Realize 80A, power on, and cut off 20A
1 Extremely small power relay
|
|
| |
The features of the Omron Power Relay G4A are as follows
● Realize the opening and closing of the motor load with 80A, energization, and cut-off of 20A.
Although it is compact, it can achieve high capacity opening and closing and high durability.
● Comply with UL and CSA air conditioning specifications to ensure the insulation distance.
● High insulation structure with strong anti-interference is adopted.
● The standard is made of flux-resistant construction. |
