Bussmann High Speed Fuse Fwa-12 Fwa-100a

The Bussmann High Speed Fuse Fwa-12 Fwa-100a supplied by Vicky Shu is a North American style bolted-tag fuse designed for rapid interruption of fault currents. It is rated for 150 V AC/DC under UL standards and also approved for 80 V DC operation. The current rating spans from 70 A to 1 000 A, covering a broad range of industrial applications. Interrupting performance includes 100 kA RMS symmetrical for 70-400 A and 200 kA RMS symmetrical for 450-1 000 A, with additional ratings of 20 kA at 150 VDC and 100 kA at 80 VDC.

The fuse element is typically a copper-alloy wire that melts quickly to clear faults, a construction common to high-speed fuses in the sector. Standard packaging for this class of fuse is a bolted tag with a protective ceramic or polymer housing, providing mechanical strength during installation. Typical industry practice specifies a voltage tolerance of +/-10 % and a current tolerance of +/-5 % for such devices. The UL recognition (JFHR2, E91958) and CE marking indicate compliance with safety and electromagnetic compatibility requirements widely accepted in global markets.

These fuses are commonly used to protect DC busbars, drives, power converters, rectifiers and reduced-rated voltage starters in manufacturing and renewable-energy facilities. Purchasers are usually system integrators, OEMs and large-scale plant operators who require documented performance data and traceability. Vicky Shu does not list minimum order quantities, lead times or Incoterms, so buyers should request those details directly from the supplier before finalising a contract.

Vicky Shu is listed with an address in the Power Supply Building, Room 411-412, Par Shenzhen, 518101, China. The supplier is classified as an imported tier and carries a harbor trust tier, indicating the platform’s verification of its trade credentials. No response rate is recorded, which suggests that communication speed may need to be confirmed directly. The profile does not disclose additional corporate details such as year of establishment or employee count.

The listing confirms that Vicky Shu offers the Bussmann High Speed Fuse Fwa-12 Fwa-100a but does not provide information on pricing, minimum order quantities, or production capacity. Certification status is limited to the UL and CE marks noted in the product description, and the supplier does not state any other quality management systems. Prospective buyers should therefore request formal certificates and any test reports relevant to their application.
