Schneider Electric LC1E0910M5 9 A 220 V AC Contactor

LC1E0910M5: 9 A AC-3, 220 V AC coil EasyPact TVS contactor

The LC1E0910M5 is a Schneider Electric contactor described in the datasheet as: EasyPact TVS contactor 3P(3 NO) – AC-3 – <= 440 V 9A – 220 V AC coil. It belongs to the Easy TeSys control range and is a three-pole device for switching motors and resistive loads. Seven Star LLC supplies the LC1E0910M5 in Oman and the GCC as an independent supplier based in Muscat.

Reading the reference: LC1E is the contactor family; the digits correspond to the 9 A AC-3 rating shown in the datasheet title, and the suffix gives the control coil, which the datasheet states as 220 V AC 50 Hz. A 220 V AC coil lets this contactor sit directly on a single-phase control circuit derived from phase and neutral of a 380/220 V supply, without any transformer. The 9 A rating suits small pumps, fans and auxiliary motors.

Technical specifications of the LC1E0910M5

Coil supply, inrush and drop-out of the LC1E0910M5

The coil is rated 220 V AC 50 Hz. The datasheet gives the operating window as 0.85 to 1.1 Uc and the drop-out as 0.3 to 0.6 Uc, which translates here to operation between 187 and 242 V and drop-out between 66 and 132 V. Control-circuit designers should check that voltage drop over long cable runs and during motor starting still leaves the coil above the pick-up limit.

At 50 Hz the inrush is 95 VA and the hold-in is 8.3 VA, which at the rated voltage is about 0.43 A and 0.038 A respectively. These are the figures a control transformer or PLC output must carry, and the datasheet operating times are 12 to 22 ms on closing; 4 to 19 ms on opening, so closing and opening are quick events compared with the run-up of the motor.

Power circuit ratings of the LC1E0910M5

For motor duty the datasheet lists AC-3 at 9 A and AC-3e at 9 A at up to 440 V AC (below 55 °C), and 25 A in AC-1 for resistive loads. The motor powers stated are 2.2 kW at 220/230 V, 4 kW at 380/400 V, and 4 kW at 660/690 V (with 5.5 kW listed at 660 to 690 V). The rated operational voltage of the power circuit is up to 690 V AC at 50/60 Hz.

Short-circuit data matter for coordination: the making capacity is 117 A, the breaking capacity is 76.5 A at 440 V, and the associated fuse for type 1 coordination is 20 A gG. Per-pole dissipation is 0.2 W AC-3; 1.6 W AC-1, and the average contact impedance is 2.5 mOhm, so heating in a closed panel can be estimated from these figures.

Selection checklist for the LC1E0910M5

• Motor current: compare the nameplate current with 9 A (AC-3) and, if the motor is high efficiency, with the AC-3e value of 9 A.
• Coil voltage: the control supply must be 220 V AC 50 Hz; the limits are 187 to 242 V.
• Overload protection: add a thermal overload relay or motor circuit breaker sized to the motor; the contactor itself does not give overload protection.
• Short-circuit protection: the datasheet quotes 20 A gG for type 1 coordination.
• Space: 45 mm wide, 74 mm high and 80 mm deep, 0.3 kg.
• Status: say whether you need a spare for an existing starter or a new installation.

Practical notes on choosing the LC1E0910M5

Confirm the actual control voltage on site: 220, 230 and 240 V circuits are not the same, and the coil operating window of 0.85 to 1.1 Uc defines how much deviation the contactor tolerates.

Contactors are often replaced under time pressure, so the safest approach is to read the full reference, the coil voltage and the frame from the old device and compare with the figures above. If the data on the nameplate and the datasheet disagree, send us the details and we will help to clarify before an order is placed.

Temperature, protection and certificates of the LC1E0910M5

The LC1E0910M5 is rated for -5 to 55 °C in operation and -60 to 80 °C in storage, with altitude up to 3000 m without derating. Protection is IP2X conforming to IEC 60529, so the device needs to be inside an enclosure. Mounting is on Plate or DIN rail. In Oman the upper limit of 55 °C is the figure to check against the real panel temperature in summer, because a closed panel in the sun can run far above the outdoor air.

Certifications listed for this reference are CB Scheme; CCC; CE; EAC; BIS. Only these should be assumed; if a project requires another approval, send the requirement and we will check it against the datasheet.
