Product Description:

The HZF01.1-W010N filter module is produced by Bosch Rexroth Indramat as part of the HZF Filter Modules series. It is a passive line component installed between the mains supply and drive controllers to limit conducted interference and help stabilize incoming power for automated machinery. Because it works in the incoming supply path, it conditions the electrical line rather than generating controlled motor output on its own. This placement helps reduce unwanted electrical noise before it reaches connected drive electronics inside the cabinet.

The module carries a continuous nominal current of 18 A, so connected drive groups must remain within that load level on a single filter branch. The filter produces basic losses of 100 W, which appear as heat at rated load even when the connected drives are not actively delivering mechanical output. During operation, additional load-dependent losses rise by 10 W/kW, which makes enclosure heat buildup easier to estimate as machine demand changes. At full design capacity, the total power loss reaches 200 W, and that value directly affects cabinet ventilation requirements. The module is intended for three-phase mains, matching the supply arrangement used by most Indramat drive systems. An IP10 protection category means that only solid objects larger than 50 mm can enter, so the filter must be mounted inside an enclosed panel to prevent accidental contact with energized parts.

The mechanical envelope measures 150 × 262 × 498 mm, which allows the module to sit beside rectifier, brake, and capacitor units in standard industrial cabinets without consuming unusual depth. With a mass of 18 kg, the housing is substantial enough to require secure support on shelves or mounting hardware during installation. Its rectangular form also leaves room for adjacent power components and cable routing in a typical enclosure layout. The housing and internal cores release heat mainly through natural convection, so clear airflow paths around the unit help warm air move upward through the cabinet. If surrounding ambient temperature rises or several power devices share the same enclosure, added airflow can help control internal heat buildup.
