Product catalog summary

Company Overview

SETsafe and SETfuse specialize in electrical safety and protection solutions, offering a wide range of products designed to protect electrical systems from over-temperature and over-voltage conditions. Their management system and dedicated testing center ensure high-quality standards through witnessed test data programs, validating product performance and reliability.

Product Categories

1. Over-Temperature Protection

SETsafe provides diverse thermal link products based on ATCO alloy and organic materials, designed to interrupt circuits upon detecting excessive temperatures. These include numerous series for both AC and DC applications, such as F, K, KG, X, TGH, ARL, and many others. Organic-type thermal links and thermal turn-on devices are also offered to cover various protection needs.

2. Over-Voltage Protection

The company offers a comprehensive portfolio of transient voltage suppression (TVS) diodes, including standard and automotive-grade types (e.g., P6SMB, SMCJ, ASMB series). Additional over-voltage protection devices include thermal-protected TVS diodes, ESD diode arrays, thyristor surge suppressors (TSS), gas discharge tubes (GDT) in surface-mount and through-hole formats, thermally protected GDTs, and metal oxide varistors (MOVs) with various voltage and surge current ratings.

Quality and Testing

SETsafe operates a Testing Center and Laboratory supporting a Witnessed Test Data Program (WTDP), providing documented and customer- or third-party-witnessed test data to ensure product safety and performance compliance.

Management System

The company maintains a structured management system focused on quality assurance, continuous improvement, and adherence to industry standards, ensuring reliable and safe electrical protection components.

Detailed Product Overviews

Over-Voltage Protection Devices

TVS Diodes: Automotive-grade series (ASMA, ASMC, ASMD, SM5Sxx, etc.) with fast response, high surge current capability, and surface-mount packaging.
Thermal-Protected TVS Diodes: Series like TTVSxxK and TTVSxxM integrate thermal shutdown to prevent damage under sustained overload.
ESD TVS Diode Arrays: Multi-line protection arrays (e.g., GSM24CCAN, SD04A6D32G) for data and communication lines.
Thyristor Surge Suppressors (TSS): High surge current devices for AC/DC circuits, protecting power lines and industrial equipment.
Gas Discharge Tubes (GDT): Available in SMD, DIP, and high-surge types, including thermally protected variants to prevent thermal runaway.
Metal Oxide Varistors (MOVs): Wide range of standard, high surge, and lightning protection types (T1, T2), with various packaging and temperature ratings.

Over-Current Protection Devices

Miniature Fuses: Cartridge, sub-miniature, and surface-mount fuse links designed for compact and reliable circuit protection.
Fusible Wirewound and Thermal Link Fusing Resistors: Combined resistor and fuse functions for over-current and thermal protection.
