The 193-EC3ZZ from Allen Bradley operates as a 3-phase overload relay within the E1 Plus series. It is designed for panel-mounted applications and supports substantial operational flexibility with a rated insulation voltage of 690 V AC. This device is capable of handling an impulse withstand voltage of 6 kV AC, making it robust against transient conditions.

Internally, the relay offers four discrete logic inputs and two discrete outputs, facilitating complex control and monitoring capabilities. The supplied control voltage spans from 11 V to 25 V DC, ensuring compatibility with a range of control systems. Additionally, the rated operating voltage is 690 V AC for standard conditions, as well as 600 V AC to accommodate various applications.

The environmental specifications highlight an operational temperature range from –20 °C to +55 °C and a storage temperature range that extends from –40 °C to +85 °C. This wide temperature tolerance allows the relay to function efficiently in diverse conditions. Humidity resilience is also significant, with operational capabilities in non-condensing environments between 5% and 95% relative humidity.

This unit holds an IP20 rating, indicating its suitability for indoor use where exposure to liquids and dust is minimal. Additionally, it operates effectively across a frequency range of 45 to 65 Hz, making it versatile for numerous applications in facilities requiring precise overload protection.
