SPT series large wire diameter in-line spring connectors: safe and reliable high-current connection

Create Date: 2024-8-30 12:03:23|Source: Phoenix Contact/Phoenix

Continuously achieving more powerful equipment power and wider redundant dynamic performance is the development trend of industrial applications such as UPS, servo drives, and industrial inverters, and it is also an important requirement for current inverter & rectification in photovoltaic and energy storage systems in the rapidly developing industry.

While the performance of high-current and high-voltage transmission is improved, engineers also need to consider how to effectively control the temperature rise of the connection in high-load applications to ensure the operation safety of the equipment.

In addition to signal and data connection solutions, the SPT series offers reliable wiring solutions for power transmission in the SPT 5-35 series, with a maximum current carrying capacity of 125 A, a rated voltage of 1000 V, and a maximum withstand voltage of 1500 V with the addition of a separator.

Product Information
SPT series large wire diameter in-line spring connectors: safe and reliable high-current connection
Product Advantages:

Winner of the 2023 Stevie Gold Prize, Germany Innovation Award

1. High-quality materials, high-current safe connection

SPT series products are made of high-quality copper alloy self-made current strips, as well as exclusive plating technology, which gives excellent contact resistance to the electrical connection and effectively ensures that the temperature rise of high-current load wiring is within the controllable safety range. The plastic material used in the housing has a UL-94 V0 flame retardant rating, which can withstand high temperature applications and the connection structure remains stable and reliable.

2. In-line spring connection, tool-free wiring

The Push-in spring technology used does not require tools to operate during the wiring process, which not only improves the wiring efficiency, but also reduces the operation steps of the wiring personnel and reduces the hidden dangers of non-standard operations. The high-quality spring parts can still maintain a reliable connection between the wire and the current bar after long-term use.

3. Strict standards, high quality and assured selection

Whether it's the rigorous electrical, mechanical, and environmental tests that take into account the different application environments during the testing phase, or the high-precision mold injection, finishing, and automated assembly in the production process, Phoenix Contact is committed to product quality and customer experience.

Application scenarios

With the above-mentioned characteristics and advantages of controllable temperature rise at high loads, reliable and efficient wiring, the SPT 5-35 series products are mainly used in power connection in equipment transmission, especially for the following equipment:
SPT series large wire diameter in-line spring connectors: safe and reliable high-current connection
