DK3250W - 250Amp Circuit Breaker

DK3250W - 250Amp Circuit Breaker

When dependable circuit protection is needed in an existing commercial or industrial electrical system, the Eaton DK3250W delivers the ratings and compatibility required to keep operations moving. This 250 Amp, 3-pole molded case circuit breaker is part of Eaton's proven Series C K-Frame product line and is designed for applications where maintaining original equipment specifications is important.

Whether you're replacing a damaged breaker during routine maintenance or sourcing a matching unit for an electrical distribution system, the DK3250W provides the form, fit, and function needed for seamless integration into compatible installations. Its T186 thermal magnetic trip unit helps protect equipment and conductors from overloads and short-circuit events, while the 65kA interrupting rating at 240 VAC makes it suitable for demanding commercial and industrial environments.

Because this breaker is supplied without terminals, it offers installation flexibility for applications that require specific terminal configurations. Rated for both 240 VAC and 250 VDC systems, the DK3250W is commonly found in switchboards, panelboards, distribution equipment, and feeder circuits throughout manufacturing facilities, commercial buildings, institutions, and other mission-critical operations.
