The ACI 101792 is a normally closed (NC) pressure switch designed for HVAC and building automation applications where precise differential pressure monitoring and system protection are essential. With a setpoint range of 1.25 to 12 inches water column (WC) and a manual reset (M/R) mechanism, this switch provides dependable overpressure protection and requires deliberate operator intervention before resuming operation — helping prevent repeated automatic restarts that could mask underlying system issues.
Key Features
- Pressure range: 1.25–12″ WC (inches water column)
- Normally closed (NC) contact configuration
- Manual reset (M/R) operation for added safety and control
- Designed for HVAC, building automation, and air handling applications
- Compact, field-installable design for easy integration
Application
The ACI 101792 pressure switch is well suited for monitoring duct static pressure, filter status, fan proving, and airflow verification in commercial and light industrial HVAC systems. The manual reset feature ensures that technicians must physically inspect and clear a fault condition before the system is allowed to restart, improving safety and system longevity.
