1SDA100176R1 ABB XT4N 160 Ekip Dip LSIG 40 A 3-Pole Circuit Breaker

Why Choose the ABB 1SDA100176R1 XT4N 160 Ekip Dip LSIG Circuit Breaker?

The ABB 1SDA100176R1 is a SACE Tmax XT4N moulded-case circuit breaker (MCCB) designed for reliable protection of low-voltage AC power distribution systems. This fixed, three-pole circuit breaker combines the compact XT4 platform with an Ekip Dip LSIG electronic trip unit rated at 40 A, providing comprehensive protection against overloads, short circuits and earth faults.

As part of the ABB SACE Tmax XT series, the XT4N is engineered for industrial and commercial distribution applications requiring compact dimensions, dependable switching and configurable electronic protection. The Ekip Dip LSIG release provides long-time overload, short-time selective short-circuit, instantaneous short-circuit and earth-fault protection, allowing effective coordination with other protective devices throughout an electrical installation.

The 1SDA100176R1 is supplied in a fixed, 3-pole configuration with front terminals. Its XT4N breaking part belongs to the N breaking-capacity class, while the 160 A frame size is paired with a 40 A Ekip Dip LSIG release, making the breaker suitable for protecting lower-current feeders and distribution circuits while retaining the capabilities of the XT4 platform.
