Auxiliary Terminal Block
Additional terminal module for expanding power, control or signal connections of an electrical device.
An auxiliary terminal block is installed on or next to a compatible device to provide additional connection points.
It may be used for control circuits, auxiliary signals, potential distribution or expansion of the standard device terminals.
Key parameters include terminal count, permitted conductor sizes, current rating, clamp type and mounting compatibility.
Selection criteria include circuit function, voltage, current, conductor type, mounting position and compatibility with the specific equipment series.
Auxiliary terminal blocks for expanding the connection capability of electrical devices.
