Siemens 3SB50001NB01 is an iconic 22.5 mm industrial push button / signaling device (Siemens 3SB5 series) manufactured for Indian LT switchboards, motor control centers (MCC), and control desks. Rated for operational voltages up to 415V AC (50 Hz) and 10A thermal current (Ith), it strictly conforms to IS/IEC 60947-5-1 (AC-15: 4A at 240V, 2A at 415V).
Available with sleek plastic or heavy-duty metallic front rings, Siemens 3SB50001NB01 delivers IP65 / IP67 ingress protection compliant with IS/IEC 60529, effectively sealing the contact mechanism against humid monsoon environments, coal/cement dust, and oil mist.
Siemens 3SB50001NB01 supports modular snap-on contact blocks (1NO, 1NC, 1NO+1NC, 2NO, or 2NC) with silver alloy self-wiping contacts. The NC contact elements feature positive opening operation (IEC 60947-5-1 Annex K) for fail-safe machinery emergency tripping.
The push button 3SB50001NB01 is engineered for over 10 million mechanical switching cycles for momentary push buttons (300,000 cycles for latching/selector switches). It mounts securely in standard 22.5 mm punch holes with an integral anti-twist locating lug and rear locking nut.
Buy authentic Siemens 3SB50001NB01 push buttons directly from Electrihub India. Electrihub India provides genuine Siemens India stock, competitive volume rates, full 18% GST tax invoices for input tax credit, and fast Pan-India dispatch.
The Siemens 3SB50001NB01 belongs to the SIRIUS 3SB5 / 3SB3 22 mm modular pilot device range, and it installs into a standard 22 mm (22.3 +0.4/0 mm) round panel cutout, the global norm defined in EN/IEC 60947-1. Checking this cutout size before ordering avoids rework on an already-drilled control panel, and because the dimension follows an internationally recognised standard, panels designed in one country can be fitted with the 3SB50001NB01 sourced from another without modifying the enclosure.
The Siemens 3SB50001NB01 is rated at IP66 as a complete front-mounted unit (with IP20 on the rear terminal side), and the design is also rated up to IP67/IP69K on related SIRIUS variants, so it withstands dust, jetting water and washdown. This level of sealing is what determines whether the device can be specified for washdown areas, outdoor enclosures, dusty workshops or humid coastal sites, so it is one of the first specifications engineers in any country check when matching a pushbutton to its installation environment.
The Siemens 3SB50001NB01 is manufactured to EN/IEC 60947-1 and EN/IEC 60947-5-1, with UL 508 and CSA C22.2 No. 14 approvals plus a CE mark, so the same catalogue number can be specified on machinery shipped to the EU, North America, the Middle East and Asia-Pacific without a redesign. Holding recognised IEC, UL, CSA and CE approvals together (rather than just one regional mark) is what lets the same part number be specified on machinery and switchgear panels built for the EU, North America, the Middle East, Africa and Asia-Pacific, without needing a region-specific substitute.
The Siemens 3SB50001NB01 offers a rated insulation voltage of up to 400 V AC/DC and a rated operational current in the 3–10 A range at AC-15/DC-13 duty (exact figures vary by the fitted contact block, typically 1 NO, 1 NC or 1 NO+1 NC). Confirming the rated voltage, current and contact configuration against the control circuit it will switch is essential, since undersizing the contact block against the connected load is one of the most common causes of premature pushbutton failure in the field.
The Siemens 3SB50001NB01 is rated for an operating range of -25°C to +70°C, with a mechanical life of roughly 1,000,000 operating cycles, so it holds up in high-cycle machine-control and HVAC panel duty across hot, humid or cold-climate installation sites alike. This combination of climate range and cycle life is what allows the same push button to be deployed in cold-storage plants, standard factory floors and hot, humid outdoor installations across different climate zones without a separate temperature-rated variant.
