SM6-24 QM Modular Switchboard up to 24 kV – Air Insulated Switchgear with SF6
Description:
The SM6-24 QM is a modular, air-insulated switchboard designed for medium-voltage applications up to 24 kV. Developed by Schneider Electric, it utilizes SF6 breaking technology to ensure reliable performance in secondary underground distribution systems.
Key Features:
- Modular Design: The SM6-24 QM is composed of metal-enclosed switchgear and controlgear modular units, allowing for easy adaptation to specific requirements.
Rated Specifications:
- Current: Available in 400, 630, and 1250 A configurations.
- Short-Circuit Current: Capable of withstanding up to 25 kA.
- Internal Arc Withstand: Tested for 12.5 kA/1s and 16 kA/1s, with classifications IAC: A-FL and A-FLR.
Breaking Technology: Employs SF6 or vacuum breaking technology, depending on the configuration, to ensure safe and efficient operation.
Control and Protection: Equipped with Sepam and VIP relays, as well as Flair fault passage indicators, to enhance system protection and monitoring.
Applications:
- Medium-voltage sections in MV/LV transformer substations within distribution systems.
- Medium-voltage consumer or distribution substations up to 24 kV.
- Medium-voltage industrial switchboards.
