Siemens Miniature circuit breaker, 1-pole, 230/400V, 6kA, 2A

Product Overview

The Siemens 5SY6102-6 is a 1-pole miniature circuit breaker (MCB) from the SENTRON / 5SY6 series. It offers overcurrent and short-circuit protection in low-voltage AC (230/400 V) distribution systems, making it suitable for residential, commercial, and industrial control panels and distribution boards.

Key Features

• 1-pole miniature circuit breaker, rated at 2 A nominal current
• Tripping characteristic: Class B — suitable for general lighting and small-load circuits
• Short-circuit breaking capacity: 6 kA (per EN 60898) in AC systems
• Rated for 230/400 V AC supply, compatible with standard single-phase and three-phase networks
• DIN-rail mounting with snap-on installation — compact and quick to install
• Touch-protected terminals and halogen-free design for safety and compliance with industrial standards
• Sealable and suitable for use as a main switch in control cabinets (per EN 60204-1 requirements)
