This document provides detailed information on the characteristics of Raychem Circuit Protection PolySwitch products, including the working principle and application scenarios
The PolySwitch® resettable device short‑form catalog presents Tyco Electronics’ (Raychem Circuit Protection) PPTC products. It describes the technology, benefits, and a wide range of applications such as automotive, battery protection, computers, industrial equipment and telecommunications.
The document lists numerous series (e.g., LVR, RXEF, RTEF, RUEF, RHEF, RGEF, RUSBF) with their electrical ratings, form factors and compliance (ELV, RoHS, UL, TUV, CSA). Definitions of key parameters (Imax, Vmax, Rymax, etc.) and voltage rating notes for telecom devices are also included.
| Hold current @ 25°C | varies by series |
|---|---|
| ELV Compliant | Yes |
| Maximum line voltage (LVR series) | 120 Vac to 240 Vac |
| RoHS Compliant (various series) | Yes |
ELV compliance indicates the device meets Extra‑Low Voltage safety standards, allowing use in low‑voltage applications while still providing protection.
