PTCB E1 24DC/0.1-0.63A NO - Electronic circuit breaker
Single-channel, electronic device protection for 12-24 V DC loads. Nominal current adjustable from 0.1-0.63 A. With remote signaling and active current limitation. Can be combined with CLIPLINE terminal blocks. For installation on DIN rails.
- Precise fault localization and fast recovery thanks to status message and local and remote reset options
- Effortless system planning with precise shutdown, low voltage losses, and adjustable current values
- More space in the control cabinet due to integrated potential distribution of positive and negative in 6 mm
- Simple application setup due to bridging option to CLIPLINE complete terminal block system
