Illuminated Push Button 22 mm Blue

The SIEMENS 3SU1103-0AB50-1FA0 is a 22 mm illuminated push button with a blue flush plastic operator and a plastic bezel. It provides momentary action and a 1NO/1NC contact form rated at 10A @ 600V AC and 5A @ 600V DC. The unit carries NEMA ratings 1, 12, 2, 3, 3R, 4, 4X and IP ratings IP66, IP67, IP69, IP69K for harsh environments.

Screw Terminal Installation and Wiring

Installation uses screw terminal connections that accept standard ferrules or stripped wire for secure contact. The 22 mm mounting diameter fits standard panel cut-outs, but the plastic head and bezel require careful torque to avoid cracking. Miswiring the 1NO/1NC contacts is the most common error, so verify the circuit diagram before tightening terminals.

Sustained Load Behaviour

Under continuous operation the contact rating of 10A @ 600V AC and 5A @ 600V DC remains stable within the NEMA A600/R300 designation. The IP66, IP67, IP69 and IP69K seals prevent ingress during prolonged exposure to water, dust and high-pressure wash-down. Plastic materials meet CAS, REACH and WEEE 2012/19/EU substance restrictions for long-term compliance.

Questions about this item

How can I verify the blue 22 mm illuminated push button lights correctly after wiring?

Apply rated voltage to the full-voltage terminals; the blue lens should illuminate steadily while the momentary flush operator returns to its original position when released.

What components are included with the 3SU1103-0AB50-1FA0 and what must be sourced separately?

The package contains the illuminated operator head, plastic bezel, and 1NO/1NC contact block with screw terminals; mounting hardware, legend plates, and wiring are not included.

Which version should I choose if I need a blue 22 mm momentary push button with 1NO/1NC contacts and IP69K rating?

This specific model provides exactly that combination — blue flush operator, 1NO/1NC contacts, screw terminals, and IP66, IP67, IP69, IP69K protection in a single orderable part number.
