Zero-cross turn-on
3) Feature: -02 = Control LED: Standard on all ST48D
Only available on ST24D 12A and 40A (standard)
-16 = Internal MOV: Available only on ST24D 25A and 50A
-22 = 24 Vac Control
MECHANICAL SPECIFICATION
DESCRIPTION
The Series ST single-phase relays are designed for
high-power applications. The design incorporates an
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
available on ST24D 25A and 50A models.
