The Square D 8903SM02V02 Lighting Contactor is a versatile and reliable electrical component designed for controlling lighting loads. This contactor is part of Square D's popular 890 series, known for its superior performance and durability.
This contactor is a 2-pole, 3-position, 2-way device, which means it can be used to control single-phase AC lighting circuits. It offers three functional positions: Normally Open (NO), Normally Closed (NC), and Common (COM). When in the NO position, the contacts are open when the coil is de-energized. In the NC position, the contacts are closed when the coil is de-energized. The COM position is the middle position, where the contacts are connected to each other and the load when the coil is energized.
The contactor features a robust construction with a silver-alloy contact material and a gold-plated secondary contact. These materials ensure excellent electrical conductivity, long contact life, and minimal wear and tear. The contactor is also designed to handle inrush currents up to 600% of its rated current for a short duration without tripping.
The Square D 8903SM02V02 Lighting Contactor provides overload protection with its built-in thermal magnetic trip unit. If the current flowing through the contactor exceeds its rated value, the trip unit will activate and disconnect the load to prevent damage or overheating. This contactor is also rated for operation in temperatures ranging from -40 F to 140 F (-40 C to 60 C), making it suitable for various environmental conditions.
This contactor is designed to be easily installed and integrated into electrical systems. It measures 4.6 x 2.2 x 1.1 inches (116.8 x 55.9 x 27.9 mm) and has a mounting depth of 1.2 inches (30.5 mm). It can be mounted on a DIN rail or a backbox, allowing for easy mounting and wiring. The contactor also comes with a coil voltage rating of 120VAC and a current rating of 15A at 125VAC.
In summary, the Square D 8903SM02V02 Lighting Contactor is a high-performance, versatile, and durable electrical component ideal for controlling single-phase AC lighting circuits. It offers excellent contact life, overload protection, and easy installation, making it a popular choice for various industrial, commercial, and residential applications.
