Practical Notes
- Interrupting capability is 1,000 A at 32 Vac — confirm the circuit's prospective fault current stays below this.
- Time-delay element rides through motor starting and capacitive inrush without nuisance opening.
- Startup surges of several times rated current are tolerated for a short window.
- Glass body lets you inspect the element after a fault.
- Best kept for lower fault-current circuits where visual diagnosis matters.
- Working voltage must stay at or below 32 Vac; a lower-rated part is not a safe substitute.
- Do not upsize beyond 20 A to stop nuisance trips — fix the cause instead.
Application Scenarios
Common installation contexts include:
- EV
- transformer
Questions and Answers
What are the ratings of the MDL-20-R?
20 A continuous at 32 Vac, interrupting rating 1,000 A at 32 Vac.
Is the MDL-20-R fast-acting or time-delay?
It is time-delay. It tolerates short inrush surges.
Can the MDL-20-R be used on a higher fault-current circuit?
No — its interrupting rating is 1,000 A at 32 Vac. Choose a part whose breaking capacity exceeds the prospective fault current.
