CHINT DZ158-125 -2-PoleOut of Stock

The Chint DZ158-125 2-Pole Miniature Circuit Breaker (MCB) is a robust, high-capacity protective device specifically engineered for heavy-duty commercial, industrial, and OEM applications. While standard MCBs max out at lower currents, the DZ158 series serves as a high-amperage solution, providing dependable overload and short-circuit protection for main distribution boards, sub-panels, and demanding motor control circuits. Compliant with international IEC/EN 60947-2 standards, this double-pole breaker delivers reliable circuit isolation, ensuring both equipment safety and operational continuity under heavy inductive and resistive loads. Key Features & Specifications1. High-Current Load ManagementDesigned for high-capacity circuits where standard modular breakers are insufficient. The DZ158-125 frame size supports a variety of heavy-duty ratings: Available Current Ratings ($I_n$): 63A, 80A, 100A, 125A 2. Premium Short-Circuit ProtectionFeatures a rated breaking capacity up to 10kA (DZ158-125H) or 6kA, enabling the device to safely interrupt significant fault currents and protect downstream wiring and connected machinery from catastrophic damage. 3. Comprehensive Dual-Pole IsolationThe 2-Pole configuration ensures complete electrical isolation by simultaneously disconnecting both current-carrying conductors, making it a highly reliable option for main incoming supplies or dedicated high-power machinery. 4.
