The following ring cable lugs are approved for achieving the required clearances and creepage distances:
● For applications according to IEC 60947-1:
– DIN 46237 (with insulating sleeve)
– JIS CS805 type RAV (with insulating sleeve)
– JIS CS805 type RAP (with insulating sleeve)
● For applications according to UL 508:
– DIN 46 234 (without insulating sleeve)
– DIN 46225 (without insulating sleeve)
– JIS CS805 (without insulating sleeve)
A shrink-on sleeve must be used to insulate ring cable lugs without an insulating sleeve. The following
conditions must be met:
● Application temperature: -55 °C to +155 °C
● UL 224 approved
● Flame-protected
DANGER
Hazardous voltage.
Will cause death or serious injury.
Only use approved ring cable lugs to meet the required clearances and creepage
distances.
