GACIA SB6L B 1P 6A Miniature Circuit Breaker, 6 kA, B Curve, 1-Pole, 6 A

With a short-circuit breaking capacity of 6 kA and a B tripping curve, this GACIA SB6L B 1P 6A miniature circuit breaker delivers precise overcurrent and short-circuit protection for residential and commercial installations. Rated at 6 A and 230 V AC, it ensures reliable performance on 50/60 Hz networks.

Overview

The GACIA SB6L B 1P 6A is a single-pole miniature circuit breaker (MCB) engineered to protect electrical circuits from overloads and short circuits. Its B curve characteristic means it trips instantly at 3 to 5 times the rated current, making it ideal for resistive loads such as lighting and socket circuits. The device complies with IEC/EN 60898-1, guaranteeing safety and interoperability in standard DIN rail installations.
