CATU MX-430-M Earth resistance tester Selection Notes
The CATU MX-430-M Earth resistance tester is part of Safetyware’s electrical protection range for electricians, utilities, industrial maintenance teams, substations and facilities that need controlled protection against shock, arc flash, short-circuit or emergency rescue hazards. Review it against the actual task, voltage exposure, isolation status and site procedure before issue.
Where It Fits
| Selection area | Practical guidance |
|---|---|
| Product family | Earthing or discharge equipment |
| Typical application | Electrical maintenance, switching, testing, isolation, substation work, panel service or emergency readiness. |
| Procurement note | Confirm fault rating, connection point, lead length and correct work sequence. |
Standards and Safe Work Notes
Electrical protection should support a planned safe-work sequence: isolate where practical, lock out and tag out, verify absence of voltage, control stored energy, then use rated PPE and tools for the remaining risk. Local buyers should confirm datasheets, applicable EN/IEC/ASTM markings and DOSH/SIRIM KPD documentation where required.
Common Questions
Can this be used for live electrical work?
Only if the product rating, condition, procedure and user competency match the task. Electrical work should be de-energised and isolated whenever practical.
Can I request datasheets or matching accessories?
Yes. Contact Safetyware to compare ratings, sizes, compatible accessories or documentation for your site.
