This Brazilian standard three cylinder grounding power plug strictly follows the Brazilian NBR 14136 electrical standard production, has passed INMETRO complianCE Certification, and is compatible with Brazil's 127V/220V 60Hz civil and commercial power supply networks. It is a standard power supply access component for metal shell electrical equipment, widely used in household appliances, office equipment, kitchen appliances, and other products. It is the mainstream compliant plug-in component for exporting electrical appliances to the Brazilian market.

The plug adopts a three pole structure with three cylinders arranged in parallel. The length of the grounding pin in the middle is significantly longer than that of the neutral pins on both sides. When inserting into the socket, the grounding circuit is first conductive, and when unplugged, it is finally disconnected, forming a safety logic of "grounding first, power on later; power off first, ground off later". When metal casing equipment such as refrigerators, washing machines, air conditioners, and computer hosts experience insulation damage or leakage faults, the grounding circuit can instantly discharge the fault current, effectively avoiding the risk of electric shock to the human body and fully meeting the safety requirements of mandatory grounding for Class I electrical appliances in Brazil. All key dimensions such as the diameter and center to center spacing of the pins fully comply with Brazilian national standards, and can be smoothly connected to all compliant Brazilian standard three hole wall sockets and mobile plugs. The universal interchangeability is strong, avoiding safety hazards such as loose insertion, virtual connection heating, and poor contact caused by non-standard parts from the root. The end of the pin is treated with a rounded guide angle, making insertion and removal smoother and less likely to scratch the inner wall of the socket, improving the feel and durability of use.

The plug housing adopts integrated injection molding technology, and the overall structure is tight and seamless. The front of the shell is designed with a horizontal anti slip texture to increase grip friction, making it easy to insert and remove without slipping. The INMETRO compliance mark, rated electrical parameters, and origin information are clearly engraved on the end face, fully complying with the labeling specifications of Brazilian electrical products, facilitating product compliance circulation and rapid identification of specifications. The tail integrated hollow stepped anti bending wire protection structure evenly disperses the stress generated by wire pulling and repeated bending through multiple layers of circular grooves, effectively alleviates the fatigue loss at the root of the wire, reduces the occurrence of internal copper wire breakage and outer sheath cracking, and significantly extends the service life of the supporting Power cord. Internally equipped with a dedicated locking wire fastening structure, the pins and cores are firmly connected using precision cold pressing technology, with tensile performance meeting standards. It is not easy to cause core loosening or terminal detachment during daily dragging and bending, ensuring long-term electrical connection stability.

The conductive pins are made of high-purity copper alloy substrate and precision processed. The surface is uniformly plated with nickel for oxidation resistance, with low conductivity loss and low contact resistance. Under rated load, the temperature rise is stable under long-term power on conditions, and it is not easy to oxidize, rust, or ignite the contact. Even after thousands of repeated insertions and removals, it can still maintain tight and reliable contact performance. The insulation shell is made of engineering plastic that meets Brazil's flame retardant requirements. It has high electrical insulation strength, excellent impact resistance, and resistance to high and low temperatures. It can quickly extinguish itself in the event of external open flames and fully isolate internal live parts, effectively preventing electric shock and fire risks.

The mainstream rated specification of the product is 10A 250V, which can cover the current carrying requirements of most household and commercial appliances. It can be integrated into finished power cords as an original factory accessory, as well as used for customized wire processing and replacement of old equipment. It is a safe, compliant, and widely applicable standard power plug component in the Brazilian power supply system.
