Symbols

Symbols

Contactor

A contactor uses an operating mechanism to switch its main contacts and may include auxiliary contacts for control or indication. On a power drawing it represents the main switching path; on a schematic its coil and contacts may be distributed and connected by identifiers.

Drawing use: SLD / Schematic
Application: Control circuits
Reference family: IEC / IEEE / ANSI

A distinction that matters

A contactor and circuit breaker have different duties. Adding an overload relay does not make every contactor assembly equivalent to a circuit breaker.
