Description
The ACI 142355 is a solid core, normally open (NO) current switch designed for reliable current sensing and equipment status monitoring in HVAC and building automation applications. With a wide sensing range of 0–250A, this switch is well suited for monitoring motors, fans, pumps, compressors, and other high-current loads commonly found in commercial and industrial HVAC systems.
Key Features
- Solid core design — conductor wire must be threaded through the sensing window for secure, stable installation
- Normally open (NO) contact output — closes upon detection of current flow above the setpoint
- Wide current sensing range: 0–250A
- Provides a dry contact output signal compatible with building automation systems (BAS), DDC controllers, and monitoring panels
- Compact, durable housing suitable for panel or DIN rail mounting environments
- Ideal for proof-of-flow and proof-of-operation applications
Typical Applications
- Motor run verification for fans, pumps, and compressors
- Equipment status monitoring in commercial HVAC systems
- Building automation and energy management integration
- Fault detection and alarm signaling
