Which breaker protects Electric Wall Heater 3 according to the Veterinary Center prints?

The use of a two-pole 25 ampere breaker for Electric Wall Heater 3 is appropriate based on factors such as the heater's voltage requirements and the necessary current carrying capacity. Electric wall heaters are typically designed to operate at higher voltages, often 240V, which is best suited for two-pole breakers that will effectively supply the required power.

Using a 25 ampere breaker further ensures that the heater receives sufficient current without exceeding the limits that could lead to tripping under normal operating conditions. This choice aligns with the standard practice of providing ample protection for electrical heating appliances, protecting against overloads and potential hazards.

In contrast, single-pole breakers may not be able to handle the heater's demand properly, and a three-pole breaker would be unnecessarily complex and oversized for standard electric wall heater applications.
