Product Overview
The High Current ARC Resistance to Ignition Tester (Model: ZLT-DQY) is a professional instrument by ZLTJC to evaluate the fire resistance of materials used in enclosures within 13 mm (air distance) of arcing components (e.g., unenclosed commutators, switch contacts). It complies with UL746A Clause 32 and UL1082, generating controlled high-current arcs to test if materials ignite or propagate flames. This device is critical for ensuring fire safety in electrical equipment like motors, power tools, and switches—especially for markets requiring UL certification.
With an MOQ of 1 unit, the ZLT-DQY serves material manufacturers, electrical brands, and certification labs. It is shipped from Guangzhou Port (China) with a lead time of 30 days and supports T/T payment. Its design prioritizes consistent arc generation and data accuracy, making it a trusted tool for UL standard compliance.

Product Features
Precision Arc Control
Stable Arc Generation: The 33 A current circuit (0.5 power factor) ensures consistent arc intensity, replicating real-world arcing from components like commutators. This stability eliminates result variations from current fluctuations.
Precision Electrodes: Electrodes are manufactured to strict tolerances (3.5 mm copper, 3 mm stainless steel) with specific tip angles (30°, 60°), ensuring uniform arc formation.
Controlled Separation Speed: The 254 mm/s ±25 mm/s separation speed guarantees ≈40 arcs/minute, aligning with UL746A’s requirements for arc frequency.
Safety & Data Reliability
6-Digit Counter: Accurately records total arcs, allowing operators to track test duration and compare results against UL746A’s ignition thresholds.
Protective Enclosure: Shields operators from arc exposure, while overload protection prevents power supply damage.
Custom Voltage Options: Standard 380V 50Hz can be customized to 220V 60Hz (North America) or 230V 50Hz (Europe) for regional compatibility.
Application
Target Industries & Scenarios
Material Manufacturing: Testing plastic/rubber enclosures for electrical components (motor housings, switch covers) to ensure they resist ignition from nearby arcs.
Electrical Equipment Brands: Validating fire safety of finished products (power drills, fans, industrial motors) for North American markets (UL certification required).
Certification Labs: Conducting third-party UL746A tests to issue safety certifications for materials and components.
R&D Teams: Developing flame-retardant materials by measuring ignition resistance under controlled arcs, accelerating safer product innovation.
FAQ
What standards does the ZLT-DQY comply with?
It adheres to UL746A Clause 32 (high-current arc resistance) and UL1082 (electrical equipment safety), ensuring results are accepted by UL and global regulators.
How long does it take to receive the ZLT-DQY?
The lead time is 30 days from order confirmation, including manufacturing, calibration, and pre-shipment checks.
Can I adjust the number of arcs for testing?
Yes. The 6-digit counter allows setting target arc counts (e.g., 100, 500) or continuous testing until ignition. It stops automatically if the specimen ignites.
Is the power supply compatible with my region?
The standard is 380V 50Hz, but custom voltages (220V 60Hz, 230V 50Hz) are available. Specify your region when ordering.
What after-sales services are offered?
ZLTJC provides a 1-year warranty, 6-month calibration recommendations, and online technical support (email/video call) for setup and troubleshooting.
