The 5SJ4 series Siemens MCB family uses a numeric/alpha ordering code. The prefix 5SJ4 denotes the series; the digits following encode current rating and configuration. For this part, the C trip characteristic indicates a magnetic trip threshold roughly 5–10× the rated current, suitable for protected circuits with moderate inrush such as lighting banks and branch loads with low starting currents.

Key Specifications
- Actuator Type: Lever (manual reset required after trip)
- Mounting Type: DIN Rail
- Encapsulation: Bulk
- Illumination: None
The dual-pole configuration provides simultaneous disconnection of line and neutral, which is typical for branch protection in industrial panels and certain equipment-feed applications.
Installation Context
This MCB mounts on standard 35 mm DIN rail in compatible enclosures. The lever actuator permits manual switching and visual status indication. No auxiliary contacts or busbar accessories are listed in the catalog record; those options are typically available within the broader 5SJ4 family but must be verified against specific product variant tables.
Catalog Comparison
The table below shows the seed part alongside three highest-similarity in-catalog rows. Similarity is a parametric proximity metric only — these rows require the reader's own qualification before substitution.
| MPN | Poles | Current | Trip | Voltage (title) | Breaking Capacity | Similarity |
|---|---|---|---|---|---|---|
| 5SJ42167HG41 | 2 | 16A | C | 240V | 14K | — |
| 5SJ4216-7HG42 | 2 | 16A | C | 480/277V | 10K | 1.00 |
| 5SJ42168HG41 | 2 | 16A | D | 240V | 14K | 0.88 |
| 5SJ4216-8HG42 | 2 | 16A | D | 480/277V | 10K | 0.88 |
Why 5SJ4216-7HG42 is parametrically similar
Shares the same current rating (16A), trip characteristic (C), number of poles (2), and mounting type. The voltage rating in its title reflects a higher system voltage (480/277 V) and a different breaking capacity (10 kA vs 14 kA), which may affect coordination in specific panel designs.
Why 5SJ42168HG41 is parametrically similar
Shares the same current rating (16A), voltage class (240V), breaking capacity (14 kA), and physical form factor. The primary difference is the trip characteristic — D-trip has a higher magnetic threshold (roughly 10–20× rated current), which changes the coordination profile for circuits with higher inrush.
FAQ
What does the C trip characteristic mean for 5SJ42167HG41? The C curve indicates a magnetic trip band approximately 5–10× the 16 A rated current. This is appropriate for circuits with moderate inrush such as lighting loads and general-purpose branch protection.
How does 5SJ42167HG41 differ from the D-trip variant 5SJ42168HG41? Both are 2-pole, 16 A, 240 V MCBs with 14 kA breaking capacity. The D-trip version has a higher magnetic threshold, making it suitable for circuits with higher starting currents such as motors or transformers.
What mounting method does this MCB use? Both the seed part and its catalog peers mount on 35 mm DIN rail per the standard specified in the records.
