Siemens 5SJ4130-7HG40 Miniature Circuit Breaker
Catalog Identity and Device Summary
The 5SJ4130-7HG40 is a single-pole, 30 A miniature circuit breaker (MCB) from Siemens' 5SJ4 series, intended for DIN rail mounting in branch protection applications. It carries multi-agency approvals including CCC, CE, CSA, EAC, UL, and VDE, supporting use in equipment destined for several regulatory jurisdictions.

Approvals and Compliance
The unit is listed under CCC, CE, CSA, EAC, UL, and VDE. These approvals cover basic branch-protection coordination use cases; the reader's engineering team must confirm whether this combination satisfies the specific standards required for a given installation or equipment type.
Selection Trade-offs
- Breaking capacity (14K): The 14 kA interrupting rating provides higher fault-withstand capability than 10 kA alternatives; selecting a lower rating may reduce cost but narrows coordination flexibility in higher prospective fault current systems.
- Voltage class (240 V vs. 277 V): The seed part is rated 240 V; some alternates (e.g., 5SJ4130-7HG42) carry 277 V ratings, which may suit single-phase 277 V supply systems common in North American commercial installations.
- Trip characteristic: The title references "SAME PH 14K"; alternates distinguish C-trip and D-trip curves, which govern the instantaneous pickup range and thus the breaker's suitability for purely resistive versus inductive load profiles.
- Package format: The seed ships in bulk packaging; several alternates use box packaging, which may matter for automated assembly or controlled-quantity stocking.
- RoHS non-compliant: All listed parts carry this designation, which may affect equipment destined for markets with substance-restriction requirements.
Similar Catalog Parts
The table below presents in-catalog peers sharing the same category and matching on rated current, voltage, pole count, and mounting. All require the reader's own engineering qualification before use as a substitute.
| MPN | Current | Voltage | Poles | Mount | Breaking Capacity | Package |
|---|---|---|---|---|---|---|
| 5SJ4130-7HG40 | 30 A | 240 V | 1 | DIN Rail | 14K | Bulk |
| 5SJ41307HG41 | 30 A | 240 V | 1 | DIN Rail | 14K | Bulk |
| 5SJ4130-7HG42 | 30 A | 277 V | 1 | DIN Rail | 14K | Bulk |
| 5SJ4130-8HG40 | 30 A | 240 V | 1 | DIN Rail | 10K | Box |
Why these parts are similar: All are Siemens 5SJ4-series single-pole DIN-rail MCBs with 30 A rating and identical actuator, illumination, and mounting specifications. The shared typed specs (rated_current_a, voltage_v, poles, mount) yield high parametric overlap.
- 5SJ41307HG41 differs only in MPN formatting (no hyphen after "5SJ41"); it matches the seed on voltage, poles, breaking capacity, and package.
- 5SJ4130-7HG42 carries 277 V instead of 240 V, which may suit higher system nominals but requires coordination review at the higher voltage.
- 5SJ4130-8HG40 drops the breaking capacity to 10 K and switches to box packaging, making it a lower fault-current option.
