Product details

The 5SP3225-3: The E characteristic (tripping class E) provides a defined overload and short-circuit response curve. Degree of pollution 3 confirms the part is rated for conductive pollution environments typical in industrial and infrastructure panels.

Occupies 3 modular width units. Depth is 76.3 mm, height 128 mm. Saddle terminals and infeed at box terminal are standard. IP40 protection with connected conductors. Integrated locking slide allows sealing with a lock, wire seal, or cable ties — useful for tamper-proof installations.

Shock resistance: 30 g for at least 3 impacts, 11 ms duration. Vibration resistance: 2 g, 20 frequency cycles 5 to 150 to 15 Hz per IEC 60068-2-6. Mechanical service life typical 20,000 operating cycles.

Frequently asked questions

What is the difference between 5SP3225-3 and 5SP4292-7?

The 5SP4292-7 is a different SENTRON variant. The 5SP3225-3 is a 2-pole E-curve MCB rated 25 kA at 400 V; the 5SP4292-7 has different pole count and rating. They are not direct drop-in replacements without verifying the panel's coordination study.
