The ESS30-S electronic circuit breaker from E-T-A Circuit Breakers provides overcurrent protection for DC 24 V applications, designed for both decentralized and centralized power supply units. It features a compact design, measuring only 12.5 mm in width, and can be easily plugged into E-T-A's 17plus and 18plus terminal blocks as well as SVS power distribution systems. The device offers fixed current ratings ranging from 0.5 A to 10 A, with adjustable options available for 1 A/2 A and 3 A/6 A configurations. This circuit breaker employs active electronic current limitation to manage overloads, disconnecting at typically 1.2 times the rated current, which helps prevent system downtimes caused by voltage drops in switch-mode power supplies. It can handle capacitive loads up to 40,000 µF and includes visual status indicators via a multicolored LED, along with integral signal outputs for enhanced monitoring. The ESS30-S is compliant with various standards, including UL1077 and UL1310 for Class 2 power units, ensuring its reliability in safety-critical applications.
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.
