Siemens 5SV1316-1GV16 — RCBO, 1P+N, 16 A, 30 mA, Type AC, Curve C
The neutral pole is switched and protected — the 1P+N configuration means the neutral is opened and closed with the line, not just a solid link. That matters when you need isolation on both conductors for maintenance or fault clearing.
At 18 mm wide (1 modular unit), 90 mm tall, and 77 mm deep, this RCBO snaps onto a standard 35 mm DIN rail. The installation depth is 70 mm — the extra 7 mm is the front projection of the toggle and test button. If the enclosure itself is not IP-rated, this device alone does not provide washdown or outdoor protection.
The 30 mA residual-current sensitivity (type AC) catches sinusoidal AC earth faults — the common kind from a live conductor touching grounded metal or a person making contact with line and ground. The curve C overcurrent characteristic means the magnetic trip fires at 5 to 10 times rated current (80 to 160 A for this 16 A unit), suitable for loads with moderate inrush like small motors, lighting ballasts, or capacitor banks. For purely resistive loads or long cable runs with no inrush, curve B would be a better selectivity match. Halogen-free and silicon-free construction means the plastic materials do not emit corrosive halogen gases when burned — relevant for installations in confined spaces, public buildings, or areas with sensitive electronic equipment where a fire could cause secondary damage from acidic smoke.
