Why Choose the ABB 1SDA054531R1 T5V 400 MCCB?

The ABB 1SDA054531R1 is a fixed four-pole moulded case circuit breaker (MCCB) from the ABB SACE Tmax T series, designed for high-voltage AC and DC power distribution and circuit protection applications. This T5V 400 circuit breaker features an adjustable TMA thermal-magnetic trip unit, front terminals for copper cables and a fully rated neutral, providing reliable protection for demanding industrial electrical installations.

Designed for specialised high-voltage applications, the breaker has a rated operational voltage of up to 1,150 V AC and 1,000 V DC. Its four-pole configuration provides a neutral rated equally to the phases, while the fixed construction enables straightforward installation in suitable switchboards and electrical distribution assemblies.

With a rated current of 320 A and an adjustable magnetic trip range of 1,600–3,200 A, the 1SDA054531R1 is suited to transformer, generator, installation protection and industrial power distribution applications where dependable circuit interruption and switching are required.
