ABB Monitoring Relay 3 Phase DPDT DIN Rail Mount 720V AC CM-PFS 1SVR730824R9300 CM-PFS.S

ABB 1SVR730824R9300 CM-PFS.S monitoring relay is designed for protecting three-phase electrical circuits against phase faults and voltage anomalies. It features a DPDT (double-pole, double-throw) contact configuration that controls two circuits with ON-ON or ON-OFF-ON switching capabilities. The relay operates on a 720V AC supply voltage and is mounted easily on standard DIN rails without tools.

The unit measures compactly at 85.6mm height, 22.5mm width, and 103.7mm length, making it space-efficient for control panels. Its silver-nickel contacts ensure low resistance and reliable connectivity, suitable for industrial applications requiring swift and accurate monitoring.

Equipped with a fast response of 500 milliseconds, the relay promptly detects phase faults to safeguard electrical equipment. The mechanical lifespan is rated at 30 million operations, promising long-term robustness in demanding environments.

Connection terminals use screw-type double-chamber cage technology, offering secure and reliable wiring connections. The IP20 rating provides adequate protection against solid objects, while its operating temperature range from -60°C to +60°C allows deployment in variable climatic conditions.

An important feature includes visible status indication via LEDs on the front panel. A yellow LED shows output relay status, while a red LED signals fault detection, enabling straightforward maintenance and monitoring.

Applications for this Monitoring Relay include process automation, packaging machinery, heating and air conditioning systems, and compressors in industrial settings. Manufactured in Germany, it complies with RoHS standards, ensuring environmental safety.

Compact dimensions of 85.6mm (H) x 22.5mm (W) x 103.7mm (L) enable space-saving installation. Double-pole, double-throw contact configuration allows control of two circuits. Silver-nickel contacts provide low electrical resistance and reliable connection.

Fast 500ms response time for prompt fault detection. High mechanical service life of 30 million cycles. Screw terminal double-chamber cage connections ensure secure wiring. IP20 rated enclosure suitable for indoor use. Tool-free DIN rail mounting for easy installation.

Operating temperature range: -60°C to +60°C. LED indicators for output status and fault messages. Explore the full range of ABB electrical relays and monitoring devices for industrial, HVAC, manufacturing, and automation applications on EnvMart.
