The choice of housing material in electrical product design directly impacts the product's safety, durability, appearance, and cost control. Different plastic materials possess distinct characteristics, making them suitable for various usage environments and functional requirements. This article provides a detailed analysis of six commonly used engineering plastics—PA, PC, ABS, PP, PVC, and PET—focusing on their advantages, disadvantages, and suitable applications in housing design.

This article explores the core knowledge of these devices, specifically fridge guard and TV guard units, to help you scientifically safeguard your home's electrical system.

The core mission of a Surge Protective Device (SPD) is to neutralize voltage and current surges that far exceed normal levels within microseconds or even nanoseconds. Today, we will take you deep inside an SPD to see how components with different characteristics work together in precise coordination to complete this ultra-fast protection.

Thunderstorms, air conditioner startups, power grid fluctuations... These can all trigger deadly power surges (instantaneous high-voltage pulses) in your home circuits. Precision electronics like TVs and computers are highly vulnerable to damage. Selecting a suitable home surge protector establishes the first line of defense for your valuable appliances. This article outlines common types of home surge protectors and key selection criteria.

When you purchase a surge protector (also known as a surge suppressor or lightning protection power strip) for valuable home appliances like your TV, computer, or refrigerator, you'll always notice a prominent parameter: the Joule Rating (e.g., labeled as "140J", "540J", "918J"). What exactly does this number represent? Why is it so important? This article will provide a clear explanation.

Voltage protectors act as critical defense systems against power anomalies, but their effectiveness hinges on proper delay configuration. The delay setting – the time between fault-triggered shutdown and automatic restoration – is not a one-size-fits-all parameter. Understanding the distinct roles of 5-second (5s), 30-second (30s), and 5-minute (5m) delays ensures your equipment receives tailored protection.

The voltage protector (also known as an over/under-voltage protector) is a crucial guardian for your home appliances' safety. When it detects dangerous situations like excessively high voltage (overvoltage) or low voltage (undervoltage), it immediately cuts off the power supply to prevent appliances from being burned out or damaged. But have you noticed the delay options usually labeled "5S", "30S", or "3M" on the protector?

The unseen sentinel of modern power systems, the DIN-Rail Voltage Protector integrates seamlessly into distribution cabinets to deliver mission-critical protection. Engineered to continuously monitor voltage and disconnect power within milliseconds when dangerous over-voltage or under-voltage occurs, it shields sensitive equipment—from industrial robotics to household appliances—against damage, downtime, and safety hazards.
