Soligma Series Air Circuit Breakers are specifically designed for 800V AC solar energy systems and are produced as a solution against overload currents, short circuit currents and ground faults in the system and
electrical equipment it is connected to with its superior features.
By their remote communication electronic trip unit and high short circuit breaking capacity 50kA, they operate faster detection and action in overload, short circuit and ground fault cases.

Soligma Series ACBs provide high protection in your system with its long-term inverse time delay overcurrent protection (Long Time Delay), short-term delayed overcurrent protection (Short Time Delay), opening feature in short circuit currents (Instantaneous Tripping Delay) and ground fault protection (Ground Fault Delay) features, in short, LSIG protection.

Soligma Series ACBs have MCR and HSISC instantaneous protection functions. MCR protection protects the circuit breaker connection capacity and prevents the circuit breaker from exceeding the limit during connection. The protection is operating at the moment of opening and closing of the circuit breaker (within 100ms). HSISC protection is operating at the ultimate load capacity of the breaker. It is used forprotection purposes to prevent the breaker from delivering current which exceeds the breaking limit and is activated 100ms after the breaker is shut.
