CBM E8 24DC/0.5-10A NO-R Electronic Circuit Breaker

Product Description

CBM E8 24DC/0.5-10A NO-R (Order No. 2905744) is an 8-channel 24VDC electronic device circuit breaker of Phoenix Contact CBM series, with independently adjustable rated current per channel and active current limiting protection. It adopts tool-free Push-in connection and 35mm DIN rail mounting. It protects 24V DC loads against overload and short circuit. Built-in intelligent current analysis distinguishes normal load, capacitive inrush current, overload and short circuit. Early warning is triggered when channel current exceeds 80% of set value. NO-R normally-open remote signal contact transmits fault status remotely. Electronic lock prevents accidental modification of current settings. Single channel fault will not cause total power dip. Widely used for protection of sensors and actuator / solenoid valve circuits in automation control cabinets.
