Frequently Asked Questions

What is an IP rating?

An IP (Ingress Protection) rating is a two-digit code that defines how well an enclosure protects against solids like dust and liquids like water. It’s governed by international IEC standards.

What do the numbers in IP ratings mean?

The first digit indicates protection against solids (0–6), and the second digit indicates protection against liquids (0–9). For example, IP65 means “dust tight” and protected against water jets.

What’s the difference between IP55, IP65, and IP67?

IP55: Dust protected, protected from water jets

• IP65: Dust tight, protected from low-pressure water jets

• IP67: Dust tight, protected from immersion in water up to 1 meter for 30 minutes

Why is IP rating important when selecting motors?

Choosing the correct IP rating ensures your equipment is protected from environmental conditions like dust, rain, washdown spray, or immersion. This reduces failures and extends the life of your motor.

Does a higher IP rating mean better performance?

Not always. A higher rating means better protection, but it must be appropriate for the environment. Over-specifying can increase cost unnecessarily.
