for DIN/VDE0603 cutout box

The ESB303 is a budget-priced inrush peak

current limiter for high loads in LED-

applications, complex automation systems

and in the machine building. The ESB303

offers effective and interference free operation

with capacitive loads. It is simple to integrate

into existing equipment. The ESB303 is self-

powering and does not require an external

power supply.

Made in Germany

Use ESB303 either as a

3-channel-230V-ESB or to

protect 400Vac networks.

No simple NTC-solution! It

allows to reduce cabling

sections and to install fast

circuit breakers.

100% protection from

tripping pre-installed

circuit breakers or burning

relay and line switch

contacts.

The neutral must be connected to the unit. If the neutral is not connected the ESB303 remains in the limiting mode. If so, the device will overheat, and the internal temperature protection will irreversible blow.

Field Applications The ESB303 limiter allows connecting much more capacitive loads (e.g. LED-power supply / LED-driver) to a pre-installed circuit breaker CB. The ESB avoids that the MCB 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 MCB can be reduced dramatically. Installation cost exhibit a sustained decline.

Mechanics IP20 housing, UL94V-0 ABS with RTI 85°C, housing for DIN/VDE0603 cutout box and wall mount. DIN 43880 with IEC standardized ventilation slots. Save fix on DIN-Rail TS35mm (7.5/15) DIN/EN60715. It is designed for building cabinets DIN/VDE0603. Easy to wall mount by multifunctional housing; remove the DIN-Rail latch and access the two mounting holes to screw the ESB303 to any flat surface.
