuit Breakers – These devices combine mechanical and electronic elements to improve performance and longevity. A hybrid circuit breaker offers enhanced protection and efficiency in modern electrical systems.
  • Digital Circuit Breakers – Digital circuit breakers use microprocessors to monitor and manage electrical circuits, enabling advanced features like remote monitoring and control. They provide superior diagnostic capabilities and are often used in smart grid applications.
  • Programmable Circuit Breakers – These circuit breakers allow users to set custom trip parameters and protection settings, offering flexibility for diverse electrical environments. They are perfect for complex systems that require tailored protection solutions.    

Typical Applications of Electronic Circuit Breakers

ECBs integrate electronic components designed to cut off the current when excess current is detected automatically. They are indispensable components in various applications where electrical protection is required, such as:

  • Residential and Commercial Buildings
  • Industrial Applications
  • Data Centers
  • Renewable Energy Systems
  • Automotive Industry
  • Marine Applications
  • Telecommunication Systems
  • Medical Equipment.

ESX10-TB101-DC24V 10A, ETA

ESX10-TB101-DC24V 10A, ETA

ESX10-T Electronic Circuit Protectors Electronic circuit protector type ESX10-T is designed to ensure selective disconnection of DC24V load systems. By active current limitation, ESX10-T responds much faster to overload or short circuit conditions than switch-mode power supply. The ESX10-T limits the highest possible current to 1.3 to 1.8 times the selected rated current of the circuit protector. It is therefore possible to switch on capacitive loads of up to 20,000μF, but they are disconnected only in the event of an overload or short circuit. Selective load protection, electronic trip characteristics Reliable overload disconnection with 1.1 x l N plus, even with long load lines or small cable cross sections Manual ON/OFF button (S1) Status and failure indication through LED, status output SF or Si contact F Integral fail-safe element adjusted to current rating Can be snapped onto symmetrical rails for ease of installation and space-saving in control cabinets Ease of wiring through busbar LINE+ and 0 V as well as signal bars and bridges Approvals UL, CSA Approvals UL, CSA

2CDE601101R2010 EPD24-TB-101-10A, ABB

EPD24 Series Electronic Protection Device ABB EPD24 series electronic protection devices offer overcurrent protection for 24 V dc load circuits. This protection is achieved by a combination of active electronic current limitations. In the case of a short circuit and an overload, deactivation from 1.1 x Input occurs. If a fault occurs in a load circuit, the EPD24 protection device will detect this rapidly and reliably, disable the power output transistor, interrupting the current flow in the defective circuit. The maximum possible overcurrent is always limited to 1.3…1.8 times the selected rated current. An activation of capacitive loads up to 20,000 μF is possible, deactivation only occurring in the case of overloads or short circuits. Selective load protection Reliable overload disconnection with 1.1 x Input plus Manual ON/OFF button Clear status and failure indication through LED and integrated auxiliary contact Integral fail-safe element adjusted to current rating Width per unit only 12.5 mm DIN rail mounting Easy wiring through busbar LINE+ and 0 V as well as signal bars
