High-current industrial grade SSR GYSSR-300DA(H3)
Operation Notice
1. Resistive load could not exceed 60% of the rated current. 
2. Inductive or capacitive load could not exceed 40% of the rated current. 
3. Electric machine load could not exceed 20% of the rated current. 
4. Proper radiator adapted to the working requirement of solid state relay should be equipped, the allowance should be widened when the load radiating condition is not so good. Short-circuit load is not allowable. 
5. Over current protection: Over current and short circuit are the main reasons for permanent damage of output controllable silicon in the SSR, and using fast fuse and air switch is one of methods for over current protection, fuse is also available for small capacity. 
6. Over voltage protection: It can adopt parallel voltage-dependent resistance(MOV), the MOV area decides
The absorption power, while its thickness decides the protective voltage value, generally, 471/10D voltage-dependent resistance for 220V series SSR, 681/10D voltage-dependent resistance for 380V series SSR, 
821/10D voltage-dependent resistance for 480V series SSR.

Order Key

Please confirm the practical working voltage load power and control method before selecting, 
Make sure that the load current do not exceed the allowance of SSR. 

Single Phase: Resistive load power(KW) *9=SSR Ampere
For example: Suppose the resistive load power is 3KW, we should select the SSR Ampere ›27A
Three Phase: Resistive load power(KW)*3=SSR Ampere
For example: Suppose the resistive load power is 3KW, we should select the SSR Ampere ›9A
