Siemens 3VA11 underload disconnect switch: power and reliability in a single module
The Siemens 3VA11 is a 4-pole MCCB molded case circuit breaker with a current rating of 160A. It is designed to function as an underload disconnect, main, safety and emergency switch, offering maximum versatility in industrial switchboards and high-performance installations.
Safety and durability in demanding environments
Fixed flush-mounted design with front clamp connections ensures ease of installation and long-term reliability. With impulse withstand voltage up to 8 kV and conditional short-circuit protection up to 70 kA (with NH fuses), the device offers high operational safety in demanding industrial environments.
Without circuit breakers: pure and direct disconnection
This model has no overload or short-circuit protection, making it perfect for pure disconnection functions where protections are already guaranteed upstream. It is also ideal as a maintenance or repair switch, with clear indication of the switching status via ON, TRIP, OFF lever.
