Product details

SIRIUS 3RT2026-1NF30 — Size S0 Power Contactor, 95-130 V Coil

The coil is rated for 95-130 V AC, with an inrush current peak of 15 A at pickup.

Envelope and Mounting

These clearances matter for heat dissipation and arc flash containment in a crowded panel — the 10 mm forward clearance is the one most often overlooked when gland plates or busbars are close.

Maximum switching frequency varies by duty class: 1,000 operations per hour at AC-1 (resistive), 750/h at AC-2 and AC-3 (motor starting/running), and 250/h at AC-4 (plugging/inching). The AC-3e rating also caps at 750/h. These limits are thermal — exceeding them will overheat the contact tips, especially under AC-4 duty where the arc is struck at full load each time.

Frequently asked questions

Where can I buy 3RT2026-1NF30 and how do I get a price?

The 3RT2026-1NF30 is sourced and quoted to order against an RFQ. Submit a request for quote (RFQ) through this listing; availability and current pricing are confirmed at quote time.

What is 3RT2026-1NF30's listed depth?

The depth is 107 mm. Combined with the 45 mm width and 85 mm height, the envelope fits standard Size S0 panel cutouts.

What wire sizes does the 3RT2026-1NF30 accept?

Solid conductors from 1 to 10 mm² and stranded conductors from 1 to 10 mm². The auxiliary contact terminals accept 2x (0.5-1.5 mm²) or 2x (0.75-2.5 mm²) solid or stranded.

Will 3RT2026-1NF30 drop into a panel specified around 3RT2026-1BB40-0UA0 without rewiring?

Both are Size S0 contactors with the same 45 mm width and screw-type terminals, so the mechanical footprint and terminal layout are identical. The coil voltage differs — the 1NF30 uses 95-130 V AC, while the 1BB40 variant uses a different coil. Verify the control voltage matches before swapping; if it does, no rewiring is needed.
