1SDA100312R1 ABB Ekip Dip LSI 250 A XT4 4-Pole Trip Unit

Why Choose the ABB 1SDA100312R1 Ekip Dip LSI Trip Unit?

The ABB 1SDA100312R1 is an Ekip Dip LSI electronic trip unit designed for compatible ABB Tmax XT4 4-pole moulded case circuit breakers. Rated at 250 A, it provides electronic overload and short-circuit protection for AC low-voltage electrical distribution systems.

The Ekip Dip platform provides configurable solid-state protection using straightforward settings for effective circuit coordination. Its LSI protection functions combine long-time, short-time and instantaneous protection, helping protect cables, feeders and connected electrical equipment against sustained overloads and different levels of short-circuit current.

Designed as a separate 4-pole electronic protection release, the 1SDA100312R1 is intended for use with the ABB Tmax XT4 platform. Its 250 A rated current makes it suitable for higher-current distribution circuits requiring configurable electronic protection within industrial, commercial and OEM electrical installations.
