FDB1030S

The FDB1030S is a 1-pole molded case circuit breaker (MCCB) from Cutler Hammer, Eaton' Series C F-frame family, engineered for industrial and commercial power-distribution applications requiring dependable overload and short-circuit protection. Rated for 30 at 347, this compact breaker uses fixed thermal and fixed magnetic trip characteristics to provide consistent circuit protection for feeder, branch-circuit, and equipment applications. Electrically, the FDB1030S combines inverse-time thermal overload protection with instantaneous magnetic short-circuit protection through a non-adjustable thermal-magnetic trip system. It carries an interrupting capacity of , with the applicable rating determined by system voltage and installation configuration. This fixed-trip design provides straightforward protection without field-adjustable pickup settings, making the FDB1030S suitable for applications where predictable overload and fault response are required. Mechanically, the FDB1030S is built on Cutler Hammer, Eaton' Series C F-frame molded-case platform and is designed for installation in compatible distribution equipment, enclosures, and OEM assemblies. Its 1-pole construction provides coordinated circuit interruption across the protected conductors, while the compact F-frame housing supports space-efficient installation. The Series C FDB platform supports compatible line/load terminal arrangements and accessory options, allowing the breaker to be integrated into a range of commercial and industrial power-distribution systems. The breaker is UL listed for use in properly rated electrical equipment. Purchase the FDB1030S at Electrical.com, your reliable partner for industrial and commercial electrical products.
