Electronic Circuit Protectors

E-T-A ESX10-series of circuit protectors extend their our product group of electronic overcurrent protection devices for DC 24 V applications.

Correct protection of loads supplied by switch mode power supplies holds certain challenges. Switch mode power supplies are limited in power and in the event of a failure, they can only supply limited currend. A conventional MCB requires a multiple of its own current rating to ensure timely trip in the event of a failure. This makes the use in standard protection solutions provided by MCBs problematic. Switch mode power supplies often are not able to supply the required trip current in the event of a failure.

Benefits of E-T-A Electronics Circuit Protectors

• Increases machine uptime through clear failure detection and stable power supply
• Simplifies planning through clear sizes and ratings
• Saves costs and time through fast and flexible mounting including integral power distribution

For many applications, single or group signalling of the protection devices is a must so as to ensure uninterrupted monitoring of the protected load circuits. The ESX10 portfolio offers a range of signalling and alerting options.These include conventional, potentialfree break contacts, make contacts and change-over contacts or also pure status outputs in standard or negative version. For all requirements, the ESX portfolio holds the suitable product version. In addition, there are remotely controllable versions available with reset function in the event of a failure and with complete controllability.
