General Description
The CAMTEC ES 303 is the 3rd generation and cost-effective inrush current limiter. The limiter is designed for 200-240V
and can be operated in a 3x400Vac 16A networks with a neutral conductor. The ES 303 can either be used as 3-channel
single-phase ES or as a 3x400Vac ES . Each phase connection allows to connect 6000uF capacitive load. It is necessary
to connect the Neutral conductor to the ES to let the device operate. The PE conductor must not be connected to the
ES 303. The line frequency range is 16⅓Hz – 440Hz. The ES 303-Limiter shall be located between the line-
switcher/contactor and the load. The ES -models are designed for capacitive loads (not for inductive loads like
coils/transformers, not for AC-motors and not for DC-voltage application). In the moment of switching-on the system
the inrush current of the installed load will be limited for the defined time Ton . Independent from the previous inrush
level; the current limiting is always strict. After Ton elapses the current limiting circuit of the ES 303 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 Toff, it will be detected by the ES 303. As soon as the AC
recovers the inrush will be limited, again. The ES 303-models provide an internal temperature control. In case of a
failure the device shuts down to safely prevent from overheating or fire. The power consumption of the unit is <3,3W
(<3x1,1W per phase conductor at 230Vac)

The figures 1-1A, 1-1 and 1-1C show all
possible installation variations where
the ES 303 can be used. The neutral
must be connected to the unit. If the
neutral is not connected the ES 303
remains in the limiting mode. If so, the
device will overheat, and the internal
temperature protection will irreversible
blow. The device is powered between
phase conductor and the neutral. Each
phase connection is limited separately
thus a loss or a breakdown of each line is
protected by the ES 303 unit.
The figure 1-1 shows the distribution of
the potentials in relation to the neutral
connection. In three-phase systems, the
effective value of the sinusoidal AC
mains voltage between an outer
conductor and the neutral conductor is
230V, and between two outer
conductors is approx. 400V.
The ES 303 cannot be used in 3-phase
systems without an N-wire. For such
application we recommend the use of
our ES 00163 and ES 00323 inrush
limiters.

Field Applications
The ES 303 limiter allows connecting much more capacitive loads (e.g. LED-power supply / LED-driver) to a pre-installed
circuit breaker C . The ES avoids that the MC will be tripped. This occurs independent to the objective initial current.
The result is that the number of A.C. branch lines and the pre-installed MC 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 ES 303 is installed correctly,
the neutral wire (N) is looped trough. The inrush protection circuit always acts to the line conductor. The load relates
to 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. The ES 303 is designed for capacitive loads, only. The ES 303 cannot be
used together with transformers, coils, AC-motors & drives, heaters or with DC-voltage at all.
General type information ES 303.LED
The ES 303-model is a universal inrush current limiter. The concept design is made to construct optimized A.C.
networks in the building automation, the machine building 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 switch mode
power supply or a LED-driver. 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. Note that the ES 303 is not designed to operate together with gas induction lamps or other conventional
lighting device. The ES 303 is designed for capacitive loads, only.
Design-In of the ES 303 into A/C networks
The ES 303 model is a 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 C . All-dominant is the magnetic
trigger current. y using the empirical formula I(peak) x 0,707(factor) = I(r.m.s.) the tripping current can be defined exact. ear
in mind that all the higher the inrush current is, all the faster the input capacitor of several connected switch mode
power supplies will be loaded. Deduced by this fact we can say that within a 230V or a 400V 16A A/C N-wire network
the ES 303.LED.200/400V limiter is the right selection for a 13A 10kA or a 16A MC 10kA. The technical table on
page 2 shows the R.M.S value of the ES 303. Do not use an MC that has a larger value than 16A
(Fig.5 limiting time Ton) (Fig.7 inrush without ES 303)
(Fig.6 AC dump detection Toff) (Fig.8 inrush with ES 303)

Fig.7 and Fig.8
Fig.7 and Fig.8 show the typical start
behavior of a NTC protected switch
mode power supply. The used test
item is a CAMTEC HSE10001.24T
power supply with an output of
24V/42A (1008W) on DIN-Rail.
The peak current recordings show the
precise limiting of the inrush from
formerly 62Apeak to 16Apeak. The
corresponding R.M.S level, that is
responsible for the magnetic tripping
of the MC , is mark down by factor
0,707. After the time Ton elapsed it is
identified that the power supply
starts neatly into the continuous
operation mode. Now the current is
absorbed pulse-shaped from the AC.

consumption level of the HSE10001
hits 9A @ 230Vac.

Mounting Instructions
Follow the mounting restrictions to allow maximum lifetime of the product and to prevent from tripping the internal
temperature protection fuse. The ES 303 is an active device. The distance between an ES 303 and the next active or
temperature sensitive device shall be 17,5mm. To a non-active device, the distance can be 0mm. The power
consumption of the device is 3.3W (3x1.1W per phase conductor) constant at 230Vac continuous operation. Make
sure that the ventilation holes below and above the unit are not blocked to allow free air convection. The neutral
must be connected to the device. If the neutral is not connected the ES 303 remains in the limiting mode. If so, the
device will overheat, and the internal temperature protection will irreversible blow.
