What is BS EN IEC 61643‑341 about ?
BS EN IEC 61643‑341 is the 341st component for low-voltage surge protection in multi-series.
BS EN IEC 61643‑341 specifies standard test circuits and methods for thyristor surge suppressor (TSS) components. These surge protective components, SPCs, are specially formulated thyristors designed to limit overvoltage and divert surge currents by clamping and switching actions. These SPCs are used in the construction of surge protective devices (SPDs) and equipment used in Information & Communications Technologies (ICT) networks with voltages up to AC 1 000 V and DC 1 500 V.
Note: BS EN IEC 61643‑341 is applicable to gated or non-gated TSS components with third quadrant (-v and –i) characteristics of blocking, conducting or switching.
Note: BS EN IEC 61643‑341 contains information on:
- Terminology
- Letter symbols
- Essential ratings and characteristics
- Rating verification and characteristic measurement
Note: BS EN IEC 61643‑341 does not apply to the conventional three-terminal thyristors as covered by IEC 60747-6.
