ABB Phase, Voltage Monitoring Relay, 1, 3 Phase, SPST, 185 → 265V ac, DIN Rail

This monitoring relay from ABB helps detect undervoltage and overvoltage in your circuit to keep your equipment protected against electrical damage. Its wide voltage measuring ranges of 185 to 265V AC and 320 to 460V AC make it suitable for use in low-power and medium-power systems. A maximum measuring cycle time of just 80ms means it quickly senses potential hazards. The yellow LED indicator lets you know when the output relay is energised, making it easy to monitor its operating status.

• Long mechanical service life of up to 30 million cycles for long-lasting performance
• Short time delay of 500ms for a quick reaction
• Terminals have an IP20 rating, meaning they're finger-safe and protected against tools and wires larger than 12mm in size
• Broad operating temperature range of -20°C to +60°C for use in demanding environments

• Refrigeration systems
• Hydraulic pumps
• Compressors

This monitoring relay is designed for mounting on a standard DIN rail for ease of installation. For versatility, you can mount it in any position.
