Product Description:

The RZW02.1-015-040 Braking Resistor is one of the most useful devices used in motion control tasks to absorb excess energy produced during motor deceleration. It is designed by Bosch Rexroth Indramat a reputable company which provides high quality products for industrial automation.

The RZW02.1-015-040 brake resistor is capable to dissipate 15 kW of power and it has 18 Ohm of resistance value. The 18 Ohm resistance supports controlled braking force in the system. The model comes with the lowest connectable resistance value of 17.5 Ohm. The cross-section of conductor at 40% duty is 10 mm². The thermal time constant of the resistor is 100 seconds which allows balanced load absorption during operation. The peak power capacity under 40% duty cycle is 13.5 kW. The housing material is made of galvanized steel for longevity. The protection category of the resistor is IP 20. The thermal time constant enables stable energy absorption over time. The 13.5 kW peak power allows high braking load for short duration. The 10 mm² cable size supports safe current transfer during cycles. The IP 20 rating ensures protection in indoor industrial environments. The galvanized steel housing improves heat resistance and mechanical protection. Thid resistor performs in repetitive braking operations and its resistance range prevents excess current flow in the system.
