Siemens 5SL6616-6BB miniature circuit breaker, 400 V, 6 kA, 3+N-pole, B-curve, 16 A, Italy version.
The Siemens 5SL6616-6BB is a miniature circuit breaker (MCB) rated for 400 V with a 6 kA breaking capacity, configured as 3+N-pole, B-curve, 16 A, in the Italy version.
Snap-on mounting to DIN rail EN 60715. The 3+N-pole format occupies four modular-width positions in the distribution board. Wire termination accepts copper conductors up to 25 mm² for the line and load sides; torque settings per the terminal marking on the device.
The 5SL6616-6BB has a 6 kA breaking capacity at 400 V, which is the standard rating for domestic and light commercial MCBs per EN 60898.
The B-curve trips between 3 and 5 times rated current (48–80 A for this 16 A unit), making it suitable for resistive or lighting loads with low inrush current.
The 5SL6616-6BB is sourced and quoted to order against an RFQ through independent distribution; availability and current pricing are confirmed at quote time.
