Product Features
The GDL7-125 AC miniature circuit breaker (MCB) provides dependable overload and short-circuit protection in both commercial and industrial electrical systems.
Built with high breaking capacity (6kA/10kA) and rated current up to 125A, it offers excellent protection performance and long service life.
With compact modular design, IP20 protection, and 1P/2P/3P/4P configurations, it’s ideal for low-voltage AC systems, switchboards, and control panels.
Engineered with thermo-magnetic tripping (B, C, D curves), it ensures accurate protection under various electrical conditions.
