SETRA CSCGFN015NN Digital Current Switch

SETRA CSCGFN015NN Digital Current Switch is a compact, split‑core clamp device designed for real‑time motor and load monitoring in HVAC and industrial applications. It provides a fixed trip point of 0.15 A with a normally open output that closes when the sensed current rises above the setpoint, and it operates without an integrated power relay (no LED indicator on this model). The CSCGFN015NN supports a continuous sensing range up to 200 A and offers 600 V AC RMS isolation between the monitored circuit and the output, enabling safe, galvanically isolated control connections. It is specified for 50/60 Hz operation and has environmental limits of 5 to 140°F (−15 to 60°C) and 0 to 95% relative humidity (non‑condensing). Typical uses include alerting a controller to motor overload or abnormal operation, and, when paired with Setra’s snap‑on relay variants or other control hardware, it can be used to start/stop or trip equipment in response to current events. The device’s fixed, non‑adjustable trip point and noninvasive sensing make it well suited for applications demanding a simple, robust current threshold indication without additional power supply requirements.
