FD62B225 - 225Amp Circuit Breaker

FD62B225 - 225Amp Circuit Breaker

When you're replacing a circuit breaker, the small details matter. The amperage rating is the first thing most people check, but it is only part of the match. The breaker frame, voltage rating, pole configuration, interrupting capacity, trip type, and lug arrangement all need to line up with the equipment already in service.

The Siemens FD62B225 is a 225 Amp, two-pole molded case circuit breaker designed for FD-frame electrical distribution applications. It uses a thermal-magnetic trip unit to provide overload and short-circuit protection for compatible electrical systems. This breaker is rated for 600 VAC and provides an interrupting capacity of 22 kAIC at 600V and 35 kAIC at 480V.

Material Compliance and Certifications

The Siemens FD62B225 is designed to meet UL 489 and IEC 60947-2 standards for molded case circuit breakers. Before installation, verify that the breaker matches the equipment requirements, including frame type, voltage rating, pole count, interrupting capacity, trip characteristics, and lug configuration. Similar breaker models may have differences that affect fit and application, so checking the specifications before installation is an important step.

Where It Works Best

The Siemens FD62B225 is commonly used in commercial buildings, industrial facilities, manufacturing plants, and electrical distribution equipment requiring FD-frame circuit protection. It is a practical option for maintenance, repair, and replacement applications where the existing breaker ratings and connections need to remain consistent.
