Siemens 3SB02-TTI Press Test Transformer Type 120V

Siemens 3SB02-TTI is a 22 mm pilot-device that combines a press-to-test transformer with a push button for 120 V operation, designed for front-mount installation in standard 22 mm control panels. This variant belongs to the Siemens 3SB02 family of 22 mm pilot devices and provides an integrated test function for signaling circuits, enabling quick verification of the associated indicator at 120 V from the button itself. The compact front-face footprint supports modular panel applications in automation and machinery controls where space is at a premium. By preserving the press-to-test capability within the 3SB02 line, the 3SB02-TTI offers an integrated solution for signaling and testing workflows in industrial control systems. For exact electrical specifications, compatibility notes, and installation instructions, consult the official Siemens datasheet for the 3SB02-TTI Transformer Type 120 V to ensure proper integration with your control system.
