巴基斯坦采购需求：上锁挂牌、安全挂锁、阀门上锁、电气上锁、上锁站、BOZZYS

I'm looking for a lot of lock devices specifically designed for circuit breakers, particularly for MCCBs in a range of 50A to 250A and extending from 250A to 630A. The devices should be universal type, featuring a dovetail design for easy installation and compatibility across different breakers. It's important that the materials used are high-quality; I require reinforced nylon combined with copper for durability and optimum performance. Additionally, the color should be red for easy identification. Please provide details on your available options, including pricing, lead time, and any relevant certifications. Thank you!
