Honeywell CSP-NO-A-150A Adjustable Split Core N/O Mini Current Switch 0.5-150A

The Honeywell CSP-NO-A-150A Mini Current Switch is used in measuring electrical current within HVAC systems. Due to its split-core construction, it can be easily wrapped around existing conductors without having to interrupt service. Having a normally open output, the switch turns on when the current flow is over a set limit within the 0.5-150A range. This part is useful for obtaining dependable operation, simple installation, and precise current measurement. It is widely applied to HVAC equipment to sense motor running, check heating element on or other electrical loads, and optimize the equipment’s performance and maintenance.
