Schneider Electric LC1D09M7 TeSys D 9 A Contactor 220 V AC

LC1D09M7 contactor: 9 A TeSys D contactor with a 220 V AC coil

The LC1D09M7 is a Schneider Electric TeSys D contactor with three normally open power poles, rated 9 A in AC-3 up to 440 V, with a 220 V AC 50/60 Hz coil. It is one of the smallest frames of the LC1D series and the datasheet range line reads TeSys Deca Advanced. The LC1D09M7 also has a built-in auxiliary set of 1 NO + 1 NC. Seven Star LLC supplies the LC1D09M7 in Oman and the GCC as an independent supplier based in Muscat.

Decoding the reference: LC1D is the TeSys D contactor, 09 is the 9 A frame, and M7 is the 220 V AC 50/60 Hz coil code that the title states. The datasheet title mentions AC-3, a voltage of up to 440 V and 9 A, so the three figures together describe a small motor starter contactor.

Technical specifications of the LC1D09M7

Motor ratings of the LC1D09M7 by voltage

The datasheet gives AC-3 motor power as 2.2 kW at 220/230 V, 4 kW at 380/400 V, 4 kW at 415/440 V, 5.5 kW at 500 V and 5.5 kW at 660/690 V, all at 50/60 Hz. The same values are listed under AC-3e. In horsepower, the datasheet lists 1 hp at 230/240 V single phase, 2 hp at 200/208 V and 230/240 V three phase, 5 hp at 460/480 V and 7.5 hp at 575/600 V.

Resistive duty is listed under AC-1 at 25 A up to 440 V, which is where the large gap between 9 A and 25 A comes from: motor starting currents are many times the running current, while resistive loads have none.

Coil, timing and durability data for the LC1D09M7

The coil of the LC1D09M7 is 220 V AC at 50/60 Hz, with an inrush of 70 VA at 50 Hz and cos phi 0.75, and a hold-in of 7 VA at 50 Hz and cos phi 0.3. Operating limits are 0.8 to 1.1 Uc at 50 Hz and 0.85 to 1.1 Uc at 60 Hz up to 60 °C, with drop-out between 0.3 and 0.6 Uc. The datasheet states that the coil has no built-in suppressor module. Operating time is 12 to 22 ms closing and 4 to 19 ms opening.

Mechanical durability of the LC1D09M7 is 15 Mcycles. Electrical durability is 2 Mcycles at 9 A AC-3 and 0.6 Mcycles at 25 A AC-1, both at up to 440 V. The maximum rate is 3600 cycles per hour at 60 °C.

Built-in auxiliary contacts and safety data of the LC1D09M7

The contactor includes a 1 NO + 1 NC auxiliary contact set, described as mechanically linked per IEC 60947-5-1, with the NC contact being a mirror contact per IEC 60947-4-1. The non-overlap time between NC and NO is 1.5 ms. The signalling circuit is protected by a 10 A gG fuse and has a 5 mA, 17 V minimum switching level.

For safety applications the datasheet gives B10d values for the LC1D09M7: 1369863 cycles at nominal load and 20000000 cycles with mechanical load, under EN/ISO 13849-1. These help a machine builder calculate the performance level of a safety function that uses the contactor.

Fitting the LC1D09M7 in a starter: protection and coordination

The datasheet lists associated fuses of 25 A gG for type 1 coordination and 20 A gG for type 2 coordination at up to 690 V. A motor starter is normally built from this contactor, a thermal overload relay or a motor circuit-breaker, and a short-circuit device. The correct combination depends on the motor and is chosen from the coordination tables.

Before ordering the LC1D09M7, run through these points: motor up to 4 kW at 400 V in AC-3; coil 220 V AC 50/60 Hz matching the panel; the built-in 1 NO + 1 NC, with extra blocks such as the LADN22 on the front; an overload relay or motor breaker added; 45 mm of rail width; and the real duty checked against the LC1D09M7 ratings.

The LC1D09M7 mounts on a rail or a plate and measures 77 mm high, 45 mm wide and 86 mm deep with a net weight of 0.32 kg. Power and control terminals are screw clamp types for 1 to 4 mm² flexible wire, tightened at 1.7 N.m.

Environment, approvals and mounting limits of the LC1D09M7

The permissible ambient temperature around the device is -40 to 60 °C, with operation at 60 to 70 °C possible with derating, and altitude is 0 to 3000 m. The datasheet lists IP20 on the front face, protective treatment TH, climatic withstand per IACS E10 and damp heat, fire resistance of 850 °C and flame retardance V1 per UL 94.

Certifications listed are UL, CCC, CSA, Marine, UKCA, EAC and CB Scheme. Because the marine listing appears on the datasheet, the contactor is relevant to shipboard and offshore panels, subject to the approval details of the specific installation.

Where the LC1D09M7 is used in Oman and the GCC

Small three-phase motors up to 4 kW at 400 V are everywhere in the Gulf: circulation pumps, dosing pumps, extraction fans, conveyors and small compressors. The LC1D09M7 is the commodity starter element for these, and its 50/60 Hz coil allows the same unit to serve both 50 Hz local panels and imported 60 Hz equipment.

Hot switchrooms demand attention to ambient derating above 60 °C, and dusty sites need clean enclosures with filters on the ventilation.
