Siemens 3ZY1121-2BA00 is a SIRIUS removable 2-pole terminal designed for control-circuit connections in industrial standard mounting rail enclosures. Featuring a push-in spring-loaded design, it allows fast, tidy and dependable wiring with conductor sizes up to 2 x 1.5 mm², making it a practical choice for compact panel assemblies where efficient installation matters.
Built for straightforward integration with compatible SIRIUS devices, this terminal supports solid and finely stranded conductors and provides a secure connection within an IP20-rated format. Its narrow 7.5 mm width helps save space inside the enclosure while maintaining convenient access for organised wiring layouts.

What is this removable terminal used for?
This component is a 2-pole removable terminal designed for control circuit connections on compatible SIRIUS devices installed in an industrial standard mounting rail enclosure. It provides a practical way to connect and disconnect wiring during installation or replacement.
Is this a plug-in or fixed terminal?
It is a removable terminal, which means it can be detached from the device rather than being permanently fixed in place. This can help simplify panel assembly and wiring changes.
How many connection poles does it have?
It has 2 poles, making it suitable for control circuit applications where a compact two-connection terminal is required.
What connection method does it use?
It uses a spring-loaded push-in connection design. This allows suitable conductors to be inserted quickly while maintaining a secure electrical connection.
What conductor sizes can be connected?
The terminal is designed for conductors up to 1.5 mm², depending on conductor type. In general, it supports solid conductors from 0.5 to 1.5 mm² and finely stranded conductors from 0.5 to 1.5 mm², with some variation depending on whether ferrules are used.
Can it accept both solid and stranded wires?
Yes. It is suitable for both solid and finely stranded conductors, provided the wire size falls within the stated connection range for the terminal.
Can ferruled conductors be used with this terminal?
Yes, finely stranded conductors with core end processing can be used. For this style of conductor, the supported range is up to 1.0 mm² according to the available datasheet information.
Can more than one conductor be connected in the same terminal point?
Yes. The terminal is designed to accept up to two conductors per connection point within the permitted conductor size range, which can be useful in compact control wiring layouts.
What is the ingress protection rating?
The terminal has an IP20 protection class. This means it is intended for use inside suitable enclosures where protection against accidental contact is managed as part of the overall installation.
How much panel space does this terminal take up?
The stated width is 7.5 mm, so it is a compact option where space efficiency is important in a control panel or rail-mounted assembly.
Is this suitable for rail-mounted industrial equipment?
Yes. It is intended for SIRIUS devices in industrial standard mounting rail enclosures, so it is suited to organised rail-based control assemblies.
Where is this terminal typically used in an electrical assembly?
It is typically used in control circuit wiring on compatible industrial devices, especially where a neat, removable, push-in terminal arrangement is preferred. In listings or documentation, it may also be referenced as 3ZY1121-2BA00.
- Creating detachable control circuit connections on Siemens SIRIUS devices mounted in industrial standard DIN rail enclosures.
