SIEMENS 3AH VCB

Authorised MV Switchgear Spares: Siemens 3AH breakers refer to a series of medium-voltage vacuum circuit breakers manufactured by Siemens. The 3AH series is known for its reliable performance and is commonly used in medium-voltage power distribution systems, industrial applications, and infrastructure projects.

Here are some key features and characteristics of Siemens 3AH breakers:

1. Vacuum Interruption Technology: The 3AH breakers utilize vacuum interrupters as the arc quenching medium. Vacuum technology provides excellent dielectric strength and fast interruption of fault currents.
2. Medium Voltage Range: The 3AH breakers are designed for medium-voltage applications, typically ranging from 3.6 kV to 36 kV. They are available in various voltage ratings to suit different system requirements.
3. Compact Design: The breakers are designed with a compact and modular structure, enabling flexible installation in space-constrained environments. This makes them suitable for both indoor and outdoor installations.
4. High Breaking Capacity: Siemens 3AH breakers are capable of interrupting high fault currents, ensuring the safe and reliable operation of electrical systems. They offer different breaking capacities to accommodate various fault levels.
5. Advanced Protection and Control Features: The 3AH breakers often incorporate advanced protection functions, such as overcurrent and short-circuit protection, earth fault protection, and coordination with other protective devices. They may also feature intelligent monitoring and communication capabilities for remote operation and condition monitoring.
6. Maintenance-Friendly: The vacuum interrupters used in the 3AH breakers have a long operational life and require minimal maintenance, resulting in reduced downtime and lower lifecycle costs.
