Relays are typically used to control inductive loads up to what maximum amperage?

Relays are commonly designed to control inductive loads, such as motors and transformers, and they often handle current in a range of 10 amps. The significance of this amperage is tied to the relay's ability to effectively manage the additional electrical stress that inductive loads create, such as inrush current, without overheating or sustaining damage.

While relays can occasionally be rated for higher amperage, 10 amps is a standard maximum rating for many common relays. This number balances the relay's thermal characteristics, contacts’ physical size, and the materials used in construction, ensuring reliable operation while preventing premature failure. Therefore, selecting a relay with a maximum rating of 10 amps for controlling inductive loads is both practical and widely accepted in the field.

Higher amperage choices may indicate designs more suitable for switches or contactors rather than standard relays. This knowledge aligns with best practices in HVAC systems, where proper component selection is critical for system reliability and performance.
