160 A Polybloc distribution block
The 160 A Polybloc is made up of individual elements that can be used alone or with
others to make two-pole, three-pole or four-pole distribution blocks.
Mounting is very fast. It clips onto a modular rail and is supplied by cables via a tunnel
terminal.
The connection spring terminals are slanted to facilitate cable entry and bending of
the flexible and rigid cables.
It is supplied with a cover that also guides the cables.

Three 160 A Polybloc distribution blocks in the vertical position
on a modular rail, supplied by an NG125.
Electrical characteristics
rated insulation level Ui = 750 V
short-circuit withstand current: the reinforced breaking capacity due to cascading
in circuit-breaker combinations is maintained. The worst-case situations were tested.
The electrical characteristics are perfectly compatible with the connected devices.
Neither the temperature derating curves nor the performance levels of the circuit
breakers and switch-disconnectors are altered.
impulse withstand voltage Uimp = 8 kV.
Supply
Direct to a tunnel terminal, for cables up to 70 mm².
Distribution
Via cables, up to six 16 mm² cables.
Installation
The blocks clip onto a modular rail.
