Easy to install: with seamless shell, the overall size is small and compact, it is very easy to install, no matter whether it is a standard distribution box or a customized electric box is suitable. Shell material, the selection of high-quality flame retardant insulation materials, heat resistance and impact resistance effect is good.

2. Convenient installation: tunnel type terminal block crimping is more reliable. Suitable for low-voltage power distribution in civil housing, industry, construction and other fields.

3. Complete product series: ranging from 1A to 63A, it can meet the electricity demand of different family and office scenes. Plastic Miniature Circuit Breakers with overload, short circuit protection and control, isolation function, leakage protection and other protection functions.

Why Is the Plastic Enclosure So Important?

Unlike large-frame industrial-grade circuit breakers, miniature circuit breakers require the use of specialized engineering plastics.

High Insulation: The plastic enclosure provides superior electrical isolation, ensuring that users do not come into contact with internal live components when manually operating the toggle lever.

Flame Retardancy and Heat Resistance: PUGAO utilizes V0-grade flame-retardant engineering plastics. This means that even in the event of a severe internal arc fault, the enclosure will not self-ignite, effectively preventing the spread of fire.

Lightweight and Modular: The plastic material facilitates precision injection molding, allowing the circuit breaker to be manufactured with a standard 18mm width for easy snap-mounting onto a 35mm DIN rail.

Quality Control and Certification

Pugao strictly implements the quality control process: incoming material inspection → process inspection → finished product sampling → aging test → factory inspection. The Plastic Miniature Circuit Breakers has obtained ISO9001, ISO14001, ISO45001 management system or test reports, and continuously improves the production process and testing methods to ensure that each batch of shipments meets the standards.

Process Highlights

As a manufacturer with over a decade of accumulated expertise, PUGAO boasts mature processing techniques and technology. Our Plastic Miniature Circuit Breakers not only deliver reliable performance but also feature specialized surface treatments on their housings to ensure enhanced durability.

Anti-Aging Formulation

The housing material is infused with special additives designed to resist UV radiation and aging. Even when subjected to prolonged high temperatures within a distribution box, the housing remains free from brittleness or discoloration, guaranteeing the retention of its physical strength for 10 to 15 years.

Precision Injection Molding

We utilize fully automated injection molding machines for production. The housing features tight seams and a smooth finish, effectively preventing dust ingress into the internal precision mechanisms and thereby minimizing the risk of accidental tripping.

Laser Anti-Counterfeit Marking

Instead of relying on stickers that are prone to peeling off, we employ automated laser marking technology. All product parameters are directly etched onto the plastic surface, ensuring the markings remain clear, legible, and permanent.
