Blue Illuminated Momentary Push Button

The SIEMENS 3SU1102-0AB50-1FA0 is a 22 mm flush-mounted illuminated push button with a blue plastic head and bezel. It provides momentary action for control panels and machine interfaces. The unit carries a 1NO/1NC contact configuration rated at 10A @ 600V AC and 5A @ 600V DC. NEMA A600/R300 designation confirms suitability for heavy-duty pilot duty.

Industrial Control Panels Needing Visual Status

This switch suits panels where operators need clear visual confirmation of circuit state in harsh environments. The IP66, IP67, IP69 and IP69K ratings protect against high-pressure wash-down and dust ingress. NEMA 1, 2, 3, 3R, 4, 4X and 12 enclosures are supported. Buyers requiring maintained-action switches or non-illuminated operators should consider other types.

10 Amp Contact Capacity With Screw Terminals

The single operator handles control-circuit loads up to 10 amps at 600 volts AC or 5 amps at 600 volts DC. Screw terminals accept standard wiring for secure connections. The momentary mechanism returns automatically when released, limiting use to momentary signalling or interlock tasks rather than continuous power switching.

Questions about this item

What panel cut-out size is required for the 22 mm illuminated push button?

The operator needs a standard 22 mm panel cut-out for flush mounting.

Can the 1NO/1NC contacts switch a 600 V AC load rated at 10 A alongside legacy A600-rated starters?

Yes, the contacts carry a NEMA A600 rating at 10 A / 600 V AC and R300 at 5 A / 600 V DC.

How do I verify the blue LED illumination is functioning after wiring the screw terminals?

Apply control voltage; the blue flush head lights immediately and the momentary action returns on release.
