The heatsink of the curves is dedicated for the SRH2/SRH3.
※
Install SR2/SR3 Series on the metal plate (min. 130mm×120mm).
Since eectiveness of the heat radiation is decreased when multiple SSRs are installed closely, please supply less than 50% of the rated load current.
※
Above SSR derating curves obtained approval from the UL certication authority.

Proper Usage
Cautions during use
1. Follow instructions in 'Cautions during Use'. Otherwise, it may cause unexpected accidents.
2. 4-30VDC, 24VAC signal input should be insulated and limited voltage/current or Class 2, SELV power supply device.
3. Attach a heat sink or install the unit in the well ventilated place.
To attach the heat sink, use Thermal Grease as below or that of equal specication.
※
Thermal Grease: GE TOSHIBA (YG6111), KANTO-KASEI (FLOIL G-600), SHINETSU (G746)
4. Ground to the heat sink, panel, or DIN rail. Failure to follow this instruction may result in electric shock.
5. While supplying power to the load or right after turning o the power of the load, do not touch the body and heat sink.
Failure to follow this instruction may result in a burn due to the high temperature.
6. In order to protect the product from the short-circuit current of the load, use rapid fuse of which I2t is under the 1/2 of
SSR I2t. When short-circuited, replace the fuse to those of same specication with the used rapid fuse.
7. Install dummy resistance in parallel with the load, to keep the sum of current owing in the load and dummy resistance
being over SSR minimum load current.
8. When using random turn-on model for phase control, install noise lter between the load and the power of the load.
9. Do not use near the equipment which generates strong magnetic force or high frequency noise.
10. This unit may be used in the following environments.
①
