PL5 Series Enclosures Technical Information

To ensure that the maximum temperature as permitted by certification is not exceeded, the dissipated wattage factor formula is used: W = N x F x I² (see enclosure wattage factor).

It is not permitted to fit more than one conductor per side in rail or direct mounted terminals unless using an insulated Bootlace Ferrule.

Linked and mixed terminal arrangements other than those specified in the data tables are available, but the voltage and current figures may be affected to ensure the maximum certified wattage factor is not exceeded. Please contact Hawke Technical Sales for more information.

When connecting a terminal with a conductor that is less than maximum size permitted for that terminal type, the maximum amps per pole must be reduced to suit i.e. an WDU10 (10mm²) terminal fitted with a 4mm² conductor will have the current rating reduced to that of the current rating permitted through the WDU4 (4mm²) terminal.

For Intrinsically Safe Applications, Exe power terminals can be supplied in blue on request. (Note: the enclosure will remain Exe certified).

An earth terminal must be fitted inside the enclosure. (Note: Power terminals may be used as ‘clean earths’).

PL5 Enclosures have metric clearance entries as standard.

Entries into the enclosure must be via a suitable, approved entry device.

All unused entry holes must be fitted with a stopping plug as listed on the enclosure certificate.

Earth Continuity

These Enclosures may be fitted with an earth continuity plate in plated mild steel as standard or optional brass when requested by the customer. (Note: A locknut is required on Cable Glands and metal stopping plugs to ensure earth continuity through the plate).

Enclosures Dissipated Wattage

Dissipated Wattage Factor

The Dissipated Wattage Factor of the enclosures has been established by test to ensure that the maximum temperature as permitted by temperature certification is not exceeded. When terminal quantities greater than those at maximum amps are required (up to maximum physical quantity only) then the current shall be reduced accordingly to remain within the Dissipated Wattage Factor of the enclosure.

Combined Terminal Resistance Factor

This factor is used to determine the number of terminals that can be accommodated within the enclosure without exceeding the Wattage Factor. The Combined Terminal Resistance Factor is the sum of the individual terminal resistance's and the resistance of the cable core equal in length to the enclosure maximum diagonal. (Core Resistance is taken from BS6360). Combined terminal resistance factor.

Wattage to be Dissipated = N x F x I²

N = Number of Terminals. F = Combined Terminal Resistance Factor. I = Maximum Current.

e.g. Number of terminals in a PL630 Enclosure at 20.8 Watts - 10 x 'WDU 2.5' (1=17A), 2 x 'WDU 6' (1=29A), (10 x 0.003035 x 17 ² = 8.77 watts) + (2 x 0.001404 x 29 ²) = 2.36 watts). Total Watts = 8.77 + 2.36 = 11.13 watts.

Therefore this terminal combination is acceptable as the wattage is less than that of the PL630 maximum watts of 20.8 watts.

Note - If a smaller than maximum permitted conductor is fitted into a power terminal, then the smaller conductor resistance must be used when calculating the combined terminal resistance.
