Datasheet - J7TKN-B-4

Omron J7TKN Series Overload Relay, 2.7 to 4A Adjustable Current Range, 690V Contact Voltage - J7TKN-B-4

This overload relay provides thermal protection for motors in industrial control systems, preventing damage from sustained overcurrent and phase imbalance while operating within standard control environments. It is designed for direct mounting with selectable reset modes and accepts a 24V control signal for tripping coordination. The unit meets recognised electrical device standards and is suitable for integration into switchgear and motor starter assemblies.

Features and Benefits:

• Adjustable trip range 2.7–4A allows precise motor protection
• Dual auxiliary contacts supply signalling and interlock capability
• Resettable automatically or manually for flexible restart control
• Rated for 690V systems to support high-voltage installations
• Relay contact current 4A supports auxiliary control circuits
• Conforms to IEC 60947-4-1 standards for industry compatibility

Applications

• Suitable for protecting small three-phase motors up to 15kW
• Ideal for use in contactor-based motor starter panels
• Used with PLCs and control relays requiring 24V control inputs
• Can be used for retrofit protection in factory automation systems

What ambient temperatures can it tolerate in plant installations?

It operates between -25°C and 60°C, allowing use in cold stores and warm plant rooms without additional enclosures.

How is it mounted within a control enclosure?

The unit is designed for direct mounting onto contactor assemblies or mounting plates to simplify panel assembly and save space.

What approvals support integration into compliant electrical equipment?

It carries recognised approvals including UL and VDE along with EN/IEC 60947-4-1, facilitating use in standardised installations.

How does the device handle motor full-load conditions?

It is rated for motor currents within 2.7 to 4A and a power-handling capability up to 15kW, enabling protection of motors at those load levels.
