|---|---|---|---|---|
| FFF Compatibility | Mounts to the exact same collar but utilizes tool-less spring-type terminals rather than screw terminals, requiring different wire termination.Identical overall physical dimensions and mounting footprint for 22.5mm front-plate collars.Provides the exact same SPST-NC contact arrangement and electrical ratings. | While it fits on the same standard 3-way or 4-way collar, the body has double the width/contact depth and more terminal connection points.Slightly deeper/wider body but conforms to the same series modularity and mounting pitch.Contains the required SPST-NC functionality (plus an extra, optional NC contact) and shares the identical 10A @ 500VAC rating. | ||
 AI Summary | 3SU1400-1AA10-1CA0 by Siemens: Configurable Contact Block SPST-NC 10A @ 500VAC. | This is the direct spring-terminal sibling of the queried part, retaining the same SPST-NC circuit configuration and electrical ratings while offering a tool-less, vibration-resistant termination style. It serves as a highly reliable, near-drop-in alternative.
| This sibling variant expands the contact configuration to 2 NC contacts while retaining the screw-terminal style and front mounting. It is ideal if you have extra physical depth in the enclosure and want to use the same wiring method.
