Go to the Cerbo GX product page, scroll down to downloads and download the datasheet, it gives the relay specs. [https://www.victronenergy.com/communication-centres/cerbo-gx](https://www.victronenergy.com/communication-centres/cerbo-gx) You will need to drive another relay. Beware, many people have burnt out Cerbo relays, but a relay with a flyback diode or add one yourself. See the FAQ > [@Using inverter / MPPT / GX device programmable relays with higher current, inductive or capacitive loads](https://community.victronenergy.com/t/using-inverter-mppt-gx-device-programmable-relays-with-higher-current-inductive-or-capacitive-loads/99): > > Many Victron products have programmable relays included which can be used to send signals between each other or to control small loads. These ae typically rated as for the Cerbo GX as DC up to 30 VDC: 6 A DC up to 70 VDC: 1 A AC: 125 VAC: 6 A There have been many reports within the community from people who have burnt out the contacts or welded the contacts closed in the programmable relays in their systems. This is often caused by connecting the relays to inappropriate loads, sometimes loa… --- _[View the full topic](https://community.victronenergy.com/t/relays-in-cerbo-gx-to-operate-wet-bay-heaters/12042)._
