Siemens 3SB3400-1PE Integrated Lamp Module

Siemens 3SB3400-1PE is a 22 mm Signum actuator/indicator module with an integrated LED lamp holder, finished in white for panel mounting in control cabinets. It operates from 24 V AC or DC (50/60 Hz) and houses a built‑in LED light source, so no separate bulb is required. The unit provides one lampholder and uses screw-terminal wiring for secure, compact connections in constrained panel layouts. Electrical ratings include an insulation voltage of 250 V, a pollution degree of 3, and IP40 protection, with mounting integrated into the device body. This white LED indicator is suitable for status signaling in automation and machine‑control applications, such as indicating process states, Start/Stop conditions, or alert signals, where a compact, maintenance‑friendly indicator is preferred. The 3SB3400-1PE is designed to integrate with Siemens automation components, delivering a ready‑to‑install illumination solution within a single, low‑profile module.
