Technology Advantages
Silent Box-Type Design
The SB30/GCB50 features a fully enclosed bracket system that encases the breaker's main body, providing multiple critical functions:
Noise Attenuation: The enclosed structure acts as a sound-dampening barrier, significantly reducing operational noise levels to 109 dB
Dust Containment: The box-type design helps contain dust and debris generated during operation
Vibration Damping: The enclosed bracket incorporates damping modules that protect internal components from excessive vibration
Nitrogen-Powered Mechanism
The breaker utilizes compressed nitrogen gas as a return spring mechanism, offering several advantages:
