Product details

The Siemens 6EP3436-8SB00-0AY0 is a SITOP modular power supply rated for 20 A output with a three-phase input range of 400 to 500 VAC at 47 to 63 Hz.

Ratings and approvals

The unit carries cULus listing under UL 508 and CSA C22.2 No. 107.1 (File E197259), plus cCSAus to UL/CSA 60950-1. CE, EAC, and C-Tick marks are present; ATEX and IECEx are not covered. IP20 protection means it is intended for dry indoor panels only.

Mounts via snap-on to DIN rail EN 60715 35x7.5/15. Input terminals (, L2, L3, PE) accept 0.2 to 4 mm² single-core or finely stranded wire; output terminals (+, -) are dual screw terminals for the same wire range. A 3-pole miniature circuit breaker (6 to 16 A, characteristic C) or a Siemens 3RV2011-1DA10 (3 A setting) is required in the feeder.

Frequently asked questions

What approvals does this power supply carry?

It carries cULus listing (UL 508, CSA C22.2 No. 107.1), cCSAus (UL/CSA 60950-1), CE, EAC, and C-Tick marks. ATEX and IECEx are not covered.

What is the rated output current and input voltage range?

Rated output current is 20 A. Input voltage range is 400 to 500 VAC three-phase at 47 to 63 Hz.

Does it provide galvanic isolation?

Yes, the output is safety extra-low voltage (SELV) per EN 60950-1 with galvanic isolation from the input.
