## **New Product Features & Benefits** 

 **G9KA-E is the Higher Capacity version of G9KA moving from 800VAC, 200A to 1000VAC, 300A.** 

 **The Ultra-Low Contact Resistance of ≤0.2mΩ spec generates low heat on the PCB.** 

 **G9KA-E’s 300A/1000VAC is the highest capacity spec in the market PCB relays[(*1)] .** 

(*1) as of Jan 2023, according to our research 

Unique[(*1)] Structure of Double Brake & Twin Contacts to realize **Lower Contact Resistance of ≤0.2mOhm** 

Plun ger-type Relay Structure to realize **Higher Endurance** with **Lower Power Consumption** 

Contact Material with High Electrical Conductivity to realize **Lower Contact Resistance** 

Well-Designed Terminals to realize **Higher Heat Radiation** (keep the Temperature Low) 

## **Application Case / Grid-tie Inverter for PV and ESS** 

 **G9KA series can be applied to Inverters for PV & ESS to disconnect from the grid** 

 **G9KA-E is suitable to be used in 200-400kVA/600-800VAC designs. By replacing conventional contactors, it can be Smaller Size, Lighter Weight and Provide Ease in Assembly moving from screws to PCB.**

## **Caution for Shock Resistance** 

- **As with G9KA, Shock Resistance should be taken into account to use G9KA-E.** 

- **Even when the relay is on, the resistance to malfunction impact differs depending on the mounting direction, so please use it after understanding by the customer.** 

- **Please also check the datasheet about shock resistance.** 

## **Caution for Holding Voltage** 

- **As with G9KA, Holding Voltage should be used for G9KA-E.** 

 **This allows customers to reduce coil power consumption by approximately 80%.** 

 **Please also check the datasheet about holding voltage.** 

## **Warnings/Precautions** 

- **As with G9KA, G9KA-E operates High Current so please explain the below to customers.** 

 **As with G9KA, G9KA-E also requires an ACS (Application Check Sheet) submitted to Omron for approval before proceeding with the purchasing order.** 

- `【` **Warning** `】` 

   - **Do not connect to individual relays by probes or by socket. Abnormal heat may be experienced by insufficient connections.** 

   - **If a large current is applied while the mounting is uncertain, there is a risk of abnormal heat generation.** 

   - **Do not use dropped relays, as the shock may cause improper relay operation.**
