Siemens SIRIUS ACT 3SU11 Series Panel Mount Momentary Push Button Switch, Red Round Actuator, SPDT, 22 mm 3SU1150-0AB20-1FA0

Siemens 3SU1150-0AB20-1FA0 is a high-quality push button switch from the SIRIUS ACT 3SU11 series designed for panel mounting in industrial and automation systems. It features a red, round, flat actuator that offers momentary switch operation ideal for start/stop control circuits and other machine interface applications. The switch provides a Single Pole Double Throw (SPDT) contact configuration with 1 normally open and 1 normally closed contact to enable versatile control logic.

The switch is engineered to fit a standardized 22 mm cutout size and mounts securely onto control panels using a panel mount configuration. It supports a robust operating voltage of up to 500 V AC and DC, suitable for various electrical environments, and can handle a contact current of 10A. The device is equipped with screw terminals ensuring reliable and easy electrical connection.

Its compact form factor with dimensions of 71.7 mm length, 40 mm height, and 30 mm width makes it fitting for tight spaces while maintaining operational ergonomics. The push button switch is rated for operation in ambient temperatures ranging from -25°C to 70°C to endure various industrial climates.

This non-illuminated push button switch does not include legend markings, which offers flexibility for custom labeling in application contexts. It is manufactured in Germany, assuring high build quality and durability. Siemens emphasizes sustainability with this model by implementing extended product life and low carbon manufacturing processes.
