MCB 0.5 A to 63A Three Pole C Curve

Inclusive of all taxes

The Three Pole Miniature Circuit Breaker (MCB) with a C Curve characteristic offers rated currents ranging from 0.5 A to 63 A, specifically engineered to provide reliable protection against overload and short circuit conditions in motor circuits and other inductive loads. Designed to meet IS/IEC 60898-1 standards, this MCB features safety terminals that effectively guide cables towards cage terminals, reducing the risk of improper cable termination and enhancing installation safety. The large cable terminals support both copper and aluminum cables up to 35 mm², enabling versatile application in diverse electrical systems. The breaker incorporates a precise hammer action mechanism where a hammer attached directly to the plunger strikes the moving contact arm with force proportional to the fault condition, ensuring rapid and consistent tripping performance. It also includes a bistable dual-position DIN rail clip, facilitating easier installation and removal without disassembling adjacent components. Optimized for low power consumption, this MCB provides an energy-efficient and cost-effective solution for electrical circuit protection in commercial and industrial environments. Its robust design ensures durability and long-term performance in demanding conditions.
