Description
Part of the legacy K-Frame series, the Square D IK36150G is a 150A, 3-pole MCCB delivering thermal-magnetic protection with a factory-installed equipment ground fault module. Engineered for commercial power distribution, this unit mounts into Square D I-Line panelboards. It provides a drop-in replacement for aging infrastructure and is replaced by the KI36150G. Rated 200 kAIC at 480V, this current-limiting breaker minimizes let-through energy and features an adjustable magnetic trip.Specifications

Product FAQs
6 answersWhich panelboards are compatible with the IK36150G circuit breaker?
This breaker is designed specifically for use in Square D I-Line panelboards and switchboards. It features the I-Line plug-in mounting style for quick and secure phase connections directly to the busbar.
What is the modern replacement for the legacy IK36150G?
The IK36150G is a legacy K-Frame breaker that has been replaced by the KI36150G. Both models share the same I-Line mounting and 150A GFEP specifications for seamless integration into existing panelboards.
What type of ground fault protection does the IK36150G provide?
The G suffix indicates it includes integral Ground Fault Equipment Protection (GFEP). It utilizes a Long-Time, Instantaneous, and Ground-Fault (LIG) trip unit to protect machinery and equipment from damaging ground faults, rather than providing Class A personnel protection.
How does the current-limiting feature of the IK36150G benefit an electrical system?
As a current-limiting breaker, it clears severe short circuits extremely fast. This minimizes the peak let-through current and energy, reducing thermal and mechanical stress on downstream equipment during a fault.
Are the trip settings on the IK36150G adjustable?
The breaker features a thermal-magnetic trip unit with a fixed thermal element for overload protection and an adjustable magnetic element. This allows electricians to fine-tune the instantaneous short-circuit trip threshold based on the application.
Do I need to purchase a separate ground fault module for this breaker?
No, the IK36150G comes with a factory-installed ground fault module built into the unit, providing integrated equipment protection without the need to wire external relays.
