Air Insulated Switchgear Product Value

How can a product add value?

1. By reducing the total cost

2. Or by increasing revenues

UniGear ZVC adds value by:

1. Occupying minimum floor space

2. Reduced size of motor cables

3. Higher performance and availability

Air Insulated SwitchgearComparisons

Comparison of performance

Evaluating UniGear ZVC Fused Vacuum Contactor technology to conventional Circuit Breaker technology for switching applications:

Back to Content

UniGear ZVC

Fault current limited due to HRC fuses.

Fault clearing time is typically <5ms at full fault current.

Reduced let through energy allows reduced cable size.

Reduced thermal stresses on motor and rapid fault clearing time minimise damage.

Up to 1,000,000 op. provides extended service life.

Small footprint totalling 0.42 sq m.

Circuit Breaker

No fault current limiting capability.

CB fault break at first natural current zero 200ms.

Cable needs to be sized to maximum system short circuit level.

Thermal stresses consistent with system short circuit level and clearing time result in severe damage.

Up to 30,000 operations service life.

Average footprint 1.05 sq m.
