What this MCB covers
The Siemens SENTRON 5SY6006-7KL is a 1-pole-plus-neutral miniature circuit breaker rated 6 A with a C-curve trip characteristic and a 6 kA breaking capacity per EN 60898 at 230 V AC, 50/60 Hz. It occupies 1 modular width (18 mm) on standard DIN rail and switches the neutral conductor — so it isolates both line and neutral on a fault, which matters for single-phase final subcircuits where you want full disconnection.
That covers unheated utility rooms and outdoor-adjacent enclosures in most climates, but sustained condensation inside the enclosure would exceed the pollution-degree assumptions.
Depth is 76 mm, installation depth 70 mm, height 90 mm, width 18 mm (1 MW). Sealable with a lead seal for tamper-evident installations, e.g., metering or landlord distribution boards. Touch-protected terminals reduce arc-flash exposure during live metering.
