OTDC Special solutions
Multi-circuit solutions – for multiplied benefits
With OTDC switches it is possible to control two or three circuits simultaneously with only one switch.
Load-side combining – High performance, compact solution
Increase the current output up to three times in a 37% lower space. The load-side combining solutions allow the use of OTDC switches in applications that require up to 800 A (UL) or 1500 A (IEC) outputs.
IEC, 2 x 315/400/500 A IEC, 3 x 315/400/500 A
UL, 2 x 250/320/400 A UL (grounded), 2 x 250/320/400 A
Higher voltage – 1500 V DC solutions
ABB is ready to respond to the demands of the global market: OTDC is now available for 1500 V DC from 315 to 500 A (IEC) and from 250 to 400 A (UL).
