Product details

The Siemens SENTRON 5SY5201-6CC is a 2-pole DC miniature circuit breaker with B tripping characteristic, rated 0.93 A at 40 °C and 440 V DC. For a DC control circuit or a PV string combiner, the B curve (3-5 In) handles moderate inrush without nuisance trips. The 2-pole version switches both lines; polarity must be observed on supply connection.

Halogen-free and silicon-free construction. Ambient operating range -40 °C to 75 °C; humidity limits: 95% up to 55 °C, 55% up to 70 °C, 35% at 75 °C. Vibration resistance per IEC 60068-2-6: ±1 mm at 5–25 Hz, 50 m/s² at 25–150 Hz. Sealable for tamper-proof installations. Not designed for neutral conductor switching.

Frequently asked questions

Where can I buy 5SY5201-6CC?

It is sourced through independent distribution and quoted to order against an RFQ. Submit a request for current availability and pricing.

What is the breaking capacity of 5SY5201-6CC?

10 kA at DC per IEC 60947-2, with a maximum operating voltage of 500 V DC.

What is the temperature range for 5SY5201-6CC?

Operating ambient -40 °C to 75 °C, with humidity derating above 55 °C.

Will 5SY5201-6CC drop into a panel specified around 5SY5240-7?

Both are 2-pole SENTRON DC MCBs on the same DIN-rail footprint (2 MW), so mechanical fit is identical. The key difference is the current rating: 5SY5201-6CC is 0.93 A, while 5SY5240-7 is a higher-rated variant. Check your load current before substitution.
