Description
Designed for commercial power distribution, this 200A MCCB utilizes a B-C phase connection to balance loads across the bus. It delivers reliable long-time and instantaneous trip functions. This component mounts into Square D I-Line panelboards and switchboards. Facilities transitioning to current generation hardware can substitute this with the PowerPact JGA262004. With a 65kA interrupting rating at 240V, it provides robust fault protection and carries an HACR rating for mechanical systems.Specifications

Product FAQs
6 answersWhat does the BC suffix indicate on the KH26200BC circuit breaker?
The BC suffix specifies the phase connection. It indicates that this 2-pole breaker is configured to connect to the B and C phases of a Square D I-Line busbar system.
What is the modern replacement for the legacy Square D KH26200BC?
The KH26200BC is part of the legacy K-Frame series. Facilities upgrading to current generation hardware can substitute this breaker with a 200A Square D PowerPact J-Frame breaker configured for I-Line panels, such as the JGA262004.
How does the trip unit operate on the KH26200BC?
This breaker utilizes a thermal-magnetic trip unit providing long-time and instantaneous (LI) protection. The thermal overload protection is fixed, while the magnetic short-circuit protection is adjustable, allowing electricians to fine-tune the instantaneous trip threshold for specific loads.
How does the KH26200BC mount into a panelboard?
It features an I-Line style plug-in connection. The breaker has plug-on jaws on the line side that snap directly onto the busbar of a Square D I-Line panelboard or switchboard, while the load side uses standard mechanical lugs.
Is the KH26200BC suitable for direct current (DC) systems?
Yes, in addition to its AC ratings, this breaker is rated for DC power distribution. It can safely interrupt faults up to 10kAIC in 250VDC applications.
Is the Square D KH26200BC rated for use with HVAC equipment?
Yes, this breaker carries an HACR (Heating, Air Conditioning, and Refrigeration) rating, making it suitable for protecting mechanical systems and motor loads in commercial environments.
