Veris Industries H-120 Current Switch

The Veris Industries H-120 Current Switch is a high-performance, 2-in-1 AC current monitoring solution designed for professional HVAC and building automation systems. This unit combines a fixed-threshold current sensor and a robust 20A SPST command relay into a single, compact housing, significantly reducing installation labor and control panel footprint. Engineered for monitoring fractional HP motors, the H-120 features a low 0.1A turn-on threshold, making it capable of detecting even the smallest loads. The integrated relay combination series design allows technicians to connect the contacts directly to the load, providing simultaneous start/stop control and status feedback. With its 1/2-inch nipple mount, it installs directly into any standard conduit knockout. This NEMA 1 rated device is suitable for plenum applications, ensuring reliable operation for exhaust fans, unit ventilators, and pump control workflows where high-amperage switching and precise current detection are non-negotiable for project success.

• Space-Saving Design: Eliminates the need for a separate relay and sensor, freeing up valuable space in tight electrical enclosures.
• Versatile Mounting: Features a 1/2-inch threaded nipple for fast, secure attachment to standard knockouts.
• Low Current Sensitivity: Detecting loads as low as 0.1A ensures reliable status monitoring for high-efficiency, small-load equipment.
• High Power Capacity: Supports resistive loads up to 20A and motors up to 2HP, providing broad compatibility across commercial HVAC equipment.
• Visual Verification: Integrated LED indicator provides immediate status of the relay coil for faster commissioning and troubleshooting.

Can the H-120 be used with variable frequency drives (VFDs)?
The H-120 is designed for 50/60 Hz applications. For monitoring loads on the output side of a VFD, we recommend verifying the frequency range to ensure accurate current detection.

Is this switch suitable for plenum installations?
Yes, the H-120 features a NEMA 1 rated housing that is approved for use in plenum spaces, making it ideal for ceiling-mounted fan coils and air handlers.

Does the current switch require an external power supply?
The current sensor portion is self-powered via induction from the monitored conductor, while the relay coil requires a 24 VAC/DC source for operation.
