TPW3 Series ACB Air Circuit Breaker for Low Voltage Distribution
Reliable low voltage air circuit breaker for intelligent circuit protection and power distribution in industrial, commercial, and building electrical systems.
The TPW3 Series ACB air circuit breaker is engineered for low-voltage power distribution systems requiring reliable protection and stable operation. Suitable for AC 50/60Hz systems with rated voltages of 400V and 690V and current ratings from 200A to 6300A, it provides effective protection against overload, short-circuit, undervoltage, and earth fault conditions. With intelligent and selective protection functions, it helps improve electrical system safety, maintain power continuity, and reduce unnecessary downtime. Widely used in industrial plants, power stations, mines, and smart building projects, the TPW3 air circuit breaker meets IEC/EN 60947-2 standards.
