Description
The ACI 142353 is a split-core, normally open (NO) current switch designed for non-invasive current sensing and load monitoring in HVAC and building automation applications. Its split-core design allows installation directly around an existing conductor without interrupting the circuit, making it ideal for retrofits and new installations alike.
Key Features
- Split-core construction for tool-free, non-invasive installation on existing wiring
- Normally open (NO) output configuration
- Wide sensing range: 0–250A
- Detects motor run status, fan operation, pump activity, and other current-carrying loads
- Compact, durable housing suitable for panel or field mounting
- Ideal for integration with building automation systems (BAS) and energy management systems
Typical Applications
- HVAC fan and motor proof-of-operation verification
- Pump and compressor current monitoring
- Building automation and DDC control systems
- Energy management and load monitoring
- Fault detection and equipment status feedback
