The Siemens SENTRON 5SJ6506-6 is a 1P+N miniature circuit breaker rated 6 A with a B tripping characteristic, designed for 240 V AC circuits. Its 6 kA breaking capacity is certified to both EN 60898 and IEC 60947-2, covering residential and light industrial panel applications. The B-curve trips between 3 and 5 times rated current, making it a standard choice for general-purpose lighting and socket-outlet protection where inrush currents are low.
Panel fit and mounting
Occupies 2 width units on a DIN rail; the 70 mm installation depth leaves clearance behind the gland plate for most standard enclosures. Mounting position is unrestricted — the breaker can be installed horizontally or vertically without derating, which simplifies layout in crowded sub-distribution boards.
Lifecycle and sourcing
Current lifecycle stage from Siemens. Sourced and quoted to order against an RFQ through independent distribution.
Environmental and compliance notes
Halogen-free and silicon-free construction, with a storage temperature range of -40 °C to +75 °C. Rated for overvoltage category III and touch protection is provided on the terminals. IP20 with connected conductors — suitable for enclosed distribution boards, not for wet or washdown environments.
