General Electrics TEC36003 - 3 A, 3-Pole Circuit Breaker | AmpState

Meet the General Electrics TEC36003 — a 3 A, 3-pole molded-case circuit breaker built for dependable branch circuit overcurrent and short-circuit protection in panelboards and load centers. Designed for reliability in real-world electrical layouts, this unit blends compact design with precise protection for peace of mind across residential, commercial, and light industrial environments.

Why this 3-pole breaker stands out

• Space-efficient molded-case design: a compact footprint that maximizes panel space, making it easier to fit into crowded panels without compromising performance.
• Thermal-magnetic trip unit: combines thermal (long-time) protection with magnetic (instantaneous) response for stable, repeatable protection across varying temperatures and fault currents.
• OEM-compatible: precision-built to integrate with matching General Electrics OEM load centers and panelboards, reducing installation headaches and ensuring reliable coordination within your electrical system.
• Versatile across applications: suitable for residential feeders, light commercial circuits, and basic industrial control panels that require dependable three-pole protection.

Technical snapshot

• Manufacturer: General Electrics
• Part Number: TEC36003
• Type: Thermal-magnetic molded case circuit breaker
• Amperage Rating: 3 A

Ideal use cases and practical scenarios

In a multi-circuit panelboard serving a small office or workshop, the TEC36003 provides reliable protection for essential three-phase or multi-wire circuits. It’s well-suited for lighting, receptacle banks, and small equipment feeders where a precise 3 A protection level helps prevent nuisance trips while safeguarding downstream gear. For installers upgrading or retrofitting panels, its compact form and OEM compatibility simplify the process, reducing downtime and compatibility concerns.

How this compares to typical alternatives

Compared to bulkier or less-coordinated options, the TEC36003 delivers targeted, predictable protection in a compact package. The thermal-magnetic trip unit ensures balanced response across ambient temperature changes and fault conditions, helping prevent unnecessary trips while still delivering fast action on real faults. Its alignment with OEM panelboards minimizes the risk of fitment or coordination issues during replacement or expansion projects.

Tips for selection and installation

• Verify panel compatibility by matching the part number TEC36003 with your General Electrics panel specification.
• Use in panels designed for 3-pole, 3 A protection to ensure proper trip coordination and safe operation.
• Plan for future expansion: if you anticipate higher load growth, consider evaluating higher-amperage or differently configured breakers in the same family to maintain system protection consistency.

Equip your panel with a trusted, space-conscious solution. The TEC36003 from General Electrics delivered through AmpState brings reliable overcurrent and short-circuit protection to residential, commercial, and light industrial electrical systems.
