The Siemens 3RN2010 2CA30 is a precision voltage monitoring relay designed to protect motor windings by sensing thermistor outputs and switching via a single-pole, double-throw (SPDT) contact. Housed in a slim 17.5 mm DIN-rail-mount enclosure, it operates reliably across a broad temperature range (–25 °C to +60 °C) and accepts both 24 V AC and DC supplies. Its spring-type terminals ensure quick, secure wiring, while the 3RN2 series pedigree delivers consistent performance for industrial motor protection applications.

Why Choose the Siemens Monitoring Relay?

Choosing this relay offers unmatched reliability and efficiency in motor temperature protection. Its direct temperature sensing enables early fault detection under demanding conditions—heavy starts, frequent switching or poor cooling—eliminating the need for motor oversizing and enhancing uptime. With auto-reset, dual status LEDs, and international certifications, it blends operational safety and cost-effective installation into one compact package.

Product Core Features Include:

  • Thermistor motor temperature protection for early fault detection
  • SPDT contact configuration for versatile control schemes
  • 24 V AC/DC supply compatibility for varied installations
  • DIN-rail mounting in a 91.6 × 17.5 × 100 mm housing for space-saving panel layouts
  • Wide operating temperature range (–25 °C to +60 °C) for harsh environments
  • Spring terminal connections for rapid, maintenance-free wiring
  • Motor voltage sensitivity tuning for precise monitoring thresholds.
