TE Connectivity TRSA Heat Shrink Cable Marker, White, Pre-printed '3', Polyolefin, 6 mm Max Cable, 2 mm Min TRSA-1019/E/1/3

TE Connectivity's TRSA-1019/E/1/3 Heat Shrink Cable Marker is engineered for cable management applications across electrical, automation and industrial settings, offering clear and permanent cable identification.

This heat-shrinkable marker comes pre-printed with the legend ‘3’ in black on a white background for high visibility, even under poor lighting conditions. Manufactured from polyolefin, the marker ensures exceptional flame retardancy and mechanical durability. Designed for cable diameters between 2 mm and 6 mm, the marker shrinks to 33% of its supplied diameter when heated over 120°C, providing a secure fit around various cable types.

The continuous temperature range of -55°C to +135°C, and short-term resistance up to 300°C, enables use in demanding environments such as industrial, laboratory and commercial installations. The 3:1 shrink ratio allows for flexible application, making installation quick and efficient. The polyolefin material offers good resistance to common fluids and chemicals, extending the marker's service life.

Compliance with ASTM D876, ISO 37, IEC 243, ISO 1817 and ISO 188 standards supports quality assurance. The marker’s tensile strength of 5 MPa adds robustness for long-term cable management. Flame retardancy per ASTM D876 ensures enhanced safety; burning duration is limited to a maximum of 30 seconds.

TE Connectivity's TRSA series markers are widely used in environments where reliable cable identification and secure cable marking are essential, from control panels and switchboards to manufacturing plants and HVAC systems. The marker is printable (No) and features white color for universal marking compatibility.

Pre-printed legend provides ready-to-use identification for cables. Heat-shrinkable polyolefin construction delivers lasting performance and improved fire safety. Wide operating temperature range suits diverse industrial applications.

Resistance to fluids and chemicals ensures longevity under harsh conditions. Install easily and rapidly using standard heat tools for cable management solutions.
