New product announcement
Distribution blocks
We are pleased to announce that Distribution Blocks
are now released for sale.
Distribution blocks are used to realize single-, two-, threeand four-phase systems up to a rated current of 400 A. This
enables to split power supply circuits in several load circuits
with different cable cross-sections.
The following Distribution Blocks are SCCR rated only with
Class J Fuses. See detailed technical sheet on the next page.
High thermic and mechanical robustness
Distribution blocks are made of thermoplastic with electrical and mechanical parts, which allows a usage under high thermic and mechanical load according to
IEC 60947-7-1.
Highlights
n
Fast mounting on DIN-Rail with click connection
or on mounting plate with 2 x M5 screws
n
Place saving
n
Safety because of IP20 degree of protection
and no cap to open or remove
