ABB Phase Monitoring Relay, 16mA Current Rating, 250V AC Operational Voltage - 1SVR730824R9300 CM-PFS.S


Protect your electrical circuits from damage due to phase faults with this monitoring relay from ABB. The unit has a double-pole, double-throw configuration, which means that it can control two circuits in two or three positions (ON-ON or ON-OFF-ON). Its silver-nickel contacts are conductive and have low electrical resistance, so they deliver a reliable connection. As the relay is sensitive to phase and voltage faults and has a swift response time of 500ms, it can trigger a response before the fault damages your circuit.

Features & Benefits


• Compact dimensions of 85.6 (H) x 22.5 (W) x 103.7mm (L) for space-saving installation
• Long mechanical service life of 30,000,000 cycles
• Screw connections with double-chamber cage connection terminals use a single screw to open and close both cages
• Designed for tool-free DIN rail mounting

Applications


• Process and packaging facilities
• Heating and air conditioning systems
• Compressors

How can I see the status of this relay?


This status of this monitoring relay is indicated by the two LEDs on the front of the unit. The yellow LED gives you the status of the output relays, while the red LED displays fault messages.
