Square D H362RB - 60A, 600V, 3-Pole, Fused Safety Switch

The Square D H362RB Fused Safety Switch is built for environments where safe electrical isolation isn't optional — it's essential. With a 60A current rating and 600V capability across three poles, this switch delivers dependable disconnection under load while supporting rigorous lockout/tagout procedures. Rugged and durable, it’s designed to stand up to the demands of industrial and commercial spaces where uptime matters.

Designed for safe, reliable isolation

As a fused safety switch, the H362RB provides integrated overcurrent protection right at the point of isolation. The three-pole design ensures all conductors are simultaneously disconnected, reducing arc exposure and streamlining maintenance workflows. The enclosure carries a NEMA 3R rating, making it suitable for outdoor installations and environments where rain, dust, or humidity come into play.

Key benefits
