What it is and what the ratings mean
The Siemens 5SV1616-6KK10 is a SENTRON RCBO (residual current circuit breaker with overcurrent protection) in a 1P+N configuration — one protected pole plus a switched neutral. It carries a 10 A thermal rating at 30 °C ambient, derated to 7.4 A at 70 °C (the full curve from 30 °C through 70 °C is specified). The B tripping characteristic means the magnetic release operates at 3 to 5 times the rated current, so it clears short-circuit faults fast enough to protect solid-state loads and small motor starters without nuisance trips on moderate inrush. Breaking capacity is rated at 6 kA according to EN 60898 (the standard for household and similar installations) and 25 kA according to IEC 60947-2 (the industrial standard for low-voltage switchgear). The dual rating means it qualifies for both domestic distribution boards and industrial control panels, provided the prospective fault current at the installation point does not exceed the lower 6 kA figure under the consumer-standard test conditions.
Panel fit and integration
The housing is 18 mm wide (1 modular width), 77 mm deep, and 90 mm tall, with a 70 mm installation depth behind the panel. Mounting position is any orientation. Supply can enter from top or bottom, which simplifies busbar routing in crowded enclosures. Rated IP20 with conductors connected and the distribution board installed — standard for enclosed panel use, not for wet-area standalone mounting. Halogen-free and silicon-free construction matters for panels in critical infrastructure or environments where off-gassing during a fault could damage nearby electronics or create corrosive byproducts. Pollution degree 2 and overvoltage category III cover fixed-installation environments like distribution boards in commercial buildings and industrial control cabinets.
Lifecycle and sourcing
The 5SV1616-6KK10 carries a lifecycle status of current production. It is sourced and quoted to order against an RFQ through independent distribution.
