BTA20.2-NB-HP-VB-BS

Product Description:

The BTA20.2-NB-HP-VB-BS is a power busbar trunking system from the BTA20 series by Bosch Rexroth Indramat, built to handle higher current demands in heavy-duty setups. Rated for 2000 A, it supports solid energy distribution without the voltage dips or heat accumulation seen in lighter builds. The system comes pre-configured with 3 phase + neutral + PE conductors, designed to keep distribution safe and balanced even when loads shift unexpectedly.

Insulation is handled through epoxy resin, which helps both with electrical stability and long-term endurance under thermal stress. 690 V rated voltage and 50/60 Hz frequency make it compatible across standard industrial grids. The trunking follows IEC 61439-6 standards, and its short circuit withstand rating sits at 50 kA (1s), with a 110 kA peak capacity—both crucial for managing fault conditions without immediate failure. Protection level is IP55, so it holds up in environments where splashes, dust, or partial exposure are normal operating conditions.

Each segment is 3 meters in length and can be mounted either horizontally or vertically depending on the plant layout. The system works within an operating temperature range of -25°C to +40°C, so it's ready for colder storage areas as well as warmer production spaces. Copper conductors inside the casing keep resistance low and power loss minimal, making the unit suitable for continuous loads with little downtime. Fire resistance is IEC 60331 compliant, so in the event of a fire, the system can keep transmitting power long enough for safety protocols to trigger. The BTA20.2-NB-HP-VB-BS offers a compact, standardized way to manage high-current supply while keeping mechanical stress and maintenance requirements low.
