• NNH000, NH00, NH1, NH2, NH3 Design suitable for insurance use.

• They can open the 3 phase together or separately.

• It has high cutting capacity.

• ARK is prevented from damaging the cutting with arc sepretors.

• The body material is made of fireproof BMC material with a very high mechanical and electrical insulation feature.

• Knife insurance holder contacts are covered with silver.

• It can be observed from the outside that the knife insurance wire melts.

• Power losses are low.

• With the current transformers placed in the rear buses, it is possible to measure the currents of each phase.

• The depth difference between 160a and 250,400,630a was eliminated thanks to the lower body designed to provide ease of assembly on the panels.

• Conducting bar carrying current within the 250,400,630A group has been manufactured as monolithic instead of riveting to prevent loss of power that causes heat increase.

• AC23B/AC22B/AC21B is suitable for use class.

• All plastic parts used are made of thermoplastic raw material with V0 flammable properties.

• All fasteners (bolts, rondela, ..) Made of corrosion -resistant stainless steel material.

• Parking position feature Sigma Vertical Type Insured load separators are provided with maintenance and repair safety.

Why should we use the sigma vertical type insured load separator?

• Maintenance and repair costs are much lower than thermal-monitor switches, NH fuses that provide safe cutting of the current can be easily changed.

• Reacting to the short circuit current is much faster than thermal-monitor switches. (Thermal-Magnetic switches cut the short circuit current in about 10 ms and Sigma DSAs cut approximately 1 ms) and the ark causes accidents in the event of short-circuit cutting.

• Cutting capacity is much higher than thermal magnetic switches (100ka).
