Siemens Monitoring Relay, SPDT, DIN Rail, 24V ac 24 V dc

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.

• 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

• 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

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

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

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