Siemens SIRIUS Innovations Series Auxiliary Switch, 2 NC Contacts, 10A Current - 3RV2901-1C

This auxiliary switch provides instantaneous, lateral indication of circuit-breaker contact status for industrial control panels. It is a plug-in device with screw terminals designed to mount alongside compatible circuit-breakers and delivers switching functionality across AC and DC systems while operating in typical electrical enclosures.

Features and Benefits:

• 10A rated operational current for AC-12 provides robust switching capability
• 250V DC and 690V AC contact voltage supports diverse circuits
• Rated insulation voltage 690V enhances dielectric separation
• Operates between -20°C and 60°C for standard industrial environments
• Screw-terminals and plug-in fastening allow straightforward installation

Applications

• Suitable for remote status signalling in motor control systems
• Used with circuit-breakers sized S00, S0, S2, S3 for indication
• Ideal for auxiliary monitoring in distribution panels
• Can be used for interlock feedback in automated switchgear

How many contacts does it provide for signalling?

It provides two normally closed instantaneous auxiliary contacts.

What conductor sizes can be connected to the terminals?

Solid or stranded conductors from 0.5…2.5 mm² are acceptable, including finely stranded with end ferrules.

Which protection and safety recognitions does it hold?

It is certified to CE, UL, CCC, EAC and UKCA standards.

What ingress protection and touch safety are specified for the front?

The front meets an IP20 ingress rating and finger-safe touch protection per IEC 60529.
