The GEDTJK436T400 is a GE 3-pole trip unit rated at 400A and 600V, designed for optimal performance in industrial and commercial applications. This reliable trip unit provides enhanced protection for your electrical systems by detecting and preventing overloads. Ideal for various setups, ensuring safety and efficiency in your operations.
Trip unit replacement on molded-case circuit breakers like the GE TJK frame must be performed by a qualified electrician in accordance with the Canadian Electrical Code (CEC). Improper installation can void equipment ratings and create serious safety hazards. Always de-energize and follow proper lockout/tagout procedures before any work.
GE's TJK-frame product line is considered a legacy/discontinued series. Northern Breaker Group specializes in sourcing obsolete and hard-to-find GE breaker components — contact our Calgary, Edmonton, or Vancouver counter for current stock availability and lead times on this trip unit.
Trip units are frame- and series-specific, and re-rating a breaker using a different trip unit must only be done within the manufacturer's approved rating range for that frame. The TJK frame supports specific plug-in or interchangeable trip unit ratings — we strongly recommend confirming the original breaker's catalogue number with us before ordering to ensure the 400A rating is within the approved range for your unit.
