Allen-Bradley 1336-WA115

The Allen-Bradley 1336-WA115 dynamic brake chopper significantly enhances the braking torque capability of various 1336 series drives, including models B003 to C650. Designed with versatility in mind, this open-style assembly can boost braking torque from 10% to 100% when combined with braking resistors. It accommodates both single and multiple brake wiring configurations and operates seamlessly with a 230V AC drive voltage and a 375V DC turn-on voltage. The chopper peak transistor current rating reaches 400 A, with a minimum dynamic brake resistance of 1.25 Ω, ensuring robust performance. Enhanced safety features include internal replaceable fuses compatible with specific Ferraz Shawmut models, rated at 200A and 700V. With dimensions of approximately 11.44 x 12 x 9.44 inches and a weight of 25 lbs, the 1336-WA115 dissipates 190 watts under full-duty cycle conditions, making it a reliable choice for industrial applications requiring efficient braking solutions.
