AFC16-04-00-81 ABB 30A 4-Pole Contactor, 4 Normally Closed Poles, 24V AC Coil, DIN Rail Mount

If you are pulling a 4 pole contactor that has to sit closed until the coil pulls it open, this is the one. The ABB AFC16-04-00-81 gives you four normally closed main poles good for 30 A general use at 600 V UL, or 30 A AC-1 at up to 690 V on the IEC side. It clips onto 35 mm DIN rail and lands on screw terminals, so you are not chasing special tooling on the panel.

Coil code 81 means you are feeding it 24 V AC, and it works on 50 Hz or 60 Hz. This is an AF platform unit, so it shares the same footprint and accessory range as the rest of your AF gear. ABB order code is 1SBL171101R8100 if you need to match it to a bill of material.

Common Applications

• Panel work where the load needs to stay on until the coil is energized
• General use and resistive load switching up to the 30 A rating
• 24 V AC control schemes running off a transformer or automation controller
• Adding a normally closed contactor to an existing AF platform lineup
• Machine and equipment panels built to IEC or UL requirements

Key Features

• Four N.C. poles: Poles sit closed at rest and open when you energize the coil.
• 30 A rating: Handles 30 A UL general use and 30 A AC-1 under IEC.
• 24V AC coil: Coil code 81 runs on 24 V AC at 50 Hz or 60 Hz.
• Screw terminals: Standard screw connections on the poles and the coil.
• DIN rail mount: Snaps onto 35 mm rail for a fast panel install.
• AF platform fit: Same accessory range and add-on aux blocks as the rest of the AF line.

FAQ

Is this contactor normally open or normally closed?
Normally closed. All four main poles are closed until the coil is energized, then they open.

What coil voltage do I need to feed it?
24 V AC. The 81 coil code covers 24 V AC at 50 Hz and 24 V AC at 60 Hz.

How much current will it carry?
30 A UL general use at 600 V, and 30 A AC-1 at up to 690 V under IEC.

Will my AF accessories fit it?
Yes. It is built on the AF platform and takes add-on auxiliary contact blocks from the same accessory range.

How does it mount?
It mounts on 35 mm DIN rail and uses screw terminals on the main poles and coil.
