Type ESS30-S

60 mm
Typ ESS30-S von E-T-A: mit galvanischer Trennung; einzigartige Elektronischer Überstromschutz für DC 24 V Anwendungen


The electronic circuit protector 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.

New! Now also adjustable versions available!
