Omron, J7TKN Thermal Overload Relay, 4A, 6 A F.L.C, 6A Contact Rating, 15 kW, 690V 3P

This thermal overload relay provides motor protection by sensing overcurrent and interrupting supply to prevent thermal damage in three-phase systems. It is designed for direct mounting and offers adjustable current settings to match motor full-load conditions, making it suitable for control panels and industrial motor starters where compact, temperature-tolerant thermal protection is required.

• Adjustable current range 4 to 6A enables precise motor protection matching
• Trip current rating 6A prevents sustained overloads on connected motors
• Control voltage 690V allows use in high-voltage control circuits
• Power capacity 15 kW supports medium-duty motor applications
• Reset selectable automatic and manual for operational flexibility
• Compliance with IEC 60947-4-1 standards ensures recognised industrial interoperability

• Suitable for protecting three-phase motors in automated plant
• Ideal for use with contactors in motor starter assemblies
• Used for safeguarding conveyor drive motors up to 15 kW
• Can be used for control cabinets in manufacturing equipment
• Used with distribution panels requiring Compact thermal protection

It is rated to operate between -25 °C and 60 °C, enabling use in cold storage to warm plant environments.

The device is designed for direct mounting, allowing it to be fitted immediately alongside contactors without additional adaptors.

It employs a three-pole arrangement providing simultaneous protection across all three phases.

Allowance should be MADE for a width of 45mm and a length of 126.5mm when planning component spacing.
