When sourcing ABB switchgear, the price is heavily influenced by technical parameters. You must verify the Rated Voltage (kV), Rated Current (A), and Short-circuit Breaking Capacity (kA). For instance, high-voltage gas-insulated switchgear (GIS) like the ABB ZX series will command a premium over air-insulated (AIS) models like the UniGear ZS1. Ensure the configuration includes protection relays (e.g., Relion series) and vacuum circuit breakers (e.g., VD4), as these components significantly impact the total cost.
