    Practical Notes

    • Interrupting capability is 35–63 A @ 250 VAC (rating-dependent); 50 A @ 125 VDC — confirm the circuit's prospective fault current stays below this.
    • Working voltage must stay at or below 250 VAC; a lower-rated part is not a safe substitute.
    • Do not upsize beyond 2 A to stop nuisance trips — fix the cause instead.

    Application Scenarios

    Common installation contexts include:

    • battery
    • EV
    • charger

    Buying Notes

    Order code 37212000001 from Littelfuse, supplied in TR5® radial lead fuse; Long leads; Tape & Ammopack. Confirm the exact suffix before release.

    Questions and Answers

    What are the ratings of the 37212000001?

    2 A continuous at 250 VAC, interrupting rating 35–63 A @ 250 VAC (rating-dependent); 50 A @ 125 VDC.

    Can the 37212000001 be used on a higher fault-current circuit?

    No — its interrupting rating is 35–63 A @ 250 VAC (rating-dependent); 50 A @ 125 VDC. Choose a part whose breaking capacity exceeds the prospective fault current.
