The MGPBN250TB: This is a Merlin Gerin branded terminal strip — part of the panel accessories family. It's the physical block where you land incoming and outgoing wires, typically inside a distribution board or control panel. The 1.36 kg weight tells you it's a multi-way block, not a single-pole jumper. If you're replacing a damaged strip in an older Merlin Gerin panel, this is the direct drop-in. For new builds, it matches the Schneider Electric System pro M range footprint, but verify the mounting centers against your DIN rail or backplate.
What the weight tells you
At 1.36 kg, this terminal strip is a substantial block. Plan for mechanical support if mounting on a thin panel or door.
