Product details

9 mm Pitch Header for 600 VAC Industrial Power

Its standout feature is the 0.354" (9.00 mm) pitch — wide enough to support a 600 VAC rating, which puts it in the power interconnect class rather than signal-only headers.

Through-Hole Termination with Tin Plating

Peer Comparison: 2-1903415-1 (Blue Housing)

The only difference between the 1-1903415-1 and the 2-1903415-1 is the insulation color — red vs blue. All other specs — 3 positions, 9 mm pitch, 600 VAC, board lock, locking ramp — are identical. Choose by color coding for your harness or panel identification.

Frequently asked questions

What is the mating connector for the 1-1903415-1 header?

The 1-1903415-1 mates with a Grace Inertia (GIC) series receptacle housing that accepts tab contacts. The locking ramp on the header engages with the latch on the mating housing. Confirm the circuit count and pitch (9 mm) match your receptacle.

What is the current rating of the 1-1903415-1?

The current rating is listed as 'Varies by Wire Gauge', meaning the ampacity depends on the wire size used in the mating receptacle. For a given wire gauge, refer to the Grace Inertia contact derating curve in the product drawing.
