Description
ESS30-S... The electronic circuit breaker ESS30-S with physical isolation is the globally unique electronic overcurrent protection for DC 24 V applications as a “low energy breaker”. For the use in decentralised and centralised power supply units, it meets the requirements to DIN EN 60934, to UL1077 as a Supplementary Protector and to UL 1310 as “Class2 power unit” (NEC class2). The compact device can be plugged into the terminal blocks 17plus and 18plus and into the SVS power distribution systems and ensures quick and easy installation. The ESS30-S is only 12.5 mm wide and selectively protects all DC 24 V load circuits. This is achieved by a combination of active electronic current limitation in the event of a short circuit and overload disconnection at typically 1.2 times rated current. DC 24 V switch-mode power supplies are widely used in automation today. In the event of an overload, however, they turn down the output voltage which is intended to power all connected loads. So if there is a failure in a single load of the system, the supply voltage will break down also in all other load circuits. Not only does this frequently cause undefined fault conditions, but it can even lead to machine stoppages or system downtimes. The max. possible overcurrent is limited to typically 1.2 times rated current (see table 1). Switching capacitive loads up to 40,000 µF is possible without any problems. For adjustment to the load conditions the current rating can be selected in fixed values from 0.5 A to 10A and adjustable versions 1A/2A or 3A/6A are also available. Visual status indication is by means of a multicoloured LED and by integral signal outputs. The manual ON/OFF switch on the device itself allows start-up of certain individual load circuits and reset after disconnection on grounds of overcurrent.

Application note l The user has to ensure that the cable cross section of the load circuit in question complies with the current rating of the ESS31-T used. l In addition special precautions must be taken in the system or machine (e.g. use of a safety PLC) which reliably prevent an automatic re-start of parts of the system (cf. Machinery Directive 2006/42/EG and EN 60204-1, Safety of Machinery). In the event of a failure (short circuit/overload) the load circuit will be discon- nected electronically with physical isolation of the contacts by the ESS31-T.

Electronic circuit breaker ESS30-Sxxx-DC24VElectronic circuit breaker ESS30-Sxxx-DC24V www.e-t-a.de 2044 Typical time/current characteristic (Tamb = 25 °C) trip time depends on rated current (see table 1) IK 10000 1000 1 2 4 trip time in seconds ...times rated current 100 0,5 0,1 0,01 3 5 max. 1.35 x IN disconnection and current limitation typically 1.2 x IN min. 1.05 x IN l The overload trip time is typically 500 ms l The electronic current limitation typically begins at 1.2 x IN (exception: ESS30-S-…-3.6 A CL2 typically 1.05 x I N). This means: under all overload conditions (independent of power supply and load circuit resistance) typically 1.2 times rated current is applied until disconnection. The corresponding current limitation value ILimit depends on the current rating of the device IN. l Without the current limitation getting into effect at typically 1.2 x IN there would be a much higher overcurrent in the event of an overload or short circuit. l Reset of the circuit breaker is only possible approximately 10 sec after tripping.
