Schneider Electric LAB36175 I-Line Circuit Breaker

Schneider Electric LAB36175 I-Line Circuit Breaker is a 3-pole molded‑case protector designed to plug into I‑Line panelboards for three‑phase distribution. Rated at 175 A, it provides overcurrent protection with a thermal‑magnetic, non‑interchangeable trip unit, ensuring consistent response to short circuits and overloads. The LAB36175 handles voltages up to 600 VAC and up to 250 VDC, making it suitable for mixed AC/DC service in industrial or commercial power feeds. It features line and load lug terminals for straightforward wiring and offers interrupting ratings up to 22 kA at 600 VAC and 10 kA at 250 VDC, depending on the operating voltage. This plug‑in breaker is part of Square D’s LAB family designed for I‑Line panelboard ecosystems, enabling quick replacement or upgrades without rewiring. Typical applications include main feeder protection and branch protection for motors and equipment in three‑phase distributions where compact, code‑compliant protection is required.
