Siemens 3RN2 Series Monitoring Relay, 24V Supply Voltage, 1A Contact Current - 3RN2000-2AA30

This monitoring relay is a Compact evaluation unit designed for thermistor motor protection in control panels. It operates from a 24V AC/DC supply and provides a single changeover contact with automatic reset and a tripped LED indication. The device mounts on a 35mm DIN rail using snap‑on or screw fastening and is intended for industrial installations requiring thermal sensing via bimetallic temperature switches.

Features and Benefits:

• 0.30W power loss reduces energy draw in continuous operation
• -25°C to 60°C operational range supports wide ambient conditions
• 1A DC contact current enables control of low‑power circuits
• Spring‑loaded terminals allow quick conductor insertion
• 5A switching element withstands transient load conditions

Applications

• Suitable for motor thermistor protection installations
• Ideal for control panels in industrial environments
• Used with bimetallic temperature switches for monitoring
• Can be used where Compact DIN rail mounting is required
• Suitable for systems needing automatic reset after trip

What surge immunity does the unit provide?

It offers 4kV surge voltage resistance and withstands conductor-to-earth surge up to 2kV.

How long will the relay switch contacts endure electrically?

At 24V AC under AC-15 duty the contact endurance is typically 100,000 operating cycles.

What conductor sizes are accepted by the terminals?

Solid conductors 0.5…4 mm² and finely stranded with end ferrules 0.5…2.5 mm² are supported.
