PRODUCT DESCRIPTION
6EP4438-7FB00-3DX0 SITOP SEL1200 Eight-Channel Selectivity Module
Siemens 6EP4438-7FB00-3DX0 is a SITOP SEL1200 selectivity module that divides a regulated 24 V DC supply into eight protected output channels. Each channel has an adjustable 2 to 10 A response threshold, with a 60 A rated total input. The output voltage follows the input minus approximately 0.2 V.
Sequential connection can be set to 25 ms, 200 ms, 500 ms or a load-optimized mode. Each channel has three-color status indication, with remote reset and a common status interface. The switching characteristic disconnects overloads according to the current multiple; switching off a channel does not provide galvanic input-output isolation.

SYSTEM INTEGRATION
Integrate 6EP4438-7FB00-3DX0 within SITOP SEL1200
Supply the selectivity module from a regulated 24 V DC source within its 20.4 to 30 V input range. Coordinate the eight branch settings with their actual loads and conductors, keeping the combined demand within the 60 A input rating.
Set each channel threshold between 2 and 10 A, then choose the sequential-start delay appropriate to the loads. The selectable 25 ms, 200 ms, 500 ms and load-optimized modes control branch connection after the supply has risen above the documented start level.
Integrate the status interface and remote reset using their documented electrical arrangement. A reset high signal requires more than 15 V. The module has no galvanic isolation between input and output in the switched-off state, so channel switching must not be treated as a safety isolation method.
Features:
- Nominal input: 24 V DC
- Input voltage range: 20.4 to 30 V DC
- SITOP SEL1200
Use 6EP4438-7FB00-3DX0 only within the documented SITOP SEL1200 arrangement and applicable installation instructions.
INTERCHANGEABILITY
Replace 6EP4438-7FB00-3DX0 within SITOP SEL1200
Record all eight channel thresholds, start-delay settings and monitoring connections before replacing 6EP4438-7FB00-3DX0. Match the SEL1200 switching characteristic instead of assuming another SITOP selectivity module behaves identically.
Isolate the upstream DC source and any possible backfeeding branches before removal. Label the eight load connections and status wiring, and inspect the branch conductors for the cause of any persistent trip rather than increasing thresholds to conceal it.
Restore the branch settings and check staged connection, status indication and remote reset. Confirm each load remains within its intended current limit, then verify the monitoring interface reports the channel state expected by the controller.
Features:
- 6EP4438-7FB00-3DX0 complete order code
- Off-state input-output isolation: No galvanic isolation
- Retain the documented SITOP SEL1200 connection arrangement
Use 6EP4438-7FB00-3DX0 only within the documented SITOP SEL1200 arrangement and applicable installation instructions.
