RUKO KEB-HM-44.0mm 3-Phase Mains Choke Toroidal Core 0.2mH 1.5A 400V AC

The KEB-HM-44.0mm from RUKO GMBH is a 3-phase mains choke with a toroidal core design, engineered to reduce harmonics and limit peak currents in frequency inverter and motor drive applications. Its 44 mm core diameter and 0.2 mH nominal inductance provide effective filtering in a compact form factor.

Highlights

• 3-phase toroidal mains choke with 0.2 mH inductance
• Rated current 1.5 A at 400 V AC (max 690 V AC)
• Insulation class F (155 °C) for reliable thermal performance
• Flexible leads for easy connection; screw mounting
• Operating frequency 50/60 Hz; ambient temperature -25 to +40 °C

In daily use

This choke is intended for integration into electrical enclosures or machinery where harmonic distortion and current spikes need to be controlled. The toroidal core ensures low magnetic leakage and efficient inductance. With IP00 protection, it must be installed in a protected environment. The flexible leads allow straightforward wiring to terminals or busbars.
