Medium Voltage Switchgear Components
Ready to overcome the challenges of building efficient, dependable medium voltage panels and switchgear?
We provide best-in-class core components that help panel builders and distributors streamline assembly, accelerate project timelines, and ensure uncompromising quality. Simplify your switchgear completion process and deliver exceptional performance with solutions you can trust.
Our comprehensive range of key components includes:
- Circuit Breakers: Protective devices that automatically disconnect circuits in the event of a fault, thus preventing damage to the installation and ensuring a safer system.
- MV switches and disconnectors: Indoor switchgear designed to switch and operate energised and de-energised electrical circuits under load conditions.
- MV fuses: Protective components that blown to interrupt the flow of current in electrical systems when a fault occurs, helping to protect equipment such as transformers or electrical grid.
- Protection and control, metering and feeder automation: Protection relays, Arc flash and Metering devices enable monitoring and control of switchgear by detecting abnormal operating conditions, helping to prevent severe damage and reduce the need for unplanned maintenance.
Switchgear is more than a protective device. It's a critical part of keeping our power grids reliable and resilient.
A circuit breaker is an automatically operated electrical switch designed to protect electrical circuits from damage caused by overloads or short circuits. Its primary function is to interrupt current flow when a fault is detected, preventing equipment damage and improving safety.
What is a Vacuum Circuit Breaker? A vacuum circuit breaker interrupts current flow through arc quenching in a vacuum chamber. The fixed and moving contacts are enclosed within a permanently sealed vacuum interrupter, ensuring reliable operation and reduced wear on components.
Applications of vacuum circuit breakers:
- Commonly used for voltages up to 40,500V, making them ideal for medium-voltage power systems
- Widely deployed in industrial plants, utilities, and infrastructure requiring dependable switching
- Suited for environments where long service life and low maintenance are critical
Benefits of Schneider Electric vacuum circuit breakers:
- Longer service life compared to other breaker types
- Minimal maintenance requirements, reducing operational costs
- Reliable fault interruption with fast arc quenching in a vacuum chamber
- Safe and efficient performance in medium-voltage networks
- Environmentally friendly technology with no harmful gases
Choose Schneider Electric vacuum circuit breakers for proven durability, efficiency, and protection in medium-voltage power distribution systems.
