FAQ

What size fuse should I use to replace the 333F?

The 333F is a 120‑volt, metal, through‑hole fuse with a standard physical size that fits most Rheem and compatible panels. When replacing it, select a fuse with the same amperage rating and voltage specification to maintain circuit protection integrity.

Can this fuse be used in commercial applications?

While the 333F is primarily marketed for residential use, it can be employed in light commercial settings where the circuit voltage does not exceed 120 V and the load requirements fall within the fuse’s amperage rating. Always verify local code requirements before installation.

How do I know if the fuse has failed?

A failed fuse typically shows a broken metal strip or a visible gap in the internal element. Additionally, the circuit it protects will lose power, and a multimeter can confirm an open circuit condition. Replace the fuse promptly to restore protection.

Is there a warranty on the Rheem Fuse Link 333F?

Rheem provides a limited warranty that covers manufacturing defects for a specified period from the date of purchase. For detailed warranty terms, consult the product documentation or contact Rheem customer service.

Do I need any special tools to install this fuse?

No special tools are required. The through‑hole design allows you to insert the fuse directly into the panel slot using standard hand pressure. Ensure the power is turned off before handling any electrical components.
