Description
Part of the Square D I-Limiter family, the IF36070 3-pole, 70A MCCB is built for industrial environments. It provides thermal-magnetic protection with fixed LI trip functions. This unit installs into Square D I-Line panelboards using a plug-on connection. For modern upgrades, this legacy IF-frame is replaced by the HRA36070. Delivering 200kAIC at 480VAC, this current-limiting breaker actively restricts let-through energy during a fault to minimize stress on downstream components.Specifications

Product FAQs
4 answersWhat type of panelboards accept the IF36070 circuit breaker?
This breaker is designed specifically for Square D I-Line panelboards. It utilizes an I-Line plug-on connection that engages directly with the panelboard bus assembly.
What does the current-limiting feature of this breaker do?
As a current-limiting breaker, it actively restricts the peak let-through current and energy during a short circuit fault. This rapid clearing action minimizes thermal and mechanical stress on downstream electrical components.
What is the modern replacement for the legacy IF36070 breaker?
The IF-frame is a legacy Square D product. For modern upgrades or new installations requiring the same 70A capacity and 200kA at 480V interrupting rating, it is replaced by the PowerPact H-frame series, specifically catalog number HRA36070.
Are the thermal and magnetic trip settings adjustable on this breaker?
No, the IF36070 features a thermal-magnetic trip unit with fixed long-time and fixed instantaneous functions. The trip settings cannot be adjusted in the field.
