Siemens 3RT20162AN22 Mini Contactors
The 3RT20162AN22 is a Siemens Size S00 (S00) electromechanical contactor in the 3RT2016 family, fitted with a 220VAC coil and one NC (normally closed) auxiliary contact on a spring-clamp termination block. The unit delivers 9 A nominal contact current across three NO power poles and is packaged in a box-style enclosure for chassis or DIN-rail mounting.

Catalog family and coil voltage peers
The 3RT2016 series uses a suffix-based variant code where the fifth character distinguishes coil voltage. All members share 9 A power poles, spring-clamp terminations, the same Size S00 housing, and 35 ms operate/release timing.
- 3RT20162AN21 — 220VAC coil, 1NO auxiliary contact; identical coil power (24.3 VA) and must-operate voltage (187 VAC).
- 3RT20162AP62 — 240VAC coil, 26.4 VA inrush; must-operate shifts to 192 VAC.
- 3RT20162AP02 — 230VAC coil, 24.3 VA; must-operate 195.5 VAC.
- 3RT20162AV02 — 400VAC coil, 24.3 VA; must-operate 340 VAC.
- 3RT20162AD02 — 42VAC coil, 24.3 VA; must-operate 35.7 VAC.
- 3RT20162AK62 — 120VAC coil, 26.4 VA; must-operate 96 VAC.
- 3RT20162AB02 — 24VAC coil, 24.3 VA; must-operate 20.4 VAC.
- 3RT20162AH02 — 48VAC coil, 24.3 VA; must-operate 40.8 VAC.
Selection notes
- Coil voltage determines must-operate threshold; ensure control-circuit voltage matches or exceeds the stated must-operate value before energizing.
- The 1NC auxiliary contact pair is suitable for interlock or status-feedback duty; verify contact rating against the intended auxiliary load.
- Spring-clamp terminations reduce installation time but may impose limits on conductor size or strand class in some panel-builder practices.
- Operating temperature window spans 25°C to 60°C; above 25°C thermal margin decreases; specify accordingly for warmer enclosure environments.
- The AN22 primary variant carries a 220VAC coil; peers with 120VAC or 240VAC coils (AP62, AK62) draw slightly higher coil power and shift must-operate voltage proportionally.
FAQ
What does the spring-clamp terminal style mean for field wiring? Spring-clamp contacts allow tool-free conductor insertion and vibration-resistant clamping; ferruled stranded wire is typically recommended for reliable connection.
Can the 3RT20162AN22 be mounted on a standard 35mm DIN rail? Yes — the specs list both chassis mount and DIN rail as approved mounting types for this size S00 device.
How does the 3RT20162AN21 differ from the 3RT20162AN22? The AN21 carries a 1NO (normally open) auxiliary contact, while the AN22 carries a 1NC (normally closed) auxiliary contact; all other recorded specifications are identical.
