300 W aluminium braking resistor

This 100 Ohm wirewound resistor is built for industrial power supply, transducer and elevator circuits that need reliable energy dissipation. The aluminium housing provides effective heat radiation and suits mounting on a cooling plate in harsh environments. It is not for buyers who need a lower power rating or a different resistance value.

300 W continuous power limit

The resistor is rated for 300 W of continuous braking power with a ± 5 % tolerance on the 100 Ohm value. Exceeding this power level will overheat the element and degrade performance. It is not for applications that demand higher sustained dissipation or tighter tolerance without additional thermal management.

100 Ohm capacity and headroom

At 100 Ohm and 300 W the unit comfortably handles typical regenerative braking currents in motor drives and elevator systems. The 614 g aluminium body and 11.8 inch cable give adequate thermal mass and wiring reach for standard installations. It runs out of headroom when peak power exceeds the rated 300 W or when ambient temperature prevents sufficient cooling.

Questions about this item

What resistance value does this braking resistor provide?

The resistor is rated at 100 Ohm with a tolerance of ±5%, giving a consistent load for regenerative braking circuits.

How much continuous power can the 300 W rating actually dissipate in a machine?

The aluminium housing radiates heat effectively, allowing the unit to absorb up to 300 W continuously when mounted on a cooling plate with good thermal contact.

What connection method does the resistor use and what current can the terminals handle?

It comes with 11.8-inch nylon-wrapped leads ending in solder-lug terminals sized 0.291" OD by 0.157" inner diameter, suited for the current levels typical of a 300 W, 100 Ohm load.
