The connectors of this family are the main products in our range, designed to meet the most demanding market requirements. They are mainly used for power supply and speed control of circulation pumps in the HVAC field but are also used in other markets that require reliable, high-performance solutions.

Alongside our historic models, such as the PUP series and similar and for PWM the PWFL and PWFA series. In recent years we have seen the success of connections derived from the Superseal and Mini-Superseal series. These belong to the UPL/UPA and PWSL/PWSA series, which have been internally redesigned by LTE, not only preserving but significantly improving their original technical features.

To further expand our offering, we have introduced a specific series distinguished by the ground contact in central position and the characteristic external grey colour. This series is suitable for circulator pumps from the Chinese brand Shinhoo.

All materials used in the production of our connectors are carefully selected and comply with the latest industry standards, ensuring quality, safety, and reliability.
