PC + MCC withdrawable switchboard for 660 V / 3150 A systems — 80 kA/1 s horizontal-bus withstand, IP40, many circuits per cabinet with local/remote/automatic operation.
GCK low-voltage withdrawable switchgear comprises Power Center (PC) and Motor Control Center (MCC) sections, serving power plants, substations and industry on AC 50 Hz systems up to 660 V and 3150 A — converting, distributing and controlling energy for power distribution, motor control and lighting.
GB/T 7251.2-2023 LV switchgear and controlgear assemblies — Part 2
High breaking capacity and dynamic-thermal stability; advanced rational structure with practical electrical schemes
Strong serialisation and universality — scheme units combine freely; one cabinet holds many circuits, saving floor space
Elegant appearance, high protection grade, safe, reliable and easy to maintain
Altitude ≤ 2000 m; ambient ≤ +40 °C (24 h average ≤ +35 °C), not below −5 °C
Clean air; RH ≤ 50 % at +40 °C (e.g. 90 % at +20 °C); tilt ≤ 5°
