Siemens 5SL6116-6 SENTRON MCB — 16 A, B Curve, 1-Pole
Rated AC supply voltage is 400 V for multi-phase operation, 250 V single-phase, at 50/60 Hz. Maximum DC rating is 72 V.
Mounting position is unrestricted. The sealable design allows padlocking the toggle in the OFF position for lockout/tagout.
The 6 kA breaking capacity according to EN 60898 and IEC 60947-2 means this breaker safely interrupts a fault up to 6,000 A without welding its contacts or causing a flashover. For a 16 A final circuit in a domestic or light commercial board with a typical prospective fault level of 3–4 kA, that gives adequate headroom. Energy limitation class 3 means it lets through less energy than class 1 or 2 breakers, reducing stress on downstream wiring. The 10,000 mechanical operating cycles typical service life is standard for an MCB in this class.
