Siemens Miniature circuit breaker, class C, 2-pole, 400V, 6kA, 10A Part number 5SL6210-7

Product Overview

The Siemens 5SL6210-7 is a miniature circuit breaker from the Sentron 5SL6 series, designed for dual-pole protection in commercial and industrial applications. With a rated current of 10 A, a C-curve tripping characteristic, and a rated breaking capacity of 6 kA at 400 V AC, it delivers reliable circuit protection while optimising panel footprint.

Key Features

• 2-pole (2P) miniature circuit breaker for phase-and-phase or phase-and-neutral circuits
• Rated current: 10 A
• Tripping characteristic: C-curve — suitable for moderate inrush loads
• Breaking capacity: 6 kA at 400 V AC (C/U) according to standard testing
• Compact width: 36 mm (2 modular width units) for efficient switchboard layout
• Halogen-free, silicon-free materials; sealable design for added safety and compliance
