UL AWM Style 3321 — 150°C XLPE Wire Supply for Vietnam and Indonesia
UL AWM Style 3321 is a 150°C maximum, 600 Vac / 750 Vdc extruded XLPE wire for the protected internal wiring of appliances, covering 30 AWG through 4/0 AWG with an optional treated or untreated braid covering. This page covers factory-direct supply of UL AWM Style 3321 for appliance OEMs and equipment manufacturers in Vietnam and Indonesia. CIF Ho Chi Minh City and CIF Surabaya export is available from the Yangzhou production facility. UL AWM Style 3321 documentation can be provided according to the confirmed ordered construction. For the general Style overview, specifications, and XLPE selection notes, see the UL AWM 3321 product page.
Where UL 3321 Fits in the XLPE AWM Temperature Hierarchy
Vietnamese and Indonesian appliance manufacturers selecting between XLPE AWM Styles at 600V class encounter three temperature options. The table below summarises the XLPE and silicone options within this production scope, to support selection at the equipment thermal design stage.
| Style | Insulation | Temperature | Voltage | Consider when |
|---|---|---|---|---|
| UL AWM 3666 | XLPE | 105°C max | 600 Vac | Standard 105°C internal wiring where mechanical abuse is not a concern |
| UL AWM 3271 | XLPE | 125°C max | 600 Vac / 750 Vdc | 125°C internal wiring; also covers motor lead applications |
| UL AWM 3321 (this page) | XLPE | 150°C max | 600 Vac / 750 Vdc | Internal wiring locations where 125°C XLPE is insufficient and XLPE is preferred over silicone |
| UL AWM 3071 / 3135 | Silicone rubber | 200°C max | 600 Vac | Above 150°C where silicone rubber temperature class is required |
The practical selection logic for appliance internal wiring: where the wire routing location inside the enclosed appliance operates above 125°C during sustained full-power operation, UL AWM 3271 is no longer sufficient and UL AWM 3321 becomes the XLPE option. Where the routing temperature reaches or approaches 200°C, silicone rubber AWM wire is required instead. UL AWM 3321 occupies the gap between these two thresholds, and for many Vietnamese and Indonesian appliance assembly configurations, it provides adequate thermal performance at a lower cost position than silicone rubber.

Applications — Vietnamese and Indonesian Appliance Internal Wiring
In Vietnam and Indonesia, the primary procurement context for UL AWM Style 3321 is appliance manufacturers and OEM equipment producers whose internal wiring specifications require a 150°C maximum XLPE construction — either because the 125°C ceiling of UL AWM 3271 is insufficient for a specific routing location inside the enclosed appliance assembly, or because the product is designed for export to North American markets where UL AWM Style documentation is required for the appliance-level UL evaluation.
Application categories where UL AWM Style 3321 is commonly evaluated for protected internal appliance wiring in this region include:
- Protected internal wiring inside enclosed commercial appliance assemblies — such as commercial electric grills, high-power toaster ovens, and commercial food service equipment — where internal routing locations near heat-generating components operate above 125°C during sustained full-power operation and a 150°C XLPE construction is specified as the cost-appropriate alternative to silicone rubber wire for those routing positions
- Large-conductor (2 AWG–4/0 AWG) internal power lead wiring inside enclosed equipment assemblies where the combination of 600 Vac / 750 Vdc rating and 150°C temperature class is required at the larger conductor cross-section, and where Indonesian industrial equipment procurement requires factory-direct supply at competitive per-metre pricing
- Appliance internal wiring at protected routing contact points where the optional treated or untreated braid covering of UL AWM Style 3321 is specified to provide additional surface protection at cable clips, routing passages, or conduit entries within the enclosed equipment structure
- OEM appliance assemblies where the equipment design specifies 150°C XLPE AWM wire for specific internal wiring locations and UL AWM Style documentation for that construction is required for the appliance-level evaluation
UL AWM Style 3321 is designated for the internal wiring of appliances. It is not designated for field wiring, building installation wiring, external cabling, or use outside protected internal equipment wiring. Current-carrying capacity and thermal derating must be confirmed at the equipment design level.
