Phoenix Contact CBMC E4 24DC/1-10A NO Electronic Circuit Breaker 2906032
Introduction
Four loads at 24 V DC are protected by the Phoenix Contact CBMC E4 24DC/1-10A NO multi-channel electronic circuit breaker against overload and short circuit. with the specified nominal currents being electronically locked. to be mounted on DIN rails.
Product features
•Unit replacement without re-planning is made simple by the compact design and customization choices.
•A single push-button LED allows circuits to be changed without the need for equipment.
•Electronic locking provides dependable security against unintentional changes to existing values.
•Traffic light-colored status LEDs provide real-time operational condition assessment.
