What cables are usually compared with 60245 IEC 57? 

---

Q1: What is the difference between 60245 IEC 53 and 60245 IEC 57 cables?

A1: 60245 IEC 53 ordinary duty flexible rubber sheathed cord is rated 300/500V with standard rubber sheath, without oil resistance. This cable is suitable for dry, damp indoor environments for light-duty power supply.

While 60245 IEC 57 ordinary duty flexible rubber sheathed cord is rated 300/500V, fitted with SE4 oil-resistant rubber sheath. This cable offers excellent oil resistance, ideal for equipment with oil components.

Q2: What is the difference between 60245 IEC 57 and 60245 IEC 66 cables?

A2: 60245 IEC 57 is 300/500V ordinary duty rubber sheathed cord with SE4 oil-resistant sheath, for portable tools, household appliances and temporary light wiring.

While 60245 IEC 66 heavy duty rubber sheathed cord is rated 450/750V. This cable has thicker rubber sheath, stronger mechanical abrasion resistance, designed for heavy-load mobile applications. It comes at a higher cost.

Q3: What is the difference between 60245 IEC 57 and H05VV-F cables?

A3: 60245 IEC 57 is oil-resistant rubber flexible cord. This cable keeps good flexibility under low temperature, works well in damp or wet locations.

While H05VV-F is PVC insulated and PVC sheathed flexible cord. This cable is low cost, but poor in oil resistance and low-temperature flexibility, not recommended for oily or cold conditions.

Q4: What is the difference between 60245 IEC 57 and H05RN-F cables?

A4: 60245 IEC 57 follows IEC 60245-4 standard.

H05RN-F is European harmonized rubber flexible cord. Both 245 IEC 57 and H05RN-F share identical construction, voltage rating 300/500V, oil-resistant SE4 sheath and colour coding rules, they can be mutually replaced for most projects.
