3SU1100-1HB20-1PG0, Siemens, EMERGENCY STOP button

3SU1100-1HB20-1PG0 is a control push button made by Siemens.

The description is based on specific source data, not just on general text for the whole category. For industrial control devices, a single character in the order code can mean a different contact, colour, voltage, return or mechanical design.

Function and principle

A control push button is used for manually entering commands to a machine or a safety circuit, depending on the specific variant. Before ordering, check the mechanical function, contacts, colour and mounting dimension.

Typical applications

The product is intended for control panels, switchboards, machines and process equipment according to its specific function. When designing the application, the working environment, operating frequency, mechanical stress and electrical parameters of the connected circuit must be taken into account.

Technical specifications

Mounting and wiring

Before mounting, compare the mechanical dimension, compatible series and electrical wiring. After installation, carry out a functional test of all positions or contacts.

How to choose the right variant

Compare the exact order code, mechanical design and electrical parameters.

Compatibility and connection

For modular control devices, check the compatibility of the head, contact blocks, light block, holder and accessories. For complete devices, check the mounting dimension and electrical wiring. When replacing an original part, use the complete order code as the basis.

Operation, inspection and service

After mounting, carry out a functional test of all positions and contacts. During regular maintenance, check the mechanical fastening, connection condition and any wear of the operating mechanism. When replacing, always note the exact order code of the original part.

Source of technical data

The technical data of this product are taken only from the TECHNOLINE source export; the EMAS catalogue was not used for a product of another manufacturer.

If a parameter is not listed in the table, it was not clearly documented in the available sources and has not been assumed in the description.

FAQ

What kind of product is 3SU1100-1HB20-1PG0?
3SU1100-1HB20-1PG0 is a control push button made by Siemens. The exact design is summarised in the technical table.

How to verify the correct variant of 3SU1100-1HB20-1PG0?
Compare the complete order code, mechanical design and all parameters in the table. Similar series may differ in contacts, return, voltage or mounting.

What should be checked before ordering?
Compare the exact order code, mechanical design and electrical parameters.

How to mount the product correctly?
Before mounting, compare the mechanical dimension, compatible series and electrical wiring. After installation, carry out a functional test of all positions or contacts.

Why is selecting by photo alone not enough?
Several electrically different variants may look the same. The order code and catalogue specification are decisive.

How to check the electrical wiring?
Check the NO/NC contacts, rated voltage and connection type according to the specific variant. Carry out a functional test after mounting.

Can another variant of the same series be used?
Yes, but only if both the mechanical fastening and the electrical function match. Confirm the interchange using the parameters of both order codes.

What is important during service or replacement?
Note the exact order code of the original part, the contact configuration and the mounting method. This significantly reduces the risk of an incorrect replacement.

What data is the description based on?
For EMAS products, data from the EMAS Product Overview Edition 57 (30.06.2026) and data from the TECHNOLINE source export are used. For other manufacturers, only documented data from the export.

What to do if a parameter is not listed in the table?
The parameter was not clearly documented in the available sources. In that case, verify it in the documentation of the specific product before designing the application.
