The NAT1-63H AC MCB is a versatile miniature circuit breaker available in single-pole, two-pole, and three-pole configurations. It provides reliable protection against overloads and short circuits across different types of electrical systems. The single-pole version safeguards one live wire, the two-pole protects both live and neutral wires, and the three-pole version is ideal for three-phase systems, offering comprehensive protection by breaking all live wires simultaneously. With a compact design, the NAT1-63H ensures easy installation and maintenance, making it suitable for residential, commercial, and industrial applications.
