Mains Line Reactor (Choke)

Overview

A mains line reactor (choke) is required for the application. A mains line reactor is necessary to reduce the harmonics of the mains current. The mains line reactor must have at least 4% voltage drop at rated load.

Without UL /CSA Certification

Mains line reactor without UL /CSA certification:

oSchneider Electric: VW3SKLN016H003E for architectures up to 16 A single phase

With UL/CSA Certification

Mains line reactor with UL / CSA certification:

oSchneider Electric: VPM05D100000 for architectures up to 10 A

oSchneider Electric: VPM05D250000 for architectures up to 25 A

oSchneider Electric: VPM05D500000 for architectures up to 50 A

oSchneider Electric: VW3A4551 for architectures up to 4 A

oSchneider Electric: VW3A4552 for architectures up to 10 A

oSchneider Electric: VW3A4553 for architectures up to 16 A

oSchneider Electric: VW3A4554 for architectures up to 30 A

oSchneider Electric: VW3A4555 for architectures up to 60 A

A shielded version of the connection cables is not required.

NOTE: Verify that the rated current of the mains line reactor is above preset overload protection of the protective device.

Correlation Between Mains Current and DC Bus Current (3-Phase Operation)

The mains current is approximately the same as the DC bus current and corresponds to the current of the mains line reactor. For the design of the mains line reactor, use a dimensioning of the mains current of 100% to 110% of the DC bus current.

Mains Line Reactor and External Mains Filter

If a mains line reactor and an external mains line reactor are required, the mains line reactor and external mains filter must be arranged according to the following illustrations for EMC reasons.

The following graphic shows the wiring of drives with common mains fuse, mains line reactor, and mains filter (example shows three-phase drives):
