FAQ

1: What size fuse does R3‑63 accept?

A: It matches 6.35×31.75 mm standard cartridge fuses. Notably, operating current must stay within 10‑30A range and voltage not exceed 600V AC/DC.

2: Can I change wire gauge or wire length?

A: Yes. Custom wire configurations can be done as special order. Please send your exact requirements to our sales team.

3: Why should I adjust wire specification?

A: Wire selection depends on real working current and wire length, preventing over‑heating risk for long‑term running circuits.

4: What is the flame rating of R3‑63 base?

A: The bakelite base complies with UL‑94V‑0 flame‑retardant standard for higher‑safety industrial usage.
