AFE in IP21 Rittal Enclosure
Main Component Sections
shows a basic one-line diagram for an AFE system in an IP21 Rittal
enclosure. The main component sections consist of the following items:
• AC line switchgear consisting of the input disconnect (Q0) and MCCB
motor-controlled circuit breaker (Q1)
• LCL filter (L1)
• Precharge circuit
• AFE power structure (U1) with AFE control assembly
• DC fuses (F2.1 and F2.2)
