Arc protection switchgear ECOS-C

short-circuitsingle-polemedium-voltage

Overview
The SF6-free medium voltage switchgear ECOS-C is rated up to 24 kV and, with a 240 mm field width, offers one of the most compact factory-assembled circuit breaker systems for industrial applications. Equipped with high-performance vacuum interrupters and Midel 7131 fluid insulation, the system is engineered for reliable short-circuit interruption and end-of-life recyclability.

Key features

• Free from SF6, fluoroketone and fluoronitrile — global warming potential GWP = 0.0
• Factory-assembled compact systems, 2 to 7 panels, 240 mm panel width
• Busbar and fields dimensioned for 630 A continuous current
• Encapsulated primary part with touch-proof protection, rated IP67
• Enhanced arc-fault safety via single-pole metal-encapsulated primary parts
• Fluid insulation Midel 7131 classified as non-hazardous by the Federal Environment Agency
• Circuit breaker with vacuum interrupters capable of switching up to 20 kA in 3 s
• ARC-capable stored-energy drive, up to 10,000 switching operations (M2)
• Suitable for operation at unrestricted site altitudes (>1000 m)
• Separate air-insulated, fault-proof measuring panel available

Technical specifications

• Rated voltage: up to 24 kV
• Panel (field) width: 240 mm
• Continuous current rating (busbar): 630 A
• Short-circuit breaking capacity: 20 kA (3 s)
