What is the difference between a screw terminal block and a pluggable system?

A screw terminal block (like AKZ250) is soldered directly onto the board – the wire is screwed in directly without a separate plug. This is cheaper and more space-saving, but not tool-free releasable. Pluggable systems (MSTB, IC) allow quick disconnection without a screwdriver.

What is 3-pole suitable for in LED applications?

For CCT outputs (2 channels + 1× common anode = 3 pins), 3-wire control signals, or mains terminals (L, N, PE) on LED controller boards.

Is the AKZ250 series available in other pole counts?

The AKZ250 series is available in 2–6 poles. Also available in the shop: AKZ350 2-pole (CN350-2-5.08), AKZ602 (3.81mm) and AKZ950.
