However, DC 24 V switch-mode power supplies, which are widely used in industry today, may stop entire plants as their self-protecting characteristics will shut down the output in the event of overload or short circuit currents with the result that one faulty load in the system can lead to complete disconnection of all loads.
The E-T-A Electronic Circuit Breaker ESS20 helps to overcome this problem and ensures selective disconnection with genuine physical isolation in the event of a fault (overload or short circuit) while allowing individual loads to start up.
The circuit breaker therefore meets important requirements of the European Machinery Directive 98/37/EC, of European standard EN60204-1 and for CE marking.
Electronic Circuit Protector - ESX10 prevents a DC 24 V power supply from being shut down inadvertently even with load lines with high attenuation.
In the event of a sustained fault condition it physically disconnects the faulty load circuit from the 24V supply.
Pure electronic disconnection of machinery fitted with a safety PLC to prevent dangerous machine operation in the event of a failure is provided by the E-T-A Electronic Circuit Protector ESX10: selectively and reliably.
Features and Benefits of Electronic Circuit Protector - ESX10
- Professional overcurrent protection prevents undefined fault conditions, stoppages and downtime
- Integration of tailor-made safety at the equipment design stage saves expensive retrofitting
- Standard-compliant components facilitate global installation of customers’ equipment (EN60204-1, CE certification, UL 1077)
- The use of pre-wired E-T-A power distribution systems reduces wiring and installation costs
