What it represents
A thermal overload relay monitors motor-circuit loading and operates associated control contacts.
Account for direct attachment to a contactor or a separate mounting adapter. The GA locates the physical item; the associated schematic or equipment schedule records its electrical interfaces.
The preview is independent educational geometry and is not a manufacturer outline, fabrication drawing or verified standard graphic. Obtain the applicable model drawing from the cited official source before making a dimensional layout.
How to read it
- Account for direct attachment to a contactor or a separate mounting adapter.
- An overload relay is not a short-circuit interruption device.
Information to show or reference
- Confirm the exact equipment identity, drawing revision and installation orientation.
- Account for direct attachment to a contactor or a separate mounting adapter.
- Cross-reference the terminals, cable routes and service tasks with the equipment schedule.
A distinction that matters
An overload relay is not a short-circuit interruption device.
