General Description:

The CAMTEC ESB101-series are the 2nd generation and cost effective inrush current limiters. The limiters are made for
115/230Vac 16A networks. The line frequency range is 16⅓Hz – 440Hz. The ESB101-Limiter shall be located between the
line-switcher/contactor and the load (p.2/Fig.1). The ESB-models are designed for inductive and capacitive loads. In the
moment of switching-on the system the inrush current of the installed load will be limited for the defined time T
(p.4/Fig.5). Independent from the previous inrush level; the current limiting is always strict. After Ton elapses the current
limiting circuit of the ESB101 will be bypassed. Then the load is directly connected to the AC. The electrical network can
be stressed with current loads as normal (e.g. motors, pumps). If an AC dump overshoots the defined time T
detected by the ESB101 (p.4/Fig.6). As soon as the AC recovers the inrush will be limited, again (p.2/Fig.3 & 4). The
ESB101-models provide an internal temperature control. In case of a failure the device shuts down to safely prevent
from overheating or burning.

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.

The ESB101 models are the precise inrush current limiter with an overall tolerance of ±6% of the face value. For the
dimension of an upstream connected circuit breaker the R.M.S is the key value of the inrush current, not the peak
current. The thermal trigger point will not be met, even while using an extreme fast CB. All-dominant is the magnetic
trigger current. By using the empirical formula I
Bear in mind that all the higher the inrush current is, all the faster the input capacitor of a number of connected switch
mode power supplies will be loaded. Deduced by this fact we can say that within a 230V 16A A.C. network not the
ESB101.16 limiter is the right selection for a CB B16A, but the ESB101.LED.230Vac. The technical table on page 2 shows
the R.M.S value of all the ESB101 types and models.
