DORMAN K3PB50 MCB TP Type B 50A 10KA

Dorman K3PB50 MCB | TP Type B 50A 10kA

Deliver robust protection for high-power three-phase circuits with the Dorman K3PB50 MCB. This is a Three-Pole (TP) Type B miniature circuit breaker, rated at 50A with a high 10kA breaking capacity. Engineered for demanding industrial and commercial applications. Provides reliable, simultaneous protection across all three phases against overloads and short circuits for heavy-duty motors, machinery, and distribution systems.

Key Features & Benefits:

• High-Current Three-Phase Protection that prevents damage from phase imbalance and overload.
• Superior 10kA Breaking Capacity: suitable for installations with higher prospective fault levels, safeguarding equipment and cabling.
• Type B Tripping for reliable thermal-magnetic protection: ideal for three-phase circuits.
• Simultaneous Three-Phase Disconnection. Guarantees all three live conductors are disconnected together during a fault (critical for the safety of personnel and the operational integrity of three-phase equipment).
