8502SBO2V02 - Square D Magnetic Contactor

8502SBO2V02 - Square D Magnetic Contactor

The 8502SBO2V02 Square D contactor is a standard NEMA Size 1 unit used for switching motors, heaters, and similar loads. You’ll see it in a lot of control panels where a 3-pole, full-voltage contactor is needed. It’s rated for 27 amps up to 600 VAC, which covers most small to mid-size motor applications. This is a non-reversing contactor, so it’s meant for straightforward on/off control. The design is open-style, which makes it easier to wire and check during service. Screw clamp terminals keep connections simple and secure. It also carries a 100 kA SCCR when paired with the right protection, so it can be used in setups where higher fault current ratings are required. If you’re replacing a worn unit or matching an existing setup, this is a direct, no-surprises option.
