Specially designed for safe use in solar systems, Sigma 800V AC NH Fuses are from the group of fuses with melting wires and ensure that the wire inside melts under the effect of heat and breaks at different points against overload currents and short circuits, and quartz sand fills the gaps between the broken parts, completely cutting off electrical conduction and providing the necessary protection.

Increased safety is provided with the steatite body material, which is extremely resistant to short circuits, pressure and high temperatures. Thanks to the double indicator structure, it is easily observed that the NH fuse is disabled, thus providing less downtime and less cost.

800V AC  Surge Protection Device For String Inverter Protection  is specially designed to protect string inverters in solar energy systems.

Soligma Series LV Moulded Case Circuit Breakers are specifically designed for 800V AC solar energy systems and having superior features, they safely perform the switching and protection function of the systems they are connected to.
Soligma Series LV MCCBs are manufactured in accordance with IEC/EN 60947-2 standard and can break short circuit currents up to 150kA and can be used safely at high ambient temperatures via their special thermal resistance design

Soligma Series 800V AC Horizontal Type Switch Disconnectors, 
specially designed for Solar Systems, are electrical circuit protection and control elements that, when used with NH fuses, enable the circuit to be manually opened and closed, as well as to safely cut off the circuit in the event of any short circuit or overload current.

• Soligma Series Horizontal Type Switch Disconnectors, are manufactured in accordance with TS EN 60947-3 standards and CE norms. The body material is made of thermoplastic material resistant to 960 degrees, and the current-carrying sections are 99.9% pure electrolytic copper.

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.
