The Allen Bradley 190S-CND2-DC20C is a thermal-magnetic trip block used for effective circuit protection. Capable of operating across a frequency range of 50 to 60 Hz, this trip block is designed to handle various current levels efficiently. Its adjustable thermal range spans from 4 to 6 A, allowing customization for specific applications. Furthermore, the magnetic range of this device is adjustable between 50 and 80 A, providing adequate flexibility.

It is rated for continuous current of 42 A and has a short-circuit capacity ranging from 3 to 4.5 kA at a maximum voltage of 690 V. The making and breaking capability of approximately 400 A AC enhances its reliability in circuit interruptions. With typical power loss values of 14 to 23 watts, it maintains efficiency during operation.

Thermal accuracy is specified at ±5 % at 40°C and ±10 % at 60°C, ensuring precision in performance under varying temperatures. The device also features a short-trip multiplier ranging from 8.5 to 14 times the thermal setpoint, adding an additional layer of safety. It further guarantees magnetic tolerance of ±20 %, confirming its robustness in demanding conditions. The unit's protection rating is classified as IP20, signifying its resistance to dust ingress but limited to vertical environments. Additionally, the terminal capacity allows for single wires ranging from 1 to 16 mm², optimizing connectivity options. Its design supports mounting in any position within a ±30° angle, enhancing installation flexibility.
