Reset after overload or short circuit disconnection

- remedy the external overload or

short circuit failure

- manual RESET on the breaker via

ON/OFF switch

- no reset with voltage interruptions

(status memory)

- no reset possible via external control

input IN

- external reset optionally possible via

reset input RE

Free-wheeling circuit

external free-wheeling diode

recommended with inductive load

Load outputs must not be connected in parallel

Status output SF

ESS22-TA-0x1

Electrical data

potential-free signal contact

1 break contact, terminal 11-12

(closed in OFF or failure condition)

1 make contact, terminal 13-14

(open in OFF or failure condition)

max. DC 30 V / 0.5 A, min. 10 V / 10 mA

Fault

signal output fault conditions:

- ON/OFF switch is in OFF position (manually)

- after overload/short circuit disconnection

- external control input (OFF)

- low voltage

Control input IN+/IN-

ESS22-TA-01x / ESS22-TA-03x

Electrical data

control input (IN+/IN-) is physically isolated

from load circuit (optocoupler)

voltage max. + DC 32 V

high > DC 12 V ≤ DC 32 V (switch on)

low ≤ DC 5 V > 0 V (switch off)

current consumption typically 3…9 mA

(DC +12 V…32 V)

Reset function

ESS22-TA-03x

A non-conducting load output (after an

overload/short circuit disconnection) can

be reset externally via the control input. In

order to do that the control input has to be

switched off for >100 ms

Links

manual ON/OFF switch on breaker is linked

to the external control input IN+ by means

of an AND function

Reset input RE+ / RE-

ESS22-TA-02x

Electrical data

reset input (RE+ / RE-) physically isolated

from load circuit (optocoupler)

voltage: max. + DC 32 V

high > DC 12 V ≤ DC 32 V

low ≤ DC 5 V > 0 V

power consumption typically 3…9 mA

(DC +12 V…32 V)

min. pulse duration for RESET 100 ms

Reset signal RE

The electronically blocked load output

(blocked after overload/short circuit

disconnection) may be reset via an external

reset pulse (+ DC 24 V).

A common reset signal can be applied to

several devices simultaneously.

RESET - pulse/edge from low (min. 100 ms)

to high (min. 100 ms)

Attention: when mounted side-by-side without convection the ESS22-T should not carry

more than 80 % of its rated load with 100 % ON duty due to thermal effects.
