UL 1017 Figure 4 IEC Articulate Accessibility Probe with Stop Plate

This dual-compliant safety probe is engineered to meet the specifications of both International Electrotechnical Commission (IEC) standards and UL 1017 Figure 4 requirements. It serves as a critical tool for assessing the accessibility of hazardous live parts, such as high-voltage windings and terminal blocks, through equipment openings including vents, panel seams, and terminal apertures in transformers, power supplies, and industrial reactors. The probe features a rigid conductive stainless steel tip precisely dimensioned per UL 1017 Figure 4 and a heat-resistant insulated handle.

Specifications:
Tool Type: IEC/UL 1017 Figure 4 Dual-Compliant Safety Probe (for hazardous part accessibility testing in transformers and power supplies)
Key Dimensions:
– Knurled Finger Diameter: 12 mm
– Knurled Finger Length: 80 mm
– Baffle Plate Diameter: 50 mm
– Baffle Plate Length: 100 mm
– Baffle thickness: 20 mm
Core Function: Detects accessible hazardous live parts in transformers and power supplies; ensures compliance with IEC standards and UL 1017 Figure 4

Test Procedures:
1. Inspect the probe for any damage, including bent tip, cracked insulation, or compromised conductivity, and verify structural rigidity.
2. Power on the equipment under test (EUT), such as a commercial transformer, and configure it to normal operating conditions.
3. Grasp the insulated handle and align the 8mm probe tip with EUT gaps, such as vents or terminal panel seams.
4. Apply a consistent 30N thrust force to the probe, advancing until resistance prevents further insertion.
5. Monitor the connected live-part detector for any signals indicating contact with hazardous parts.
6. Document results: Pass if no contact is detected; Fail if live parts are accessible.

Applications:
1. Testing vent gaps in industrial transformers in accordance with UL 1017:2023 Figure 4 to prevent access to high-voltage windings.
2. Quality assurance during manufacturing of medical device transformers, including ultrasound machine power units.
3. Post-production verification of panel seams in industrial reactors to comply with North American and international safety regulations.
