LHL36250 - 250 Amp Circuit Breaker

LHL36250 - 250 Amp Circuit Breaker

Bring dependable protection and peace of mind to your electrical system with the LHL36250 molded case circuit breaker. Designed for demanding industrial or commercial installations, this three-pole unit delivers dependable overload and short-circuit defense while operating at up to 600 VAC or 250 VDC. Whether you’re upgrading a power distribution panel or designing a new load center, the LHL36250 offers the kind of rugged, dependable performance that keeps your operation running safely and smoothly.

Key Features and Benefits

• Thermal-magnetic trip unit: Offers accurate overload protection via thermal sensing, and instantaneous magnetic response for short circuits, helping prevent damage to circuits and equipment.
• High fault current handling: Rated for 25 kA interrupt at 600 VAC and 50 kA at 250 VDC, meaning it can suppress substantial fault currents without failure.
• Flexible mounting options: Supports both unit mount and I-Line configurations, so it adapts to varied installation layouts and termination styles.
• Push-to-Trip button: Lets operators manually trip the breaker for testing or maintenance without opening the panel and exposing live components.
• Broad compatibility: Accepts lug connections on both line and load sides, with standard terminal identifier AL400LA.
