Jean Muller KETO-00 Fuse Switch Disconnector
The KETO-00 Fuse Switch Disconnector is a DC isolation and protection device designed for battery energy storage systems. It provides a safe means of disconnecting the DC battery circuit for maintenance while protecting the system with a replaceable fuse.
Required when installing two Dyness batteries in parallel, the KETO-00 ensures the battery installation meets recommended protection requirements by providing individual circuit isolation and overcurrent protection. Its compact DIN rail design allows for quick installation within a suitable enclosure and helps improve the safety, reliability and serviceability of residential battery storage systems.
Built for demanding DC applications, the KETO-00 is suitable for use with compatible low-voltage battery systems and hybrid inverters, making it an essential accessory for larger Dyness battery installations.
