Brand & Origin: Produced and supplied by BSUMWELL-POSHER ELECTRIC (China), it is a core product under the brand's PS-KT series of waterproof junction boxes.
Core Material: All models are uniformly made of ABS or PC plastic. The material combines "lightweight" and "durability" properties, facilitating transportation and installation while withstanding long-term environmental wear.
Certification Standards: The entire series has passed CE Certification (complying with electrical safety standards) and ROHS Certification (meeting environmental requirements with low harmful substances), satisfying basic domestic and international usage regulations.
Protection Rating: Fixed at IP65, it can effectively block rainwater and dust intrusion while resisting mild corrosion, serving as a core guarantee for adapting to multiple environments.
Size Range: Covering the full spectrum from "small" to "medium". The smallest model is PS-KT 090605G (dimensions: 95×65×55mm), and the largest is PS-KT 382818G (dimensions: 380×280×180mm), which can match electrical wiring needs of different scales.

Strong Environmental Adaptability: Relying on the IP65 protection rating, it can be directly used in outdoor rainy environments, underground humid environments, and indoor damp areas (e.g., near bathrooms), preventing electrical short circuits caused by water and dust intrusion.
Flexible Installation Methods: It supports three mainstream installation methods — ceiling recessed mounting (for lighting control), underground wiring mounting (for landscape cables), and surface wall-mounted mounting (for outdoor sensors) — without the need for additional customized accessories.
Wide Application Scope: The lightweight design (single box weight ≤ 2kg) is suitable for household DIY projects (e.g., garden wiring), while the durable material meets the commercial project needs of professionals (e.g., switch protection in small stores), catering to both "personal" and "professional" requirements.
Indoor Scenarios: Wiring protection for ceiling-mounted lighting control devices (e.g., centralized management of downlight circuits in living rooms and bedrooms).
Outdoor Scenarios: Wiring for outdoor temperature/humidity sensors, electrical connections for garden irrigation equipment, and wiring protection for courtyard landscape lights.
Underground Scenarios: Connection of underground landscape lighting cables and hidden wiring for sprinkler systems, preventing line erosion by underground moisture.
Commercial Scenarios: Power wiring for outdoor billboards in small convenience stores and community supermarkets, and terminal protection for door sensor circuits at entrances.
Household DIY garden wiring: Recommend PS-KT 13807G (dimensions: 130×80×70mm, price: $0.6-$2). The reason is that household gardens usually only require connecting 2-3 landscape light lines. This model is small in size and low in price, and can be directly buried in garden soil or mounted on tree trunks without occupying too much space.
Small commercial landscape lighting: Recommend PS-KT 251513G (dimensions: 250×150×130mm, price: $3.2-$5). The reason is that commercial landscapes (e.g., light strips at store entrances, landscape lights in small plazas) usually require connecting 5-8 lines. This model has sufficient internal space to accommodate line joints and small control modules, and its IP65 protection can cope with the open environment in commercial areas.
For ordinary users (household DIY scenarios): ① Material value: ABS/PC plastic is lightweight (single box weight ≤ 1kg), allowing ordinary users to complete installation independently without tool-assisted handling; at the same time, the material is anti-aging (can resist UV rays for more than 5 years when used outdoors), avoiding frequent replacements. ② Certification value: ROHS certification ensures that the material does not contain harmful substances such as lead and mercury, so users do not need to worry about "volatile harmful substances" affecting family health, especially suitable for families with children.
For commercial users (small commercial projects): ① Material value: The impact resistance of PC plastic (can withstand a 5kg weight impact without breaking) is suitable for public commercial places (e.g., store entrances, community plazas), avoiding damage to the junction box due to human collision. ② Certification value: CE certification complies with domestic electrical installation specifications. Commercial projects can directly provide certification documents during acceptance, eliminating the need for additional testing, shortening the project acceptance cycle, and reducing compliance costs.
