PHOENIX_CONTACT
1-channel electronic equipment protection switch to protect consumers on 24 V DC in case of overload and short circuit. Easy potential distribution with the components of the CLIPLINE complete rail terminal system. With electronic locking of the set nominal currents. The warning contact is opened when the channel is switched off due to a fault or manually. For installation on DIN rails.
1-channel, electronic circuit breaker for protecting loads at 24 V DC against overload and short circuit. Easy potential distribution with components from the CLIPLINE complete terminal block system. With electronic interlock of the set nominal currents. The signal contact opens if the channel has been switched off manually or due to a fault. For installation on DIN rails.
