Features:
- Places the TSE2 snubber network at equipment position A601.
- Belongs to the common rectifier of design-E SIMOVERT power units.
- Covers the documented 660–690 V three-phase, 50/60 Hz boundary.
6SE7031-4HE85-1JA0 is a dedicated rectifier assembly, so the TSE2 and A601 identifiers must be checked together.
The module is listed for feed units and for infeed/regenerative-feedback units, but only under specific complete host order numbers.
This order-number mapping prevents another board or another design size from being treated as the same snubber position.
The Siemens 6SE7031-4HE85-1JA0 TSE2 Snubber Circuit Capacitor Module may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

TSE2 assembly identity
- Network form: The TSE2 designation identifies a printed-circuit snubber RC network.
- Rectifier context: The network sits in the common rectifier instead of the electronics-control section.
- Shared assignment: The same TSE2 spare is listed for feed and regenerative-feedback variants.
- Identity check: TSE2, A601 and the complete 1JA0 order suffix must agree.
Position references in the rectifier
- Equipment code: A601 marks the installed snubber-network position.
- Adjacent entries: Separate V11–V26 references identify the power semiconductors, not this module.
- Reading method: A601 is a position reference and is not a stand-alone Siemens order number.
- Final match: The full 6SE7031-4HE85-1JA0 code confirms the spare assigned to that position.
Documented host-unit groups
- Feed pair: 6SE7033-5FE85-0AA0 and 6SE7034-2FE85-0AA0 use this TSE2 position.
- Regenerative group: 6SE7032-2HE85-0AA0, 6SE7033-5HE85-0AA0 and 6SE7034-2HE85-0AA0 carry the same spare.
- Role distinction: FE85 and HE85 identify different host-unit functions even when A601 is shared.
- Order boundary: Only the listed complete host codes establish the documented assignment.
Order-number verification sequence
- First: Confirm the installed power unit is design E.
- Second: Match its complete FE85 or HE85 host number to the documented list.
- Third: Locate the A601 position and read the TSE2 assembly marking.
- Last: Compare the full 6SE7031-4HE85-1JA0 spare-part suffix before selection.
