General Description:
The CAMTEC ESB-series are the 2nd generation and cost effective inrush current limiters. The limiters are made for
200/400/500Vac 16A networks. The line frequency is 50/60Hz. The ESB-Limiter shall be located between the line-
switcher/contactor and the load. 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
on
. Independent
from the previous inrush level; the current limiting is always strict. After T
on
elapses the current limiting circuit of the ESB
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
off
, it will be detected by the ESB. As soon
as the AC recovers the inrush will be limited, again. The ESB-models provide an internal temperature control. In case of a
failure the device shuts down to safely prevent from overheating or burning.

(Subject to alterations. This product is not designed to be used in applications such as life support systems wherein a failure or malfunction could result in injury or death)
Field Applications:
The ESB limiter allows connecting much more loads (e.g. LED-power supply / LED-driver) to a pre-installed circuit breaker
CB. The ESB definitely avoids that the CB can be tripped. This occurs independently 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 ESB is installed correctly, the neutral wire ( ) 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.
Integrated Phase Control:
The 3-phase ESBs have an integrated phase control circuit with basic functions. Each phase is controlled separately.
Each phase is limited separately. The error signals are given for each phase an independent. This provides a connected
SPC access to display complex and interlinked failures in a major control room. The different signalized failures will be
described on page 4 of this manual.

Operation with SPC to safeguard AC-failures:
The signals "Phase-Error" and "Asymmetry-Error" can be used to trigger an external contactor. The installed load will be disconnected if an error occurs. As soon
as the error recovers the installed load will be reconnected to the AC.
(find attached pictures „Phase-Loss &-sequence“ and „Asymmetry, Over-/Low Voltage“. The contactor is always named K2.)
Phase Loss & Sequence
In case of phase loss relay 4 opens
after a delay time of 30ms. Synchro-
nistic the relay of the appropriate
phase opens, too and its green LED
extinguishes. When the phase
sequence is incorrect, relay 4 opens
after a delay time of 30ms.
The Phase
Error LED
lights red. When the phase
sequence is correct the LED is off and
the relay 4 is closed.
Asymmetry, Over
-
/Low Voltage
The asymmetry monitoring detects a
voltage difference of the three phases
to each other. This kind of measuring
enables work without the N line (four
wire system). If the voltage of the
measured AC line drops or exceeds
15% of its nominal selected input relay
8 opens 8-10s delayed and the
Asymmetry LED lights red. Measuring
tolerances are ±2%.
Phase Loss
Message Block
Relay 5 to 7
are galvanic insulated via
opto couplers. If L1 to L3 are
operating the relays are closed. If one
phase drops its relay opens and the
message can be used with an active
signal (60V/500mA maximum load
each relay).

Design-In of the ESB into A.C. etworks
The ESB 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
(peak)
x 0,707
(factor)
= I
(r.m.s.)
the tripping current can be defined fairly exact.
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. The technical table on page 2 shows the R.M.S value of all the ESB 3PH types and
models.
