The ABB 1SDA063437R1 is a T5V 400 molded case circuit breaker fitted with a TMA 320-3200 A electronic trip unit and fixed front terminals, rated for 1150 VAC. The TMA trip unit provides adjustable thermal-magnetic protection with a wide current range — 320 to 3200 A — so the same breaker frame can be set for different load sizes during commissioning. The 1150 VAC rating means it handles higher-voltage industrial distribution, not just the standard 480/600 V class.
