Product details

Current and Voltage Ceiling for Control Circuits

The 1546018-3: Rated 12 A at 300 V (UL) — this is the continuous current per circuit at the rated voltage.

Side Interlock for Multi-Pole Ganging

The interlocking (Side) feature lets you snap multiple 3-position plugs together side-by-side to form a larger multi-pole connector block — no separate hardware needed. This is useful when a terminal block header has more than 3 positions and you want to populate it with individual plug modules rather than a single wide plug.
