Eaton Voltage Monitoring Relay, 400V AC Maximum Voltage, 50ms Measuring Cycle - EMR6 Series - 184778 EMR6-W400-M-1
Protect your equipment from a state of over-voltage or under-voltage using this voltage monitoring relay from Eaton. You can use it to monitor phase failures and phase sequences in 3-phase motors, making it a versatile choice. Mounting it is simple as the DIN rail design means you can clip it on without any tools. Thanks to a wide operating temperature range between -20°C and +60°C, this unit can withstand challenging environments. The LED indicators let you observe its operating status for quick configuration. Use this relay to monitor voltage conditions in your electrical and mechanical industrial applications.
• Adjustable reset delay/off-delay time between 0.1 and 30s for versatility
• Measuring cycle of 50ms for rapid operation
• Temperature error rating of 0.06%/°C to accommodate temperature fluctuations for enhanced accuracy
• Maximum voltage sensed of 400V AC for safe use in powerful systems
How durable is this relay?
This device has an electrical lifespan of 10,000,000 operations so you can rely on it for long-term performance. This is further enhanced by its mechanical durability rating of 30,000,000 cycles.
