Wago ECB's within the WAGO EPSITRON® Power Supply Lineup
Learn how Wago ECB's within the WAGO EPSITRON® Power Supply lineup provide greater system safety and compare protection systems.
Wago 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. ECBs from the EPSITRON® family 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 microfarad and higher – without having to increase the nominal current setting.
- One, two-, four- and eight-channel models with 0.5 to 12 A current ratings offer you the flexibility you need for setting the nominal current to suit your individual applications.
- 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.

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.
Your benefits:
- 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
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
What Types of Fuse Protection Are There?
Thermal
Possible applications:
- Low-voltage, high-power and DP fuses
- High overcurrents required for fast tripping
Explanation:
- In the example: ten-fold overcurrent (related to fuse nominal current): tripping within the range 30 ms (best case) or 200 ms (worst case)
- Only two-fold overcurrent: tripping within the range 2 s (best case) or >100 s (worst case)
Thermal and Magnetic
Possible applications:
- Found in circuit breakers or motor protection switches
- High overcurrents required for fast tripping
Explanation:
- In the example: three- to five-fold overcurrent for B-characteristic and AC operation, additional safety factor 1.2 or 1.5
- Thus, in the worst case scenario, a tripping current of 7.5 times the nominal current is necessary.
Electronic
Possible applications:
- Ensure precision settings
- Reaction within a short time – even at low overcurrents
- Protection of long cable runs and small cross sections
Explanation:
ECBs ensure reliable protection, even at low overcurrents and with long cable lengths.
