Product Description:
The HNL05.1R-0040-N1019-N-A4-NNNN Mains Choke of Bosch Rexroth Indramat is designed to meet the requirements of an industrial power system which requires high current carrying capacity and inductance regulation. The 40 µH nominal inductance of this choke assists in minimizing harmonic distortion in power supply lines.
A nominal current of 1019 A means that this choke is suitable to handle big industrial drive loads that demand high power. The working voltage of this choke lies in the range of 3 x AC 380 V -15% and 500 V +10% which allows a wide input supply within industrial conditions. The core of this choke is made of laminated steel to minimize the losses due to eddy current during high-frequency operations. This core also increases the control over the magnetic field for better performance at higher currents. For thermal control, the HNL05.1R-0040-N1019-N-A4-NNNN Mains Choke employs passive natural air cooling with air gaps, without the requirement of forced air or liquid cooling systems. This passive cooling is backed by a power dissipation rating of 850 W (air) to ensure thermal stability under continuous operation. This choke operates successfully under a maximum ambient temperature of 40 °C, ideal for typical industrial environments with ventilated conditions.
This choke’s mechanical build makes it easy to mount, and it has four mounting holes, Ø12 mm in diameter, designed as 20 mm long slots to provide alignment flexibility when mounted. The protection rating of this choke is IP00, which indicates an open structure that is not environmentally sealed, and it should be mounted inside a protected electrical enclosure to avoid exposure to dust or moisture. In terms of physical size, the HNL05.1R-0040-N1019-N-A4-NNNN has a height of 543.5 mm, a width of 498 mm, and a depth of 204 mm. This choke also has a weight of 121 kg to ensure mechanical stability after mounting.
Frequently Asked Questions about HNL05.1R-0040-N1019-N-A4-NNNN:
Q: Why is laminated steel used in the core of HNL05.1R-0040-N1019-N-A4-NNNN?
A: Laminated steel reduces eddy current losses during high-frequency operations. This helps improve magnetic efficiency and lowers unwanted heat buildup.
Q: How does natural air cooling with air gaps benefit this Mains Choke?
A: Natural air cooling with air gaps ensures passive heat dissipation without extra fans. It minimizes maintenance needs and improves system reliability.
Q: What is the impact of 850 W power dissipation on installation planning?
A: The 850 W dissipation requires proper ventilation within the control cabinet. Adequate airflow will prevent temperature rise and maintain performance.
Q: Why is the IP00 rating important for HNL05.1R-0040-N1019-N-A4-NNNN?
A: An IP00 rating means the unit lacks environmental sealing. This requires indoor installation inside an enclosed control panel.
Q: How does the Ø12 mm mounting slot design help during assembly?
A: The Ø12 mm, 20 mm long slots provide flexible mounting adjustments. This ensures precise alignment during mechanical installation.
