Amphe-GTR: Power Distribution Systems for High-Current Industrial Applications
Power distribution systems are the backbone of today’s electrified technologies, and Amphenol Industrial Operations delivers with the Amphe-GTR connector series. This rugged single-pole connector is engineered for high voltage, high current applications in EVs, renewable energy, data centers, and industrial automation. Amphe-GTR offers an efficient, field-installable solution that ensures reliability, flexibility, and long-term performance in challenging environments.
Amphe-GTR is a compact, high-performance solution built for modern power distribution systems. Featuring push-turn locking, IP67 protection, and compatibility with cables up to 120 mm², the connector enables secure high-current connections with minimal effort. It’s the preferred choice for OEMs and integrators needing scalable connectivity for both mobile and stationary systems.
High-Power, Field-Installable Interface
The Amphe-GTR connector supports current ratings up to 350A and voltages up to 1000V DC, making it ideal for critical system links within power distribution systems. Designed with a tool-less locking mechanism, this connector minimizes installation time while maximizing connection integrity in the field. Options for straight and 90° backshells, multiple terminations, and sealing accessories provide flexible deployment in compact or sealed enclosures.
Durability for Harsh Operating Conditions
Built to withstand industrial abuse, Amphe-GTR offers IP67-rated ingress protection when mated and uses thermoplastic UL94-V0 materials for fire resistance. Its robust housing resists impact and vibration, while integrated sealing options protect against dust and moisture in rugged field environments.
The heart of the Amphe-GTR’s performance lies in its RADSOK® technology—Amphenol’s twisted-grid contact system that improves current density, reduces resistance, and enhances thermal management. This makes it well-suited for demanding power distribution systems where efficiency and safety are critical.
Versatility Across Industries
Used in electric vehicles, heavy-duty transportation, energy storage systems, and industrial automation, Amphe-GTR fits a variety of power distribution systems. In EVs, it links battery packs and inverters. In ESS platforms, it ensures stable interconnection between racks and converters. It’s also used in backup power units for data centers and in charging stations for electrified fleets.
Its single-pole design supports scalable configurations, whether in series for large-scale systems or in compact setups for confined enclosures. The connector’s ease of use and flexibility make it an ideal candidate for standardization across platforms.
Safety and Compliance
Amphe-GTR connectors are engineered to meet IEC 60529 safety guidelines, with touch-proof interfaces, HVIL (High Voltage Interlock Loop) options, and secure mating that resists accidental disconnection. Industry approvals like UL and IEC ensure global acceptance and compliance in regulated applications.
Engineers can tailor the connector with color-coded housings, keying options, and shielding add-ons to meet mechanical and EMC needs, ensuring a clean integration into their system’s design.
Streamlined System Integration
Available in panel mount or inline versions, Amphe-GTR is built to adapt to various architectures. Supported terminations include crimp, bolt, and busbar—accommodating cable flexibility and space-saving designs. Its low contact resistance and rugged locking design make it ideal for repeated use in field-serviceable or modular systems.
When designing future-ready power distribution systems, the Amphe-GTR series offers the performance, durability, and configurability that modern engineers require.
