Electronic circuit protector type ESX10 is designed to ensure selective

disconnection of DC 24 V load systems.

DC 24 V power supplies, which are widely used in industry today, will

shut down the output in the event of an overload with the result that

one faulty load in the system can lead to complete disconnection of

all loads. As well as an unidentified failure this also means stoppage

of the whole system.

Through selective disconnection the ESX10 responds much faster

to overload or short circuit conditions than the switch-mode power

supply. This is achieved by active current limitation. The ESX10 limits

the highest possible current to values between 1.3 to 1.8 times the

selected rated current of the circuit protector. Thus it is possible to

switch on capacitive loads of up to 20,000 μF lamp loads, but they

are disconnected only in the event of an overload or short circuit.

For optimal alignment with the characteristics of the application the

current rating of the ESX10 can be selected in fixed values from

0.5 A...12 A. Failure and status indication are provided by a multicolour

LED and an integral short-circuit-proof status output or a potential-free

signal contact.

The ESX10, with a width of only 12.5 mm, can be plugged into the

E-T-A power distribution socket Module 17plus ensuring ease of

installation and saving space in control cabinets.

Upon detection of overload or short circuit in the load circuit, the

MOSFET of the load output will be blocked to interrupt the

current flow. The MOSFET and the load circuit may be re-activated

via the remote electronic reset input or manually by means of the

ON/OFF button. When starting up the system, the load circuit may

also be manually disconnected.

Description

Features

Approvals

The user should ensure that the cable cross sections of the relevant

load circuit are suitable for the current rating of the ESX10 used.

Automatic start-up of machinery after shut down must be prevented

(Machinery Directive 98/37/EG and EN 60204-1). In the event of

a short circuit or overload the load circuit will be disconnected

electronically by the ESX10.

Selective load protection, electronic trip characteristics.

Active current limitation for safe connection of capacitive loads

up to 20,000 μF and on overload/short circuit.

Current ratings 0.5 A...12 A.

Reliable overload disconnection with 1.1 x I

load lines or small cable cross sections (see table 3).

Manual ON/OFF button (S1).

Control input IN+ for remote ON/OFF signal (option).

Clear status and failure indication through LED, status output SF

or Si contact F.

Electronic reset input RE (option).

Integral fail-safe element.

Width per unit only 12.5 mm.
