IF36025

The IF36025 is a Square D I-Limiter current-limiting molded case circuit breaker in the IF series, rated for 25 amps at 600 volts with 3 poles, designed to protect circuits in industrial and commercial power distribution. With an interrupting rating of 100kA@600V, it is built for systems that can deliver very high fault currents. Its current-limiting design opens the circuit extremely quickly during a severe fault, which reduces the energy that reaches downstream equipment and helps protect conductors and other devices. The IF36025 uses a thermal-magnetic trip with a common trip across all three poles, so a fault on any pole opens all of them together. It provides long-time and instantaneous protection: the thermal element responds to sustained overloads, while the magnetic element trips instantly on a short circuit. This allows the breaker to clear a fault quickly and still tolerate the brief surges that equipment draws at startup. Mechanically, the IF36025 is an I-Line style plug-on breaker, which means it clips directly onto the bus in Square D I-Line panelboards and switchboards, making installation and replacement quick. Because Square D builds I-Limiter breakers in several series and ratings, it is worth confirming the part number, voltage, amp rating, and mounting against your equipment before ordering. This makes the IF36025 a practical choice for electricians and facility teams who need a high-interrupting, current-limiting breaker for an existing I-Line panelboard or switchboard.
