GE TKMA31000WL Advanced Industrial Power Management Module

Description

Real-World Use & Application Scenarios
Where is this product used and why?
TKMA31000WL is often selected for main or branch circuit protection in industrial facilities such as manufacturing plants, data centers, and large facilities with high-current feeders. Its 1000 A rating and 3-pole configuration make it suitable for three-phase distribution circuits feeding large motors, transformers, and heavy loads. The interchangeability within the TKMA/K1200 family allows designers to standardize protection devices across multiple panels, simplifying procurement and maintenance. The device’s ability to handle high interrupting ratings at various voltages (240/480/600 V) makes it versatile for different site electrical architectures. End users search for terms like “GE TKMA31000WL” or “MCCB 1000A 3P 600V” when evaluating protective devices for main feeders and motor control centers.

Product Introduction & Positioning
What it is, where it fits, and why it matters
The TKMA31000WL is a General Electric molded case circuit breaker designed for heavy-duty protection of three-phase feeders. It fits into standard MCCB enclosures and is compatible with bolt-on terminal configurations typical of the TKMA line. This model is part of a broader GE protection portfolio used in industrial power distribution, enabling consistent protection strategy across multiple panels. Its presence signals a need for durable interrupting capability and reliable overload protection in demanding environments, making it a practical choice for plants aiming to standardize protective devices across electrical rooms and switchgear.

Key Technical Features & Functional Benefits
Performance, reliability, and integration
Key features typically include a 1000 A current rating, three-pole arrangement, and a 600 V maximum voltage, with interrupting capacities up to 42 kA at 240 V and proportionally appropriate at higher voltages. The thermal-magnetic trip provides both instantaneous and timed protection for overloads, supporting quick isolation of faults. The TKMA31000WL offers a robust mechanical design, consistent electrical performance, and straightforward replacement in standard MTM MCCB ecosystems. Its compatibility with common termination styles and enclosure footprints helps streamline installation and maintenance in industrial power distribution schemes.

Installation Notes & Maintenance Best Practices
Two concise paragraphs
During installation, verify the exact enclosure compatibility, torque specs for mounting hardware, and correct alignment of line/load terminals to prevent connection issues. Ensure conductor sizing and lug types meet the breaker’s ratings and site standards, and confirm the breaker is properly wired into the protection scheme with appropriate shunt trip or auxiliary options if required. After installation, perform functional testing including temperature rise checks under nominal load, and verify coordination with upstream protection devices. Schedule regular maintenance to inspect terminal connections, verify insulation integrity, and confirm the breaker’s mechanical operation, replacing or refurbishing as needed to preserve reliability.
