ABB 1SDA054433R1 SACE Tmax T5V630 fixed four-pole 630 A moulded case circuit breaker with PR221DS-I electronic instantaneous protection, selectable neutral protection and 200 kA ultimate breaking capacity at 380–415 V AC.
£5,993.31
The ABB 1SDA054433R1 is a high-performance SACE Tmax T5V 630 moulded case circuit breaker (MCCB) designed for short-circuit protection and isolation in demanding low-voltage electrical systems. Configured as a fixed four-pole breaker with front terminals, it combines a 630 A rated current with ABB's PR221DS-I electronic trip unit.
Unlike LS/I or LSI releases, the PR221DS-I version is configured specifically with adjustable instantaneous magnetic protection. Its magnetic threshold can be set from 1–10 × In, corresponding to 630–6,300 A with this 630 A release. The four-pole version also provides selectable neutral protection settings of OFF, 50% or 100%.
The T5V performance level is designed for installations with exceptionally high prospective fault currents. The 1SDA054433R1 provides an ultimate short-circuit breaking capacity of 200 kA at 380–415 V AC, with high interruption performance maintained across a wide operating-voltage range. This makes it a strong choice for industrial and commercial systems requiring instantaneous short-circuit protection at high fault levels.
The ABB SACE Tmax T5V platform is engineered for demanding low-voltage systems where substantial current capacity and exceptionally high short-circuit interruption performance are required. With a 630 A rated current and 200 kA Icu at 380–415 V AC, the 1SDA054433R1 provides robust interruption capability for installations with significant prospective fault currents.
Its PR221DS-I electronic trip unit provides adjustable instantaneous magnetic protection from 1–10 × In, while the four-pole configuration offers selectable neutral protection. Fixed mounting and front terminals provide a practical arrangement for integration into industrial switchboards, distribution panels and other low-voltage electrical assemblies.
