General Description
The CAMTEC ESB303 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 ESB303 can either be used as 3-channel
single-phase ESB or as a 3x400Vac ESB. Each phase connection allows to connect 6000uF capacitive load. It is necessary
to connect the Neutral conductor to the ESB to let the device operate. The PE conductor must not be connected to the
ESB303. The line frequency range is 16⅓Hz – 440Hz. The ESB303-Limiter shall be located between the line-
switcher/contactor and the load. The ESB-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 T
on
. Independent from the previous inrush
level; the current limiting is always strict. After T
on
elapses the current limiting circuit of the ESB303 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 ESB303. As soon as the AC
recovers the inrush will be limited, again. The ESB303-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)
