TPN B-Curve Miniature Circuit Breaker is designed for three-phase electrical systems requiring complete phase and neutral isolation. With B-Curve tripping characteristics, it offers fast response to overload and short-circuit faults, making it suitable for low inrush current applications in commercial and light industrial installations.
This MCB ensures simultaneous disconnection of all three phases along with neutral, enhancing operational safety and protecting equipment and wiring from electrical damage.
