A 10-25A shuttered socket is a type of electrical socket that can handle both 10 Amp and 25 Amp loads, and it includes a side shutter mechanism for added safety, particularly to prevent children from inserting objects into the socket. These sockets are commonly used for a variety of appliances, including those with higher power requirements like geysers and air conditioners. 

Key Features:

Dual Current Rating: Can safely handle both 10A and 25A devices. 

Shuttered Design: Features a side shutter mechanism that covers the live contacts when a plug is not inserted, enhancing safety and preventing accidental contact with electricity, especially important for child safety. 

High Withdrawal Pull: Often utilizes a flexible brass connector encased in an engineering plastic cage to ensure a secure and reliable connection when plugging and unplugging. 

Terminal Connection: Typically uses screw-type terminals, allowing for connection with solid, multi-strand, and flexible wires. 

Durable Material: Made from materials like Polycarbonate, which is UV stabilized to prevent discoloration and maintains a glossy finish.

Fire Retardant: Some models are designed with self-extinguishing properties and are tested to withstand high temperatures (e.g., 850-degree glow wire test). 

Endurance: Tested for a high number of electrical operating cycles (e.g., 20,000) to ensure long-term reliability.
