NPH8-40 Miniature Circuit Breaker (MCB) is designed for dependable protection in low-voltage distribution systems where safety and compact design are critical. Featuring a 1P+N double-breakpoint structure with ratings up to 40A and a 6kA breaking capacity, it ensures effective overload and short-circuit protection.

The integrated contact position indication window enhances operational safety, while the current-limiting contact system and magnetic arc-extinguishing technology reduce stress on downstream equipment during fault conditions. Constructed with high-grade flame-retardant PA nylon, the NPH8-40 offers excellent thermal and impact resistance.

Suitable for industrial panels, commercial installations, renewable energy systems, and infrastructure projects, this MCB delivers reliable protection, durability, and compliance-ready performance for global applications.
