Product Description:
The HZF01.1-W045N is a filter module manufactured by Bosch Rexroth Indramat for the HZF Filter Modules series. It is part of Design 1 in Line 01 and is installed between the line supply and drive controllers to suppress conducted interference and stabilize current flow in industrial automation systems. By reducing line-side electrical noise, the module supports cleaner power delivery to connected drives in medium-power multi-axis installations. Its placement on the incoming power path lets it condition supply current before it reaches the drive electronics.
Electrical losses are a primary consideration for this module. Its nominal power handling capacity is 45 kW, while the allowable continuous current is limited to 80 A; together these ratings show the drive group that can be connected without thermal derating. Basic no-load dissipation is only 200 W, but once a drive consumes energy, loss rises by 4.5 W/kW of transmitted power. When the module operates at full load, aggregate heat generation reaches 400 W. Loss increases with transmitted power, so thermal behavior changes with system demand rather than remaining fixed at idle. This heat is removed by the surrounding air, so cabinet spacing and airflow must be arranged to keep internal temperatures within acceptable limits.
The housing uses natural convection as its cooling mode, so there are no built-in fans or liquid circuits to maintain. Power terminals accept conductors up to 25 mm², and the control terminals are limited to 1.5 mm², which helps match cable size to circuit duty. The unit has a height of 498 mm, along with a width of 175 mm and a depth of 262 mm, so it can be placed beside standard Rexroth inverters on a back plate. A total mass of 25 kg should be considered when selecting panel supports and mounting hardware. Clearance around the enclosure should also be left open so the passive airflow path is not restricted.
