Square D LC2D09BD – Frequently Asked Questions

1) Does the Square D TeSys Deca LC2D reversing contactor come with a mechanical interlock, or do I have to add one?
The interlock is built in. The LC2D is supplied as a complete reversing assembly, two contactors mechanically interlocked so forward and reverse can never be energized at the same time. You don't order a separate interlock kit or wire one up. It's a 3-pole, 3 NO configuration with 2NO+2NC auxiliary contacts already fitted for your control and signalling circuits.
2) Which LC2D size do I pick for my motor?
Size by motor full load amps. Three options are offered: 9A, 12A, and 25A. Pick the one at or above your motor's nameplate FLA. At the top of the range, the 25A version handles 25A AC-3 at up to 440V AC, which is 11kW at 400V. Ordering part numbers are LC2D09BD, LC2D12BD, and LC2D25BD.
3) Can I use this Square D reversing contactor on a 600V panel?
Yes. The power circuit is rated to 690V AC (25 to 400 Hz) per IEC, with a rated insulation voltage of 690V under IEC 60947-4-1 and 600V under UL/CSA. So a 600V system is inside the UL/CSA rating. It will also switch up to 300V DC. Note the AC-3 current rating of 25A applies at 440V AC and below.
4) Is this contactor UL Listed for a control panel going through inspection?
It is UL Listed and CSA Certified, and it conforms to IEC 60947-4-1, IEC 60947-5-1, and IEC 60335-1. It also carries CB, GOST, UKCA and CCC marks, plus BV, RINA, DNV, GL and LROS marine certifications if the panel is going shipboard.
5) My control circuit is 120V AC. Does the Square D LC2D work, or do I need a different contactor?
The Square D TeSys Deca LC2D ships with a 24V DC control coil, so a 120V AC control circuit would need a 24V DC control transformer and power supply ahead of it. The ABB AF16 in the AF Series carries a 100-250V AC/DC control coil, which accepts 120V AC control directly without a separate supply. Match the coil to the control voltage you already have in the panel before choosing between them.
6) Is the ABB AF16 contactor a direct substitute for the Square D LC2D reversing contactor?
No, they solve different problems. The Square D TeSys Deca LC2D is a 3-pole reversing contactor, meaning two power contactors joined with a mechanical interlock so forward and reverse cannot close at the same time. The ABB AF16 in the AF Series is a single 3-pole contactor with a 1NO auxiliary contact, so it switches a motor in one direction only. To reverse a motor with AF16 devices you would need two of them plus a separate interlock kit and reversing wiring. If the panel drawing calls for a reversing starter as a single assembly, the LC2D 3-pole reversing configuration is the match.
7) Does the LC2D mount on DIN rail or does it need a panel plate?
Either. Plate mounting and rail mounting are both supported, so it drops onto DIN rail in a standard control enclosure or screws straight to a back panel. Front face protection is IP20 per IEC 60529, which means it needs to sit inside an enclosure rather than being exposed.
8) Will this contactor hold up in an unheated outbuilding or a hot machine room?
Ambient operating range is -40C to 60C, with derating up to 70C. The 25A AC-3 rating is stated at under 60C, so above that you size down. Mechanical durability is 30 million cycles, which covers high-cycle reversing duty like conveyors and hoists.
9) What is the difference between this reversing contactor and a single ABB AF16 contactor?
They solve different problems. The LC2D is a factory-assembled reversing pair with the mechanical interlock and 2NO+2NC auxiliaries included, for forward/reverse motor control. The ABB AF16 from the AF Series is a single 3-pole contactor with one NO auxiliary contact and 100-250V AC/DC control, so it is a non-reversing device and its wide-range coil accepts common 120V or 240V control power directly. If you only need to start and stop a motor in one direction, a single contactor is the simpler buy; if you need to reverse rotation, you need the interlocked pair.
10) Does the LC2D include overload protection for the motor?
No. What you get is the switching and the interlock: 3 NO power poles, 2NO+2NC auxiliary contacts, and the 24V DC coil. Motor overload protection is a separate device you add ahead of or below the contactor, plus upstream short circuit protection. Plan the panel with a thermal overload relay and branch protection sized to the motor.
11) I only need to start a motor in one direction. What should I use instead of a reversing contactor?
A single non-reversing 3-pole contactor is the simpler choice. The ABB AF16 in the AF Series is a 3-pole contactor with one normally open auxiliary contact, which covers a straightforward across-the-line motor start where direction never changes. The Square D TeSys Deca LC2D adds the second power block and the mechanical interlock that only matter when the load has to run forward and reverse, along with 2NO+2NC auxiliary contacts for the added control and signalling that a reversing circuit typically needs.
12) What is the difference in motor sizing between the Square D LC2D and the ABB AF16?
The Square D TeSys Deca LC2D reversing contactor is offered by motor full load amps at 9A, 12A, and 25A, with the frame rated 25A AC-3 at up to 440V AC and a power circuit rated to 690V. That gives you three sizing points off one design so you can match the contactor to the motor nameplate. The ABB AF16 is a separate AF Series device and is sized on its own AF frame, so you would size it against ABB's own AF selection rather than assuming a one-for-one swap with an LC2D of the same nominal amps.
13) How many spare auxiliary contacts do I get for run indication and interlocking?
Four, in a 2NO+2NC arrangement, available for supplemental control and signalling. That is enough for a run pilot light plus a seal-in or a PLC input on each direction without stacking an add-on auxiliary block. Power pole terminals take M4 hardware.
