Omron J7TKN Series Thermal Overload Relay, 1.2-1.8A Adjustable Current Range, 15kW Power Rating - J7TKN-B-1E8
This thermal overload relay provides thermal protection for three-phase motors by sensing motor current and interrupting circuits when overloads occur. It is designed for direct mounting in control panels and motor starters, offering automatic resetting to restore operation after thermal conditions normalise. The relay supports high-voltage systems and is suitable for installations requiring standardised electrotechnical performance.
Features and Benefits:
• Adjustable trip setting 1.2-1.8A for tailored motor protection
• Three-pole configuration enabling balanced phase sensing
• Rated for 690V supply to suit high-voltage systems
• 15kW power rating allowing protection of medium-power motors
• Automatic reset method for unattended restart after cool-down
• Relay contact current 600mA compatible with auxiliary circuits
• Three-pole configuration enabling balanced phase sensing
• Rated for 690V supply to suit high-voltage systems
• 15kW power rating allowing protection of medium-power motors
• Automatic reset method for unattended restart after cool-down
• Relay contact current 600mA compatible with auxiliary circuits
Applications
• Suitable for incorporation into motor starter assemblies for industrial drives
• Ideal for protecting small three-phase motors rated 0.4A and 0.6A
• Used with automation panels requiring IEC-standard protective devices
• Can be used for overload protection in manufacturing plant control cabinets
• Ideal for protecting small three-phase motors rated 0.4A and 0.6A
• Used with automation panels requiring IEC-standard protective devices

What ambient temperatures can it tolerate in typical plant environments?
It operates between -25°C and 60°C, covering cold storage spaces and warm electrical rooms without derating beyond those limits.
How does mounting affect installation flexibility?
The direct-mount configuration permits straightforward attachment to compatible contactors and mounting plates, reducing additional bracketry.
What approvals and standards does it meet for industrial use?
It conforms to IEC 60947-4-1 and EN 60947-4-1 and carries relevant national approvals listed under its specification set.
What electrical supply and contact ratings are relevant for system design?
Design should account for a 690V supply rating and 600mA auxiliary contact current when planning control circuitry.
What are the physical envelope considerations for panel layout?
The unit occupies a Compact footprint of width 45mm and length 126.5mm, with depth 70mm to assist precise space allocation.
