G7EB-A1-E2 has a 36.7 x 50mm footprint and is 40.2mm tall.
Circuit breaking life is 100 operations at 150A 480Vac or 30 operations at 150A 800Vac.
“The device is ideal for providing safe system operations with an emergency stop function, and eliminates the need for other breaking devices,” according to Omron.
In nominal conditions, it will have a predicted life of at least 30,000 operations at 800Vac. This is when making 40A, carrying 150A, then breaking 40A.
When used for dc, predicted life is 400 operations at 60V 150A and 6,000 at 60V 40A.
“G7EB-E2 is suitable for up to 100kW at three-phase 400Vac, 200kW at three-phase 800Vac and 7kW at 48Vdc,” said Omron.
There are two operating coil options: Nominally 12Vdc 41Ω (~292mA), and 24V 165Ω (~146mA). This is ~3.5W in both cases, more than other relays in the G7EB family.
Nominal voltage cannot be applied for more than 3s. After this it has to be reduced to a specified lower value (see data sheet). Drive also has to be modified if the relay is fixed in certain physical orientations.
Dielectric strength is 5kVac 50/60Hz for 1min between coil and contacts, and 2kVac between contacts.
Contact resistance for the PCB relay is 5mΩ and contact gap is 3.6mm.
“Its contact gap is compliant with the requirements of IEC 62109. In PV inverter applications, G7EB-E2 can potentially be used to connect and disconnect the main circuit to and from the utility grid,” said the company. “For industrial uninterruptable power supplies, its 50 to 100kVA output can be used to open or close input and output of AC main circuits. Alternatively it can be applied to 48Vdc battery and power supplies.”
