SIEMENS SIRIUS ACT 3SU1400-1AA10-1LA0 kosketinmoduuli, 1 NO, ruuviliitin, pohja-asennus

The SIEMENS 3SU1400-1AA10-1LA0 contact module stands out with its robust floor-mounting design and reliable screw terminals, making it a solid choice for industrial control circuits that demand a single normally open contact. Part of the SIRIUS ACT series, it is engineered for straightforward integration and long-term dependability.

Highlights

• 1 NO contact configuration for standard switching tasks
• Screw terminals accept solid or stranded conductors from 0.5 to 2.5 mm² (20–14 AWG)
• Rated insulation voltage 500 V AC/DC and impulse withstand 6 kV
• Operational current up to 6 A at AC-15 (230 V) and 10 A at DC-13 (24 V)
• Silver alloy contacts ensure consistent performance over 10 million electrical and mechanical cycles

In daily use

Designed for floor mounting, this module fits neatly into control panels and operator stations. The screw terminal connection provides a secure, maintenance-friendly wiring method, while the wide operating temperature range from -25 to +70 °C supports use in demanding environments. The IP20 terminal protection is typical for enclosed installations, keeping wiring safe from accidental contact.
