Auxiliary current switch for 5SX2+4+5 series breakers. Provides one Normally open and one Normally closed contact that follows the breaker's on/off state. Rated for 230 V supply and 6 A switching current, the 5SX9100HS handles the signal-level loads typical in a control cabinet: indicator lamps, PLC digital inputs, or contactor coils within that current envelope. The mountable form factor clips directly onto the breaker's side, saving DIN-rail space compared to a separate interposing relay.

Frequently asked questions
What replaces 5SX9100HS?
No official successor order code is published. The functionally identical peer 5SX9100-HS carries the same contact configuration (1NO+1NC), same 230 V / 6 A ratings, and same mounting interface for 5SX2+4+5 breakers. It is the closest drop-in candidate, but verify the marking difference against your panel documentation.
What breakers does the 5SX9100HS fit?
It is designed for use with Siemens 5SX2, 5SX4, and 5SX5 series miniature circuit breakers. It mounts directly to the side of the breaker, sharing the same DIN-rail footprint.
What is the contact configuration?
One Normally open and one Normally closed contact. Both are rated for 6 A AC / 1 A DC switching at 230 V.
Will 5SX9100HS drop into a panel specified for 5SX9100-HS?
Yes — the two order codes share identical ratings, contact arrangement, and mounting interface. The only difference is the order-code marking on the part itself. No rewiring or panel modification is needed.
