IP66/65 electrical housing (PVC base with polycarbonate cover)

What does IP66 and IP65 mean?

IP66 and the IP65 standards applied to electrical housing designed to enclose electro-technical components.

Both standards are waterproof, the IP66 standard tests the device housing to a water velocity twice that of the IP65 standard, displaying the increased capabilities to withstand even the harshest wash-down environments used in any industry.

Another test frequently cited in the flow instrumentation industry, the IP67 standard, is an immersion test and does not test the device with the impact of powerful jets.

The IP66 standard is the highest and most relevant standard for control applications and for users who are washing the units down with spray jets.

Note that in the photograph below, a small oblong slot has been cut into the enclosure (top right side) that allows for a

reset rod to be mechanically connected to the high current circuit breaker (behind main contactor).

This will have a water seal fitted when assembled to maintain IP66/65 standards.

Another point to remember is that to maintain IP66/65 standards, there can be no open vents in the housing,

so keeping heat generating components outside the box may be required......

A - Heater SSR (solid Sate Relay) control

B - DC to DC converter SSR

C - KSI SSR control

All MOSFET output SSR's designed and thermally derated as per http://www.farnell.com/datasheets/77571.pdf

This panel hinges outwards to provide access to inside wiring....

High current cables lay to the rear of the box....
