Product details

Power Header for Board-to-Cable Duty

The 794878-1: The 4-wall shrouding with a locking ramp secures the mating receptacle against vibration and accidental pull-off.

12 A at 600 VAC — Where the Rating Matters

The 12 A current rating is specified at the connector level, meaning the per-contact temperature rise stays within the housing material limit at that current. The 600 VAC voltage rating is the maximum working voltage between adjacent circuits — sufficient for single-phase and many three-phase power distribution boards.

This header mates with Universal MATE-N-LOK receptacle housings that accept crimp terminals.
