REL-PR3- 24DC/3X21 - Single relay

2903702

Plug-in high-power relay with power contacts, 3 changeover contacts, coil voltage: 24 V DC

Notes on operation The outputs are not suitable for switching different outer conductors.
Notes on operation Do not use to separate SELV / PELV circuits from other circuits, because safe isolation is not guaranteed.
