1SDA060264R1 ABB T6L 630 PR222DS/P-LSI In=630 4p F F MCCB

Why Choose the ABB T6L 630 PR222DS/P-LSI In=630 4p F F?

The ABB 1SDA060264R1 is a genuine SACE Tmax T6L moulded case circuit breaker designed for demanding low-voltage power distribution systems. Identified as T6L 630 PR222DS/P-LSI In=630 4p F F, it combines a 630 A rated current, four-pole construction, fixed installation and front terminals with ABB's configurable PR222DS/P-LSI electronic protection.

The integrated PR222DS/P-LSI solid-state trip unit provides long-time overload, short-time short-circuit and instantaneous short-circuit protection. The overload setting is adjustable from 0.4–1 × In (252–630 A), the short-time protection range extends from 0.6–10 × In (378–6300 A), and the instantaneous protection is adjustable from 1.5–12 × In (945–7560 A).

The T6L performance level provides high fault-current interruption capability, including an ultimate short-circuit breaking capacity of 100 kA at 380/415 V AC. Its four-pole PR222DS/P-LSI release also provides selectable neutral protection at OFF, 50% or 100%, making this breaker a versatile solution for industrial switchboards and sophisticated four-wire distribution systems.

PR222DS/P-LSI Electronic Protection for Power Distribution

An LSI electronic trip unit provides three complementary protection functions. Long-time protection responds to sustained overloads, short-time protection allows coordinated response to high fault currents with intentional delay, and instantaneous protection provides rapid tripping for severe short circuits. On the ABB 1SDA060264R1, these functions provide significantly greater adjustment flexibility than a conventional fixed-protection arrangement.

The four-pole PR222DS/P-LSI release also supports selectable neutral protection at OFF, 50% or 100%, allowing the breaker to be configured according to the requirements of the four-wire distribution system. Combined with the T6L platform's 100 kA breaking capacity at 380/415 V AC, this makes the 1SDA060264R1 particularly suitable for demanding power-distribution installations requiring adjustable protection and selective coordination.

Typical Applications

• Industrial main distribution switchboards.
• High-current low-voltage power distribution systems.
• Commercial and infrastructure distribution boards.
• Transformer secondary circuit protection.
• Four-wire systems requiring configurable neutral protection.
• Industrial process and manufacturing power systems.
• Installations requiring selective short-circuit coordination.
• Systems with high prospective short-circuit currents.
