ABB TJK436400WL 3P MCCB - CORE J MCCB
Part Number: 7GSP032026R0006
Quick Summary
ABB TJK436400WL MCCB delivers reliable overcurrent protection for electrical distribution and machine panels. This 3-pole device helps keep critical HVAC and industrial equipment online by quickly interrupting fault currents. In real-world environments, undersized protection or mis-coordination leads to downtime; this model’s 600V rating and 400A capacity support safe, scalable protection for mid- to high-load circuits. While the data sheet identifies CORE J MCCB as the main type, regional certifications such as CE marking and IP ratings should be verified for each installation. The combination of robust protection with ABB engineering translates to lower maintenance costs, easier sourcing, and improved coordination with upstream devices. For panel builders and integrators, this means faster commissioning and more reliable system performance.

FAQs
The TJK436400WL is a three-pole MCCB designed for standard panel mounting in electrical cabinets. Ensure the supply side is rated for 600V and that conductors and terminations are sized for a 400A load. Follow ABB installation instructions for torque, conductor sizing, and clearances to ensure reliable protection and safe operation.
CORE J trip technology provides overload and short-circuit protection through well-defined current-time characteristics. This enables selective tripping where upstream devices can continue to feed other circuits, reducing overall downtime. In HVAC and machinery panels, it helps prevent nuisance trips while safeguarding motors and drives from hazardous faults.
Yes. With a 3P configuration, 600V rating, and 400A current capacity, the TJK436400WL is well-suited for general motor protection in HVAC equipment and related control panels. It provides fast fault interruption, helping protect motors and drives from overloads and short circuits while supporting reliable panel operation.
The product data indicates UNSPSC 39121616 and WEEE Category as not in scope. Regional standards such as CE marking and IP ratings should be confirmed with the supplier or datasheet for your specific deployment region to ensure compliance with local electrical codes and safety requirements.
Using the TJK436400WL reduces unplanned downtime by providing reliable overcurrent protection and easier fault isolation. Its robust CORE J design supports longer service life and straightforward replacement in field installations, translating to lower maintenance costs and faster recovery in critical HVAC and manufacturing applications.
