The design incorporates an .77 (19.6) .19 (4.7) M4 SCR or triac output. The Series ST relays utilize optical isolation to protect the control from load transients. Control LED is available on certain models. All Series ST relays are zero crossing. Internal MOV is also 1~ 2~ available on ST24D 25A and 50A models. APPLICATIONS 4- 3+ Heating control Industrial and process control On/Off controls of AC equipment 1.02 (25.8) 1 (25.4) 1.75 (44.5) APPROVALS TOLERANCE: .01 (0.3) M3 WEIGHT: 3.18 oz. (90g) All models are UL recognized. UL File Number: E128555.
