The CBMC E4 24DC/1-4A S-R is an electronic circuit breaker capable of safeguarding four individual loads at a rated voltage of 24 V DC. This device is engineered to activate in the event of an overload or short circuit, providing necessary protection for electrical installations. It supports a rated current adjustable from 1 to 4 A per output channel, accommodating varying load requirements.

Installation is streamlined on standard DIN rails, and the unit incorporates features such as a status output and reset input for enhanced functionality. Notably, the electronic locking mechanism secures the configured nominal currents, ensuring operational integrity.

Constructed with a robust design, this device operates within a temperature range of -25 °C to 60 °C and has a dielectric strength of up to 35 V DC within the load circuit. It is rated for a short-circuit switching capacity of 300 A and incorporates an integrated failsafe element. The circuit breaker achieves an efficiency of over 99% and has a typical power dissipation of 0.6 W in no-load conditions.

The CBMC E4 24DC/1-4A S-R is also compliant with relevant standards such as EN 50178, making it suitable for a variety of industrial applications.
