Veris Industries H-948 Current Switch

The Veris Industries H-948 is a professional-grade split-core current switch engineered to provide simultaneous monitoring and control of AC motor loads. Designed for contractors who value space-saving efficiency, this device integrates a 2.5-135A adjustable setpoint sensor with an onboard 24V AC/DC command relay. This combination allows for independent start/stop control and positive status verification of fans, pumps, and motors with a single installation point. The unit is powered directly from the monitored conductor through current induction, reducing field wiring complexity and minimizing hardware footprint in crowded starter enclosures.

Ruggedly built for industrial building automation (BAS), the H-948 features a 20-turn potentiometer for precise trip point adjustment, ensuring sensitive detection of belt loss, coupling shear, or motor failure. The split-core current sensor housing enables easy retrofitting without disconnecting high-voltage conductors. With its polarity-insensitive relay-combo switch and diagnostic LEDs for status monitoring, the H-948 is the technical standard for reliable load status and equipment automation in commercial HVACR environments.

Key Benefits

• Dual Functionality: Combines a command relay and status sensor into one device to reduce SKU count and labor time.
• Adjustable Range: Provides a versatile sensing window of 2.5 to 135 Amps for compatibility with a wide range of motor sizes.
• Split-Core Convenience: Allows for fast installation around existing cables without interrupting the electrical circuit.
• Integrated Relay: Features a high-quality SPDT relay rated for 8A at 250VAC, ideal for direct motor control.
• Remote Monitoring: Enables building controllers to determine real-time equipment status via induced current sensing.

Common Questions

• How do you calibrate the setpoint for belt loss detection? With the motor running under normal load, turn the adjustment screw until the status LED closes, then dial it slightly further to ensure the switch tips if the load drops below normal operating amperage.
• Does this require an external power supply for the sensor? The current switch sensor is self-powered via induction, but the command relay requires a separate 24V supply to operate the coil.
• Can I use this for loads below 2.5 Amps? Yes, you can wrap the monitored conductor through the sensor window multiple times to effectively "multiply" the current detected by the unit.
