Siemens 3RH2911 Series Auxiliary Switch, DPDT Pole and Throw Configuration, 10A Contact Current - 3RH2911-1LA11

This auxiliary switch snaps onto the front of contactors and relays to provide mirrored signalling and positively driven switching for control circuits. It is designed for use with specified contactor families and offers screw-terminal connections with cable entry from the top. The unit operates across a wide ambient range and meets multiple safety and regional approvals for industrial control applications.

Features and Benefits:

• 1NO1NC contact arrangement delivers distinct signalling paths
• 10A current rating enables switching of moderate control loads
• 690V rated insulation supports higher-voltage AC systems
• -25°C to 60°C operating range suits varied installations
• Mechanical durability 10M cycles ensures long-term operational life

Applications

• Suitable for mounting on 3RT2 contactors and 3RH2 relays
• Used with control circuits requiring mirror contact functionality
• Ideal for auxiliary signalling in industrial motor control systems
• Can be used where screw-terminal connections are required
• Suitable for installations needing Snap-on front-side mounting

What type of electrical connection does it use?

It uses screw-type terminals compatible with solid or stranded conductors up to 2.5 mm².

How does it perform under repeated operation?

Mechanical service life is specified at 10 000 000 operating cycles with electrical endurance up to 200 000 cycles at AC-15, 230 V.

What approvals support its use in certified systems?

It is approved to CCC, cULus, EAC and UKCA standards.

Can it switch DC control voltages reliably?

Contact ratings include DC operation down to 17 Vdc with specified currents across various DC voltage levels.

What short-circuit protection is recommended for the auxiliary circuit?

A 10 A fuse link of type gG with 690 V, 1 kA capability or a 10 A, 0.4 kA characteristic miniature circuit-breaker is specified.
