Description
Autonics SRH2/SRH3 Series Solid State Relay
SRH3-4475 Solid State Relay, Integrated Heatsink Type, 3-Phase(3-Pole), Input 90-240VAC, Load 48-480VAC, 75A, Zero Cross Turn-On
The SRH2/3 series three-phase solid state relays are integrated heatsink types, which are removable. The solid state relays can control 2-phase or 3-phase loads and feature two mounting hole types for compatibility with various types of heatsinks. The series also features alarm output for safe operation, and are also available in 24 VAC low voltage models. Select models feature high dielectric strength of up to 4000 VAC and integrated heatsink models can be mounted on to both DIN rails and panels.

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. When attaching the heat sink, use the heat sink grease.
※Heat sink 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 off 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 specification with the used rapid fuse.
7. Install dummy resistance in parallel with the load, to keep the sum of current flowing in the load and dummy resistance being over SSR minimum load current.
8. When using random turn-on model for phase control, install noise filter 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 Indoors (in the environment condition rated in ‘Specifications’)
② Altitude max. 2,000m
③ Pollution degree 2
④ Installation category III
