SRH2-4430, Solid State Relay, Heatsink Type, 3-Phase(2-Pole), Input 90-240VAC, Load 48-480VAC, 30A, Zero Cross

Autonics SR2/SR3 Series Solid State Relay Autonics SR2/SR3 Series Solid State Relay x Solid State Relay, Integrated Heatsink Type, SSR, Integrated Heatsink Type, 3-Phase(2-Pole), Input 90-240VAC, Load 48-480VAC, 30A, Zero Cross Turn-On Three-Phase Solid State Relays (Integrated Heatsink Type) 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. Ordering Information Dimensions Detachable heatsink type Integrated heatsink (Rated load current 15A/30A/40A) Integrated heatsink (Rated load current 50A) Integrated heatsink (Rated load current 75A) Example of Connections 3-phase (2-pole) 3-phase (3-pole) delta connection (Triangle -connection) 3-phase (3-pole) star connection (Y-connection) ※For DC signal input models, 8 and 10 terminals are connected inside. ※For AC signal input models, 8 and 10 terminals are insulated inside. 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
