Instanta XETR6SP Over Boil Cut-Out CB02863, CB05128, CB02833 - Genuine Replacement Spare Part
The Instanta XETR6SP Over-Boil Cut-Out is a genuine safety component used in compatible Instanta CB series water boilers. It is designed to protect the appliance by detecting unsafe over-boil conditions and interrupting operation to prevent damage and maintain safe use.

This component is compatible with models CB02863, CB05128, and CB02833, making it a critical part of the safety system within these units. It ensures the appliance can operate safely in demanding commercial environments.
