The Allen Bradley model 193-TAC24 bimetallic overload relay is engineered to provide essential protection in electrical circuits. Designed to operate effectively at input voltage levels up to 690 Volts AC, this overload relay handles current capacities between 16 to 24 Amperes, thus catering to a variety of load requirements.
In terms of design, the relay consists of one normally open (NO) and one normally closed (NC) contact, allowing for versatile control within electrical systems. It pairs effectively with contactors from the 100-C23 through 100-C37 series, ensuring compatibility across different setups. The trip mechanism is calibrated to trigger at 125% of the set dial, which provides ample warning before a fault condition arises.
This relay operates efficiently within a voltage range of 600 to 690 Volts AC and supports frequency ratings from 50 to 60 Hertz. Electrical insulation is rated at 500 Volts, contributing to the relay's reliability in various conditions. Furthermore, it is UL, CSA, and CE-certified, meeting stringent safety and performance standards.
For installation and maintenance, the relay features screw terminals for easy electrical connections, with an M4 screw size specification. A tightening torque of 1.8 Newton-meters is recommended for optimal connectivity. The 193-TAC24 also boasts a rated impulse strength of 6 kilovolts, allowing it to withstand voltage surges and ensuring durability in dynamic environments.
