Honeywell CSP-C-A200-001/U Adjustable Current Switch. All of these sensors have a solid-state output with an adjustable or fixed trip point (setpoint). These current switches should be used in applications in which a inGo/No Going current switch is required. The current switches can be used to monitor devices with a maximum continuous operating current of up to 250 Amps. These current switches do not need to be externally powered, since the power for the switch is induced from the conductor being monitored. The split core switches are ideal for retrofit or existing installations, since it is not necessary to power down the unit and disconnect any wires during the installation process. Solid core switches are extremely easy to install, they are an excellent choice for new installations.
