ABB 1SDA054015R1 SACE Tmax T4N 250 moulded case circuit breaker with PR222DS/P-LSI electronic trip unit, 100 A rated current and fixed four-pole front terminal configuration for low voltage power distribution.
The ABB 1SDA054015R1 is a high-performance Tmax T4N moulded case circuit breaker (MCCB) designed for dependable low voltage electrical protection in industrial and commercial distribution systems. As part of the trusted ABB SACE Tmax T series, this breaker provides robust protection for switchboards, distribution panels, motor control centres and OEM electrical assemblies.
This model is fitted with a PR222DS/P-LSI electronic trip unit, providing advanced long-time, short-time and instantaneous protection functions for AC installations. Its fixed four-pole construction and front terminal arrangement make it suitable for panel builders and electrical engineers requiring accurate, compact and flexible circuit protection.
With a 100 A rated current, T4N 250 frame size and four-pole fixed configuration, the ABB 1SDA054015R1 is ideal for feeder protection, sub-distribution circuits, machinery panels and power systems where four-pole switching or neutral isolation is required.
The ABB Tmax T4N range is engineered to provide reliable protection against overload and short circuit conditions while supporting continuity of service in low voltage power systems. Electronic trip units provide accurate protection settings, helping engineers improve selectivity and system reliability.
The ABB 1SDA054015R1 is particularly useful where a four-pole MCCB is required, providing protection and switching capability across three phases and neutral. This makes it suitable for distribution systems, control panels and electrical assemblies requiring full four-pole isolation.
