Type 1 and Type 2 coordination are crucial for ensuring the safety and reliability of electrical installations by defining how protective devices like circuit breakers and contactors behave under fault conditions.

• Type 1 Coordination: Ensures that under short-circuit conditions, the device (e.g., contactor or starter) does not cause danger to persons or installation and may not be suitable for further service without repair or replacement of parts.
• Type 2 Coordination: Ensures that under short-circuit conditions, the device (e.g., contactor or starter) shall cause no danger to persons or installation and shall be suitable for further use. The risk of contact welding is recognized and manufacturers should state measures to be taken in regard to the maintenance of the equipment.

Below is a placeholder for where coordination charts (e.g., from manufacturer datasheets like Schneider Electric, Siemens, ABB, Legrand) would typically be displayed or linked. These charts detail specific combinations of breakers, contactors, and overload relays that achieve Type 1 or Type 2 coordination.

Note: Always refer to the latest manufacturer documentation for specific product combinations and coordination details. The information provided here is for general understanding only.
