The 3LD series covers motor disconnect and maintanance switching in industrial enclosures. The suffix "TL" denotes a 3-pole plus neutral configuration, distinguishing it from "TK" variants that omit the neutral pole. Frame size derives from the base number 3LD3330, implying a 40 A rated current at up to 690 V AC.

Readers must qualify each variant independently; similarity values reflect catalog proximity, not suitability for specific applications.
- 3LD3330-1TK13 shares voltage, current, and series with the seed. The TK suffix indicates 3-pole without neutral; selected when the application does not require N-pole isolation in the disconnect path.
- 3LD3330-0TL13 matches on pole count, voltage, and current. The leading "0" in the suffix block indicates a different actuator or handle option compared to the seed's "1" prefix. Confirm actuator style matches the enclosure cutout and operation requirement.
- 3LD3330-0TK13 is a 3-pole variant with the "0" actuator option. Suitable where neutral switching is unnecessary and the "0" handle style aligns with existing Siemens 3LD panel integrations.
- 3LD3330-1TL11 is a lower-suffix variant within the same 3P+N 40 A family. The "11" tail typically denotes a different color actuator or specific accessory package; verify against Siemens ordering guide if the "11" variant matches physical requirements.
- 3LD3050-0TL13 shares the TL pole configuration and Siemens 3LD platform but drops to 16 A current rating. Useful for lower-power disconnect applications where the same actuator and mounting footprint is preferred across a machine line.
