It provides no overload or short-circuit protection — it's a disconnect-only device for isolating a circuit under load. Front terminals accept busbar connection, and the IP40 front protection suits enclosed panel mounting.
The max power loss of 38 W at rated current matters for enclosure thermal calculations: a panel with several such switches needs ventilation or derating above 40 °C ambient.
The IP40 front (protected against tools >1 mm, no water protection) is standard for enclosed switchgear — not for washdown or outdoor use without an additional enclosure. The auxiliary contact pack includes one auxiliary switch (signal open/closed) and one trip alarm switch HP (signals a fault trip from the upstream protection), both rated for 24 V DC control circuits typical in PLC inputs.
