Square D H362 - 60A, 600V, 3-Pole, Fused Disconnect Switch

The Square D H362 is a purpose-built fused disconnect switch that delivers dependable electrical isolation for demanding industrial and commercial applications. With a robust 60A rating and 600V capability across 3 poles, this switch is engineered to safely interrupt power in three-phase systems while supporting lockout/tagout procedures for maintenance and service. Built to endure daily use in rigorous environments, the H362 combines reliable disconnection with durable construction that stands up to long-term operation.

Key advantages of the Square D H362

• Precise three-phase isolation—3-pole design matches standard 3-phase equipment and wiring, enabling clean, simultaneous disconnection of all conductors.
• Fused protection—integrated fusing provides upstream fault protection, helping to limit fault current and safeguard downstream components and wiring.
• Safe, compliant maintenance—specifically designed to support lockout/tagout procedures, ensuring workers can service equipment without the risk of unexpected energization.
• Solid indoor enclosure—NEMA 1 enclosure rating offers reliable protection in dry, indoor environments typical of manufacturing floors, workshops, and commercial spaces.
• Durable, long-term performance—built for repeated operation under load, delivering consistent disconnection reliability when it matters most.
