Class/Max Amp Rating
• Short Circuit Current Rating investigated in 16 x 12 x 6 enclosure. Use in smaller enclosure is
subject to end-use evaluation.
Mechanical Ratings:
• Maximum insulator base and cover temperature: 125°C (257°F) UL RTI
• Flammability rating of insulator base and cover: UL 94 V-0
* Use outside these ratings needs to be judged in the end-use application.
