Eaton's power lock devices are designed for safety, energizing within a chamber to eliminate the possibility of exterior arcing. The chamber is protected by a spring-loaded safety shutter that ejects the plug if it's not fully locked in place. The shutter also prevents the entrance of foreign matter and provides an IP30 finger-safe rating. These devices are ideal for high-abuse industrial and specialized hospital applications. Designed with the latest in ergonomic shape, the power lock devices provide a superior design and performance, making them ideal for many applications. The devices are available in a wide range of non-NEMA configurations.
