Square D D222NRB - 60A, 2-Pole, Fused Safety Switch

The Square D D222NRB is a 60A, 2-Pole Fused Safety Switch engineered for reliable electrical isolation in demanding industrial and commercial settings. Designed to support proper lockout/tagout procedures, this switch provides a clear, safe disconnect path that protects personnel during maintenance while keeping equipment protected from fault currents.

Why this two-pole design matters: it isolates both hot legs for complete circuit de-energization, reducing the chance of accidental re-energization. The integrated fusing delivers immediate overcurrent protection at the source, helping limit damage to downstream components and extend the life of connected equipment. In tough environments, this combination delivers consistent performance and longevity.

Built by Square D, a trusted name in electrical safety, the D222NRB balances rugged durability with straightforward operation. Expect a solid enclosure that stands up to busy workshop floors and service rooms, with reliable switching action that technicians can depend on day in and day out. The design emphasizes easy wiring and quick maintenance, so servicing or fuse replacement doesn’t slow down critical operations.
