Settings on the 3RA61/3RA62 compact starter
All settings are made on the 3RA61/3RA62 compact starter itself.
CLASS 10E / 20E
The CLASS (overload trip class) indicates the tripping time t
A
of the compact starter (from

. As the compact starter has the functionality of a solid-
state overload relay, the trip class corresponds to the narrow tolerance band E
(IEC / EN 60947-6-2):
●
CLASS 10E: 5 s < t
A
< 10 s
●
CLASS 20E: 10 s < t

< 20 s (for heavy starting)
You can use a slide switch to set the trip class to CLASS 10E or CLASS 20E.
