IP Ratings for Electrical Enclosures

IP ratings are defined by international standard IEC 60529. They use a dual numbering system to define levels of sealing effectiveness of electrical enclosures against intrusion from foreign bodies (tools, dirt etc) and moisture.

To find a B&R product by a specific IP rating, scroll down.

IP Rating Details

B&R Enclosures products are rated based on the following: First digit - intrusion of solid particles

• IP2X - Full penetration of 12.5 mm diameter sphere not allowed. 12.5 The jointed test finger shall have adequate clearance from hazardous parts.
• IP3X – Solid objects of 2.5mm diameter or larger shall not penetrate
• IP4X - Solid objects of 1.0mm diameter or larger shall not penetrate
• IP5X - Limited ingress of dust (no harmful deposits
• IP6X - Completely protected against the ingress of dust

Second digit - moisture protection

• IPX0 – no protection against water damage
• IPX2 - protected against vertically falling drops of water only
• IPX3 - protected against sprays to 60° from the vertical
• IPX4 - Protected against water splashed from all directions
• IPX5 - Protected against jets of water
• IPX6 - Protected against strong jets of water
• IPX7 - protected against the effects of temporary immersion between 15cm and 1m.
