Veris Industries H-735 Switch

The Veris Industries H-735 (also known as the H735) is a high-performance adjustable current switch integrated with a 24VAC/VDC SPST relay designed for comprehensive building automation system (BAS) control. This solid-core current sensor functions as a dual-purpose unit, allowing contractors to manage motor start/stop control while simultaneously monitoring real-time load status. With a continuous amperage sensing range of 1 to 135A, the H-735 is the industry standard for detecting belt loss, coupling shear, and motor failure in HVAC fan and pump applications.

The internal SPST command relay and the current status switch operate independently, effectively replacing the need for separate differential pressure switches or multiple electromechanical devices. The unit features a multi-turn adjustment potentiometer for precise setpoint calibration and high-visibility LED indicators for relay status and current sensing. Built for demanding mechanical rooms, the Hawkeye H735 utilizes induced power from the monitored conductor for the sensor side, ensuring simplified two-wire installation for the status output.

Key Benefits

• Integrated Relay and Sensor: Combines a 5A rated command relay and an adjustable status sensor in a single housing to save enclosure space.
• Accurate Status Monitoring: Optimized for positive status detection, identifying drive belt slips or mechanical failures where current drops by up to 50%.
• Simplified Wiring: Features polarity-insensitive status outputs and a small footprint for easy retrofitting into tight starter enclosures.
• High Current Capacity: Effectively monitors AC loads up to 135 Amps; for higher loads, it is compatible with standard 5A current transformers.

Common Questions

Can the H-735 monitor loads below 1 Amp?
Yes. To monitor sub-1A currents, wrap the conductor multiple times through the solid-core center hole. The sensor will read the actual current multiplied by the number of passes.

Does the relay require external power?
Yes. While the current sensor is self-powered by induction, the integrated relay coil requires an external 24VAC or 24VDC power source to operate.

What is the difference between the H-735 and H735?
There is no difference; they are functionally identical parts used interchangeably in technical submittals and electrical schematics.
