Structural Features
KSO 210 (310) cubicles are designed with compactness, safety, and ease of maintenance in mind. Their construction ensures reliable placement of all necessary components and easy access for repair and maintenance work. A high degree of protection and thoughtful arrangement of elements guarantee durability and safe operation.
- Installed indoors in temperate climates (from -25°C to +40°C).
- Available with IP20 or IP54 protection ratings.
- Inside the cubicles, the main network equipment is located, including autogas load break switches, disconnectors with grounding blades, vacuum circuit breakers, voltage transformers, and auxiliary transformers.
- KSO 210 cubicles with a vacuum circuit breaker are equipped with a protection package (overcurrent, overload, etc.).
- Connection to the external network is done by cables (up to four cables with a cross-section up to 185 mm²) or busbars (for cubicles 24 and 17V).
- Two-row installation with a bus bridge (ShMR or ShM) is possible, installed on the end cubicles.
- Models for outdoor installation (U1 execution) and variants with reduced width (650 mm) for confined spaces are offered.
