Field Applications:
The ESB101 limiter allows connecting much more loads (e.g. LED-power supply / LED-driver) to a pre-installed circuit
breaker CB (Fig.2). The ESB definitely avoids that the CB can be tripped. This occurs independent from the objective
initial current. The result is that the number of A.C. branch lines and the pre-installed CB can be reduced dramatically.
Installation cost exhibit a sustained decline.
Alternatively the cross section of the branch lines can be reduced when using smaller and faster responding circuit
breakers. The cost saving from copper is essential. Sensitive AC networks can be fused safer (e.g. Traffic Control Systems,
Street-Lighting, Parking Lots and Tunnels)
When the ESB101 is installed correctly, the neutral wire (N) is looped trough (Fig.1). The inrush protection circuit always
acts to the line conductor. The load is connected with the AC in such a way that a circuit breaker or an earth-leakage-trip
works within the limits of the legal rules. This fact is also applied while the limiting circuit acts.
Special Models ESB101.LED with 115Vac or 230Vac
Compared to all other ESB101-models the LED-types are the universal inrush current limiters. The concept design is
made to construct optimized A.C. networks in the building automation and in the lighting sector. Tripping the installed
circuit breaker will be effectively prevented. The inrush limiting time is adjusted to the values of a typical LED power
supply or LED-drivers. The connectable load capacity is such as high, that even in the extremes cases it is rather
impossible to exceed it in a 16A network. Installed contractors will be discharged and their lifetimes will considerable
increase. As well, the ESB101 LED-models are made to support the conventional lighting technology. The operation of an
ESB101 with an electronic ballast leads to the same repeatable results. To protect the installed relay in a controlled
DALI-/DMX-Multiplexer we advise to use the ESB101.23 for a 16A relay or the ESB101.16 for a smaller relay.
