Omron J7TKN Series Thermal Overload Relay, 0.8 to 1.2A Adjustable Current Range, 690V Contact Voltage - J7TKN-B-1E2


This thermal overload relay provides motor protection by sensing overload conditions and interrupting supply in three-phase systems. Designed for direct mounting, it is intended for control panels and motor starters where adjustable current tripping and selectable reset modes are required. The device operates across a wide ambient temperature span and is compatible with industrial control voltages up to 690 V.

Features and Benefits:


• Adjustable trip range 0.8–1.2A gives precise motor protection
• Dual reset modes — automatic and manual — aid flexible recovery
• 3P configuration supports balanced three-phase protection
• Two auxiliary contacts, 1 NO and 1 NC, enable control signalling
• Rated to handle motor loads up to 44.301 kW for heavy-duty applications
• Conforms to EN/IEC 60947-4-1 and related standards for interoperability

Applications


• Suitable for motor starters in industrial automation racks
• Ideal for protection of small three-phase motors in production lines
• Used with contactors where direct-mount installation is required
• Can be used for plant equipment with 690V control supplies

What ambient temperatures can it tolerate during operation?


It operates reliably between −25 °C and 60 °C, covering typical indoor industrial environments.

How does the unit signal auxiliary control circuits?


It provides two auxiliary contacts arranged as one normally open and one normally closed for interlock and alarm circuits.

What mounting arrangement is required for installation?


It is designed for direct mounting onto compatible contactors or mounting plates without separate adaptor hardware.

Which safety and industry standards does it meet?


It is compliant with EN/IEC 60947-4-1, IEC 60947-4-1, VDE 0660 and listed to relevant UL requirements.
