All variants share the same 3RT2015 base number, S00 frame size, 7 A contact rating, and chassis/DIN mounting. Differences appear in coil voltage and, for some entries, coil power draw and packaging.
Why the Alternates Are Catalog-Peers
- 3RT20151AG62 differs only in auxiliary function (NC instead of NO) and coil voltage (110 VAC). Coil power is higher at 31.7 VA; must-operate rises to 93.5 VAC. Both are S00 frame, 7 A, chassis/DIN mount.
- 3RT20151AK61 carries the same auxiliary (1NO) but a 120 VAC coil. Must-operate is 96 VAC; coil power is 26.4 VA, matching the seed. Packaging remains bulk.
- 3RT20151AN61 shifts to 200 VAC coil with 170 VAC must-operate, otherwise matching seed specs: 26.4 VA coil power, bulk encapsulation, 1NO auxiliary, chassis/DIN mount.
- 3RT20151AP61 uses a 240 VAC coil (must-operate 192 VAC) at 26.4 VA. Packaging style differs (Box vs. Bulk); auxiliary is 1NO. Chassis/DIN mount retained.
- 3RT20151AU61 targets higher coil voltage (277 VAC, must-operate 235.5 VAC) with 31.7 VA coil draw. Packaging is Box; auxiliary is 1NO; mounting is chassis/DIN.
- 3RT20151AR61 specifies 440 VAC coil (must-operate 374 VAC) at 31.7 VA. Contact rating, form, and mounting match the seed family. Packaging is Box.
- 3RT20151AV61 advances to 480 VAC coil (must-operate 408 VAC). Coil power is 31.7 VA; packaging is Box; auxiliary is 1NO; mounting is chassis/DIN.
- 3RT20151AT61 targets 600 VAC coil circuits (must-operate 510 VAC) with 31.7 VA coil. All shared spec keys (7 A, 3PST-NO, chassis/DIN, 35 ms, 25–60°C) align with the seed.
All alternates are catalog-screen peers under the same 3RT2015 base number family. The reader must perform their own suitability assessment for each application.
