What it is and its key ratings
The 5SY4416-6: The B-curve characteristic means it trips between 3 and 5 times rated current, suitable for resistive and small inductive loads like lighting or control transformers.
Mounting and integration
Occupies 4 modular width units (72 mm wide) on a DIN rail. Depth is 76 mm, height 90 mm. Mounting position is any – no derating for horizontal or vertical orientation. The quick assembly system and combined terminals top and bottom simplify busbar connection and reduce wiring time. IP20 with connected conductors – safe for enclosed panel installation.
Compliance and sourcing reality
Halogen-free and silicon-free. Overvoltage category III, pollution degree 3 – rated for fixed installation in building or industrial distribution boards.
