DRIVES AND FREQUENCY CONVERTERS
ERB braking resistors 15 W–34 kW
Country: Germany · Model: ERBU / ERBM / ERBP / ERBG / ERBS
ERB series braking resistors, 15 W–34 kW, dissipate the drive's braking energy as heat. They are used with frequency inverters and servo inverters when the drive runs for a long time in generator mode or brakes large moments of inertia. The series has five types, ERBU, ERBM, ERBP, ERBG and ERBS, with protection from IP20 to IP66.

Description
The resistor switches on when the DC bus voltage exceeds the response threshold, and the drive does not trip on overvoltage or stop by coasting. The ERBU in a metal cartridge is mounted directly on the drive by cable, at 35 W (IP20), 20 W (IP65) and 15 W (IP66), without a thermal contact. The ERBM in an aluminium profile has 20–150 W (IP20), 86–135 W (IP23) and 50–120 W (IP54), and the ERBP for an IP23 cabinet is 200–300 W. The ERBG with a steel grid and bolted terminals IP23 gives 1.9–34 kW, and the ERBS with a terminal box for wall mounting IP66 gives 150–6300 W. The ERBM, ERBP, ERBG and ERBS have a thermal contact for overheating monitoring. Horizontal installation is permitted with a current derating of 30 % for the ERBP and 20 % for the ERBS, and the ERBG is installed vertically up to 10 kW. Operating conditions are −10 to +55 °C with derating of 2.5 %/°C above +45 °C (ERBG above +40 °C), storage −25 to +60 °C, transport −25 to +70 °C, altitude up to 4000 m (above 1000 m a derating of 5 % per 1000 m), vibration resistance up to 0.7 g. Marks CE (2014/35/EU), UKCA, UL508/CSA and RoHS 2011/65/EU.
How to choose
The type is chosen by power and mounting place. For small power up to 35 W on the drive itself take the ERBU, for a cabinet the ERBM or ERBP, for 1.9–34 kW the ERBG, and for wall mounting and IP66 the ERBS. An alternative to a resistor is the r750 regeneration module or the built-in regeneration module of the i550/i650 motec inverters.

FAQ
What power ratings do the ERB braking resistors have?
From 15 W to 34 kW. ERBU 15–35 W, ERBM 20–150 W, ERBP 200–300 W, ERBS 150–6300 W, ERBG 1.9–34 kW.
What protection rating does the ERB series have?
From IP20 to IP66 depending on the type. For example, the ERBS has IP66 and the ERBG IP23.
Which ERB resistors have a thermal contact?
The ERBM, ERBP, ERBG and ERBS. The ERBU has no thermal contact and is spark-safe.
When does the drive switch on the braking resistor?
When the DC bus voltage exceeds the response threshold. Then the drive does not trip on overvoltage.
What can replace a braking resistor?
The r750 regeneration module or the built-in regeneration module of the i550/i650 motec inverters.
