Product details

2.5 A output with derating above 55 °C

The 6EP3332-6SB00-0AY0: Inrush is bounded by an I²t maximum of 3 A²·s, which lets the panel builder coordinate a 10 A characteristic B or 6 A characteristic C miniature breaker on the AC feeder without nuisance trips during parallel-bank cold-start.

Wide-range AC input with DC backup feed

Input accepts 85 V AC at the initial cut-in up to 264 V AC full-scale across 47–63 Hz line frequency, and the same terminal set takes 110–300 V DC for battery-backed or DC-bus plants, which removes the need to stock a separate DC-only SKU for the same load.

Approvals carry the panel through every jurisdiction on the BOM

Output is safety extra-low voltage (SELV) per EN 60950-1 and EN 50178 with internal fuse protection and IP20 touch-safe terminals, which keeps the 24 V rail under the touch-current limit and removes the need for additional shrouding on the field side.

DIN rail footprint and panel-side clearances

The housing snaps onto EN 60715 35×7.5/15 DIN rail and is rated for direct mounting in non-standard orientations, but the manufacturer calls out 20 mm clearance at the top and bottom of the unit with 0 mm on the left and right, so the cabinet layout must leave vertical breathing room for the natural-convection cooling path even when the unit is loaded against the side of an adjacent device.

Production status and where this part is sourced from

Lifecycle stage is recorded as current production, and the unit is supplied through independent distribution with availability and current pricing confirmed against an RFQ—quoting the exact order code, the project quantity, and the target ship date is the fastest path to a firm lead time for a BOM position.

Frequently asked questions

How do I order 6EP3332-6SB00-0AY0 and confirm current availability?

The listed lifecycle stage is current production, so the part is sourced as a current-production SKU rather than through last-time-buy or surplus channels.

What compliance documentation ships with 6EP3332-6SB00-0AY0?

ATEX, IECEx, FM, and UL hazardous-location approvals are not on the record for this SKU.
