Siemens Mini circuit breaker, C-curve, 1-pole, 230/400V, 6kA, 2A Part number 5SL6102-7

Product Overview

The Siemens 5SL6102-7 is a 1-pole miniature circuit breaker (MCB) from the SENTRON 5SL6 series. It is designed for over-current and short-circuit protection in low-voltage AC distribution systems, suitable for residential, commercial, or light-industrial installations. With a nominal current rating of 2 A and a “C”-characteristic trip curve, it offers reliable protection for small branch circuits or sensitive loads. The compact DIN-rail design and standard width make it suitable for consumer units, sub-boards, or modular distribution boards.

Key Features

• 1-pole miniature circuit breaker (MCB), SENTRON 5SL6 series
