1SDA100021R1

The ABB 1SDA100021R1 is a Tmax XT2N 160 molded-case circuit breaker (MCCB) designed for reliable protection and switching in low-voltage electrical distribution systems. It is configured as a 4-pole, fixed-mount circuit breaker with front terminals and incorporates an Ekip Dip LSIG electronic trip unit rated at 25 A. ABB's catalog identifies the exact product as XT2N 160 Ekip Dip LSIG In=25A 4P F F. The Ekip Dip LSIG electronic release provides four main protection functions: L (Long-time) for overload protection, S (Short-time) for short-circuit protection, I (Instantaneous) for rapid short-circuit protection, and G (Ground-fault) protection. This makes the breaker suitable for protecting electrical feeders, distribution circuits and equipment where four-pole protection is required.
