What is Vertical Type Fused Load Separator?

In 3-phase AC circuits, it provides safe separation of rated currents under load in accordance with the category of use and operating voltage, protection against overload currents and short circuits.

Why Should We Use Sigma Vertical Type Fused Load Separator?

Maintenance and repair costs are much lower than thermal-magnetic switches, NH fuses, which ensure safe interruption of current, can be easily replaced.

The response time to short-circuit current is much faster than that of thermal-magnetic switches. (Thermal-magnetic switches cut the short-circuit current by about 10 ms and sigma switches by about 1 m) and there is no severe deformation that causes injuries at the time of short-circuiting.

The cutting capacity is much higher than thermal magnetic switches (100kA).

Thanks to the parking position feature, we ensure the maintenance and repair safety of Sigma Vertical Type Insured Load Separators.

General Structure of Sigma Vertical Type Fused Load Separators

Sigma Vertical Type Fused Load Separators;

• Design suitable for NNH000, NH00, NH1, NH2, NH3 fuse use.
• They can open the 3 phases together or separately.
• It has high cutting capacity.
• The arc formed by the arc separators is prevented from damaging the cutter.
• The body material is made of fireproof BMC material with very high mechanical and electrical insulation properties.
• The plug-holder contacts are silver-plated.
• It can be observed from the outside that the fuse wire melts.
• Power losses are low.
• It is possible to measure the currents of each phase with current transformers.
• Thanks to the lower body designed for ease of installation in the enclosures, the depth difference between 160A and 250,400,630A has been eliminated.
• The conductor busbars carrying current in the 250,400,630A group are manufactured as a monolith instead of riveting to prevent power losses that cause heat increase.
• Compliant with AC23B/AC22B/AC21B usage class
• All plastic parts used are made of thermoplastic raw material with V0 flammability property.
• All fasteners (bolts, washers,..) are made of corrosion-resistant stainless steel material.
