The model CT1-X0-18-725-A11-MG specifies 1P operation and an 80 VDC rating, and the designation ends with 50K as shown in the model code. This device is suitable for applications where a reliable, fast-acting protective device is needed in DC distributions, such as battery-powered systems or DC power rails in control panels. The 25 A rating provides protection for moderate current loads without nuisance tripping under normal operating conditions, while the DC rating ensures compatibility with DC supplies and loads. The unit’s simple single-pole design supports easy integration into panel layouts and enables quick manual disconnection for service or testing.
