Solutions for your safety

Type: ESS30-S


The electronic circuit breaker type ESS30-S has particularly been designed for decentralised and centralised 24V DC power supply units. Its very low quiescent current lays the foundation of the new protection category "Low Energy Breaker”. The combination of innovative electronic circuitry and well-proven physical isolation makes up a circuit breaker meeting all requirements of the DIN EN60934 (circuit breaker for equipment protection) and UL1077 (Supplementary Protector). This compact and pluggable type fits into the standard E-T-A terminal block systems (17plus, 18plus and SVSxxx power distribution systems).
