Circuit Breaker LTL Shipping Guide
Freight Class for Circuit Breaker
To estimate your shipment, use the Circuit Breaker Freight Class Calculator.
The Circuit Breaker Freight Class Examples use the current 13-tier density scale, effective July 19, 2025, and range from Class 70–100.
These are density-based estimates.

Circuit Breaker shipment comparison
Circuit Breaker Freight Class by Shipment Format
Circuit Breaker freight class can change with finished packaging, density, weight distribution, protective clearance, and stackability. Use the finished packaged dimensions and total weight rather than the unpackaged product size.
| Circuit Breaker shipment | Typical packaging | Density tendency | Stackability | Planning note |
|---|---|---|---|---|
| Cartoned molded-case breakers | Multiple breaker cartons on a pallet | Moderate | Stackable | Separate handles and accessories and protect trip units from impact. This example calculates to 18.00 lb/cu ft and Class 70. |
| Mixed breaker pallet | Palletized breaker cartons and hardware | Moderate | Stackable | Band cartons tightly and avoid crushing electronic trip units. This example calculates to 21.50 lb/cu ft and Class 70. |
| Large draw-out breaker | Single breaker in a protective crate | Medium to lower | Non-stackable | Immobilize the draw-out carriage and protect primary contacts and controls. This example calculates to 9.38 lb/cu ft and Class 100. |
| Multi-piece or accessory shipment | Main circuit breaker package plus separately protected components, accessories, or mounting hardware | Varies | Confirm each piece | List every separate piece and include its finished dimensions, weight, packaging, and stackability in the quote request. |
Circuit Breaker shipping options
How Shipping Method Affects Circuit Breaker Freight Class
The appropriate service depends on finished dimensions, packaged weight, piece count, loading method, value, stackability, and whether specialized handling is required.
| Circuit Breaker shipment | Common shipping option |
|---|---|
| Cartoned molded-case breakers | Parcel or LTL, depending on carton count, value, and handling requirements |
| Mixed breaker pallet | LTL with packaging, stackability, and handling review |
| Large draw-out breaker | LTL with packaging, stackability, and handling review |
| Multi-piece, high-value, or special-handling shipment | LTL, volume, partial truckload, dedicated, or specialized service after piece-count and handling review |
Small units may move by parcel; pallets and draw-out breakers usually move by LTL.
Circuit Breaker Packaging, Stackability, and Damage Risk
Circuit Breaker Packaging
- Contact protection, cushioned crates, accessory separation, and moisture control.
- Separate handles and accessories and protect trip units from impact.
- Band cartons tightly and avoid crushing electronic trip units.
Circuit Breaker Stackability
- Stackable when cartons and pallet are stable.
- Usually stackable with a flat, reinforced top.
- Non-stackable unless the crate is engineered.
Circuit Breaker Fragility and Liability
- Damaged contacts, cracked housings, shifted mechanisms, and electronic trip-unit damage.
- Immobilize the draw-out carriage and protect primary contacts and controls.
- Confirm declared value, coverage, orientation, and any top-load or special-handling restrictions before tendering circuit breaker freight.
Before Requesting a Circuit Breaker Freight Quote
How to Measure a Packaged Circuit Breaker Shipment
- Measure after the circuit breaker is secured and all cartons, pallets, skids, crates, framing, and protective materials are complete.
- Include runners, legs, reels, doors, fittings, cables, brackets, accessories, overhang, and every projecting packaged component that applies.
- Measure to the longest, widest, and tallest finished point and use the total tendered shipment weight.
Circuit Breaker Freight Quote Checklist
- Record the finished packaged length, width, height, quantity, and total weight.
- State whether the shipment is stackable and whether top loading or side loading is restricted.
- Include photos showing packaging, securement, labels, lift points, and exposed risk areas when practical.
- Describe the exact circuit breaker shipment format and list detached components, accessories, cables, mounting hardware, or separate pieces.
- Confirm forklift, dock, liftgate, crane, rigging, inside-delivery, or specialized loading requirements.
