JSHAS80 Disconnector: Application and Ordering Checks
Identify the JSHAS80 configuration and confirm isolation duty, mounting, handle arrangement and electrical data before ordering.
In this article
The JSHAS80 introduction shows a disconnector family. For a replacement or new panel, begin with the complete marking and installation drawing; a family designation alone does not define every available configuration.
Identify the required function.
Establish whether the circuit requires isolation only or documented load switching as well. The ability to carry current is different from the ability to interrupt it. Confirm the specific device’s function and rated duty in the manufacturer’s data.
Compare the mechanical arrangement.
Review the mounting position, operating handle, enclosure interface and space for conductors. Where a lockable isolation arrangement is required, confirm the suitable handle and accessories for the chosen assembly. Similar-looking parts are not automatically interchangeable.
Information for a replacement enquiry.
- A clear photograph of the existing label and complete part number.
- The circuit voltage, AC/DC type and operating current.
- The number of poles and existing connection drawing.
- Installation dimensions and the required operating arrangement.
The original product illustrations accompany this overview. For a new application, send the requirements to Jinhong and request the relevant technical documents. Use the disconnector and circuit-breaker comparison to understand the difference between isolation and overcurrent protection.
Background: the functions of disconnectors and load-breaking switches.
JSHAS80 replacement information pack
Use the exact marking on the existing unit as the starting point. Similar JHAS catalogue names must not be treated as proof of equivalence to the JSHAS80 designation in this article.
| Check | Information to record |
|---|---|
| Existing unit | Photograph the complete marking and retain the existing connection drawing. |
| Mechanical interface | Record handle, mounting, enclosure interface and available conductor space. |
| Electrical duty | State voltage, AC/DC type, current, poles and whether load breaking is required. |
Can I choose a replacement from its handle and outer dimensions?
Those details help identify the installation, but they do not establish electrical equivalence. Confirm the full device designation, duty and connection diagram before choosing a replacement.
