Siemens Circuit breaker, C20, 1+N-pole, 1MW, 230V, 6kA Part number 5SL6020-7

Product Overview

The Siemens 5SL6020-7 is a SENTRON series miniature circuit breaker designed for single-phase branch protection with neutral switching (1-pole + N). It features a C-curve tripping characteristic, a rated current of 20 A at 30 °C, and a rated breaking capacity of 6 kA (EN 60898), offering reliable protection against overloads and short-circuits in residential, commercial and infrastructure installations.

Key Features

• Miniature circuit breaker from the Siemens SENTRON 5SL60 series
• 1 + N-pole configuration (phase + neutral) for comprehensive circuit protection
• Rated current: 20 A at 30 °C; approximate 16.1 A at 60 °C
• C-curve tripping behaviour suitable for general loads with moderate inrush
• Rated breaking capacity (Icn) of 6 kA according to EN 60898
• Compact width of 18 mm (1 module) for efficient panel integration
• Screw-type terminals for conductor connection; suitable for solid and stranded conductors up to 16 mm²
• Sealable housing and halogen-free materials for enhanced safety
