Veris Industries H-708 Switch

The Veris Industries H-708 Hawkeye series is a high-performance solid-core current switch designed to provide reliable status detection for building automation systems. Built as a direct solution for replacing legacy E112-705-DC and E112-708 units, the H-708 features an adjustable trip point from 1 to 135A, allowing for precise calibration in the field. This sensor is specifically engineered to detect mechanical failures such as belt loss or coupling shear by monitoring the amperage drop that occurs when an HVAC motor loses its load. Its compact NEMA 1 enclosure fits easily into tight electrical panels, and the sensor power is induced directly from the monitored conductor, eliminating the need for an external power supply. A built-in status LED provides immediate local indication, simplifying the setup process for fan and pump status monitoring. With a 1.0A @ 30 VAC/DC output rating and a frequency range of 50/60 Hz, the H-708 is an essential component for verifying HVAC motor operation in both retrofit and new construction projects.

• Direct Replacement: Seamlessly replaces E112-705-DC and E112-708 models without hardware modification.
• Precise Detection: Accurately identifies belt loss and coupling shear in motors from 1/5 to 100 HP.
• Self-Powered: Induced current from the monitored wire powers the device, reducing wiring complexity.
• Easy Calibration: Features integrated status LEDs for visual confirmation of the trip point during installation.
• Flexible Amperage: Wide 1-135A adjustable range accommodates a variety of fixed-load applications.

How do I monitor a load that pulls less than 1 Amp?
To monitor currents below 1A, wrap the conductor through the center hole multiple times. The sensor will detect the actual current multiplied by the number of turns.

Is the H-708 compatible with high-current industrial motors?
The H-708 supports up to 135A directly. For applications exceeding this amperage, use a 5 Amp current transformer (CT) and run the CT secondary through the H-708 window.

Can this switch be used on VFD applications?
Yes, the H-708 is commonly used to monitor the output status of Variable Frequency Drives to verify motor operation.
