What it is and where it sits in the series
At 30 A per position at 125 VAC, the 1301470073 carries the highest current rating in the series — the 3-position, 30 A headline directly governs wire gauge selection and branch-circuit protection sizing for the harness builder.
Compliance and sourcing
CSA and UL listings cover North American build acceptance — for equipment destined in Canada or the US, both agency marks on the same part number removes the need to qualify a second source solely for compliance. The 125 VAC rating is the nameplate limit; do not apply this connector at higher voltage even if the mechanical interface would physically fit a different NEMA configuration.
