Double pole protection for ungrounded DC 24 V systems

The double pole electronic circuit breaker ESS22-T allows individual integration in ungrounded DC 24 V power supply systems. Major applications are IT systems in the steel industry, in process ontrol of the chemical industry as well as in power plant technology. The ESS22-T, with a width of only 22.5 mm and a height/depth of only 90 mm, can be snapped onto symmetrical rails, ensuring ease of installation and saving space in compact control cabinets.
Type ESS22-T provides selective disconnection and double pole physical isolation of loads and will only disconnect faulty load circuits in the event of an overload or short circuit. It responds fast enough to ensure stability of the 24 V control voltage for the other loads (PLCs, bus couplers, control systems
etc.), preventing stoppages of the entire automation system.

Features and benefits
● Compliance with requirements of new Machinery Directive 2006/42/EC and the affiliated standard EN60204-1 “Safety of Machinery, Electrical Equipment of
Machines”, para 9.4.3.1
● Stability of DC 24 V control voltage in the event of overload or short circuit
● Safe connection of capacitive loads up to 20,000 μF
● Physical isolation of the load circuit ensures complete disconnection of load
● Reliable disconnection even with high cable attenuation
