SQUARE D HU364RB U 200A 600V 3PH Non-Fused NEMA 3 Switch

Description

Product Overview

The SQUARE D HU364RB U 200A 600V 3PH non‑fused NEMA 3 current switch is engineered to meet the rigorous demands of modern industrial environments. Constructed from high‑grade alloy steel, the switch housing provides exceptional resistance to impact, corrosion, and thermal stress, ensuring a long service life even in harsh conditions. With a rated current of 200 amps and a voltage rating of 600 V, this three‑phase device delivers consistent, reliable performance for a wide range of applications, from motor control centers to heavy‑duty power distribution panels.

Designed to comply with NEMA 3 enclosure standards, the switch offers protection against dust, rain, and non‑hazardous liquids, making it suitable for both indoor and outdoor installations. The non‑fused design eliminates the need for additional fuse components, simplifying wiring and reducing overall system cost while maintaining safety through built‑in overload protection mechanisms.

Usage

Ideal for industrial facilities, manufacturing plants, and large‑scale commercial operations, the HU364RB switch integrates seamlessly into motor control panels, variable frequency drive (VFD) assemblies, and heavy‑duty circuit protection schemes. Electricians and maintenance technicians appreciate the straightforward mounting options—standard bolt‑on dimensions (19.3 x 8.2 x 31 in) and a weight of 44 lb provide a secure fit in most panel boards without the need for specialized tools.

Because the switch is non‑fused, it reduces inventory complexity and speeds up installation time. It is particularly valuable in applications where space is limited and rapid replacement is critical, such as emergency power systems, automated production lines, and high‑capacity HVAC units. The robust construction also tolerates frequent operation cycles, making it a dependable choice for equipment that experiences regular on‑off switching.

FAQ

What does non‑fused mean for this switch?

Non‑fused indicates that the switch does not require an external fuse for overload protection. The internal design includes built‑in mechanisms that safeguard the circuit, simplifying installation and reducing the number of parts needed.

Can this switch be used in outdoor panels?

Yes. The NEMA 3 rating provides protection against dust, rain, and non‑hazardous liquids, making it suitable for outdoor or semi‑outdoor installations where environmental exposure is a concern.

Is the HU364RB compatible with three‑phase motor loads?

Absolutely. The 3PH (three‑phase) rating is specifically intended for motor control applications, allowing the switch to handle balanced three‑phase loads efficiently.

What are the mounting dimensions and weight?

The switch measures 19.3 in × 8.2 in × 31 in and weighs approximately 44 lb, fitting standard panel board slots and providing a secure, stable installation.
