Product details

Siemens 5SY6140-7 SENTRON MCB — C-curve, 1-pole, dual-rated breaking capacity

At DC under IEC 60947-2 it handles 15 kA at 60 V (max 72 V), and under UL 1077 / CSA C22.2 No.235 it carries a 5 kA rating — covering the North American supplementary protector role.

For DC circuits, the 15 kA rating at 60 V covers battery-backed control buses or solar combiner boxes within the voltage limit. Rated operational voltage is 400 VAC single-phase (440 V max), 60 VDC (72 V max). Ambient temperature range is -40 °C to 75 °C, with humidity derating: max 95% RH at 55 °C, dropping to 35% RH at 75 °C.

Certified to IEC/EN 60898-1, IEC/EN 60947-2, and UL 1077 / CSA C22.2 No.235. The dual-standard marking means one part number covers both European distribution-board specs and North American supplementary protector requirements — simplifies global panel builds. RoHS, REACH, and CE documentation is standard for the SENTRON line; the manufacturer provides a declaration of conformity and material compliance data on request.

Frequently asked questions

Where can I buy 5SY6140-7 and how do I get a price?

The 5SY6140-7 is sourced to order through independent distribution. Submit an RFQ for current availability and pricing — confirmed at quote time.

What is 5SY6140-7's listed depth (76 mm) on this component line?

The 5SY6140-7 has a depth of 76 mm, a width of 18 mm (1 modular unit), and a height of 90 mm. Installation depth is 70 mm.

What compliance documentation does this brand provide for 5SY6140-7 (RoHS, REACH, UL, IEC)?

The 5SY6140-7 carries dual certification to IEC/EN 60898-1 and IEC/EN 60947-2, plus UL 1077 / CSA C22.2 No.235. Standard RoHS, REACH, and CE documentation is available from the manufacturer.

Will 5SY6140-7 drop into a panel that was specified around 5SY6332-7CC without rewiring?

Both are 1-pole SENTRON MCBs on the same 18 mm modular footprint with identical DIN-rail mounting, so the 5SY6140-7 fits the same panel cutout and busbar arrangement. The key difference is the trip curve: 5SY6140-7 is C-curve, while 5SY6332-7CC is a different characteristic — verify coordination with downstream loads before swapping.
