About the Marley 4520-0011-000

The Marley 4520-0011-000 is a genuine replacement high limit for Marley, Qmark and Berko electric heaters. It is an automatic-reset safety limit that opens the heating circuit when internal temperature passes 300°F, then resets on its own once the heater cools.

It is a linear-style limit with a copper sensing element. Check your heater's model number against the compatible-models list on this page before ordering.

Turn off power at the breaker before opening the heater.
