Burndy Crimper Buying Guide
Compare Burndy crimpers: 6-ton vs 12-ton, T3 intelligence, and head styles.
Burndy Crimper Buying Guide
When evaluating power crimping and swaging tools for commercial, industrial, or utility electrical projects, professionals Burndy is a commonly-sought brand. Known for the PATRIOT® line of battery-actuated tools, Burndy focuses on a system-based approach to electrical connectivity. This buying guide explores the technical features, innovative technologies, and model-specific differences essential for buyers to understand before making an investment.
The Burndy Engineered System
A critical concept for any buyer is the "Burndy Engineered System." This refers to the synergy between the connector, the conductor, and the installation tool. Burndy tools are designed and tested to work specifically with Burndy connectors to meet UL listing and CSA certification requirements. Using non-compatible dies or tools can compromise the integrity of the connection and may lead to code compliance failures.

Key Technical Features for Commercial Buyers
1. Crimping Force (Tonnage)
The "tonnage" of a tool defines its mechanical capacity. Choosing the correct force ensures that the connector is sufficiently compressed to create a gas-tight, permanent connection.
- 15-Ton & 12-Ton: These are the primary choices for heavy industrial applications, substations, and large-scale commercial builds. They handle massive conductors up to 1500 kcmil.
- 11-Ton: Often seen in "dieless" configurations, these offer high capacity with the flexibility of range-taking nests.
- 6-Ton: The industry standard for service entrance work and medium-voltage distribution.
- 2-Ton: Specialized for smaller terminals and tight-access applications.
2. Head Geometry and Accessibility
Head design dictates the tool's versatility in cramped spaces:
- C-Head (Open Head): Features a permanent opening that allows the tool to easily hook over a continuous conductor without needing to open a latch.
- Latch Head (Flip Top): Securely locks around the connector. It is often preferred for high-tension applications where the tool must remain perfectly centered.
- Scissor/In-line Head: Features a slim profile for one-handed operation in tight enclosures or overhead work.
3. Battery Platform: Makita 18V LXT
Burndy has standardized its power tool line on the Makita 18V Lithium-Ion (LXT) battery platform. This is a significant advantage for commercial shops already using Makita cordless tools, as batteries and chargers are interchangeable. Most kits include high-capacity batteries (3.0Ah or 5.0Ah) to provide hundreds of crimps per charge.
4. Advanced Tool Intelligence (T3 Technology)
Modern Burndy tools, designated by the "T3" suffix, feature Track-Trace-Transmit technology. This is an essential feature for large-scale projects requiring documented quality control:
- Track: Onboard GPS records the location of every crimp.
- Trace: The tool monitors output force and cycle completion, alerting the user with an LED indicator (Green for pass, Red for fail).
Transmit: Data is synced via Bluetooth to the cloud, allowing project managers to generate reports proving every connection on the job site meets specifications.
Technical Maintenance and Field Usage
When researching burndy hydraulic crimpers, buyers should be aware of the operational features that ensure longevity and safety.
Infinity Drive® Transmission
Many tools in the Patriot series feature the Infinity Drive transmission. This is a refined hydraulic pump system that increases speed and reliability. Burndy offers a lifetime warranty on this specific component in many of its power tools, reflecting the durability expected in a commercial setting.
Audible Pop-Off Valve
A common question among operators is "How do I know the crimp is complete?" Burndy tools feature an audible "pop-off" pressure relief valve. When the tool reaches its rated tonnage (e.g., 12 tons for a PAT750), the valve releases, creating a distinct sound that signifies the full compression has been reached. This prevents over-crimping and ensures the electrical connection is consistent with the UL-listed design.
