Instructionsheet - J7TKN-B-18

Omron J7TKN Series Thermal Overload Relay, 13 to 18A Adjustable Current Range, 690V Control Voltage - J7TKN-B-18

This thermal overload relay provides adjustable protection for three-phase motors by sensing current and interrupting circuits when overload conditions occur. Designed for direct mounting in industrial control panels, it supports motor protection up to the specified power rating and operates across a wide ambient temperature range to suit varied plant environments.

Features and Benefits:

• Adjustable 13–18A range protects motors across multiple ratings
• 1NO/1NC contact arrangement enables signalling and control switching
• 2P configuration facilitates Compact two-pole interruption
• Automatic and manual reset options allow flexible restart strategies
• Rated for control and contact voltages up to 690V for high-voltage systems
• Conforms to IEC/EN and national standards for recognised compatibility

Applications

• Suitable for protecting industrial motors with 10A full-load current
• Ideal for control panels in machinery using 690V supplies
• Used with power trains requiring thermal protection for up to 44.301 kW motors
• Can be used as a replacement for direct-mounted overloads in automation racks

What ambient temperatures can it tolerate during operation?

It operates reliably between −25 °C and 60 °C, allowing use in cold storerooms and heated plant rooms.

How does the relay signal motor trip and normal conditions?

It provides one normally open and one normally closed contact to deliver both alarm and interlock functions.

What mounting method is required for installation?

The unit is intended for direct mounting, enabling straightforward attachment to contactors or mounting rails.

Which standards ensure compatibility with industrial control gear?

It meets EN/IEC 60947-4-1 and IEC 60947-4-1 and holds approvals including UL and VDE 0660.
