HGL36040 - 40 Amp Circuit Breaker

HGL36040 - 40 Amp Circuit Breaker

Meet the HGL36040 from Schneider Electric: a high-performance, three-pole circuit breaker rated for 40 amps and engineered to safeguard your electrical distribution with precision. Designed for systems up to 600 VAC, it delivers an 18 kA interrupt capacity at 600 V AC and even higher ratings at lower voltages, making it an excellent choice for commercial and industrial settings. With thermal-magnetic trip protection and dual-break rotating contacts that reduce peak short-circuit current, the HGL36040 ensures dependable protection and fewer downtime risks. Installation is streamlined thanks to the unit-mount lug configuration and flexible snap-in terminal design—saving both time and inventory hassle. Built in compliance with global safety and environmental standards (UL, CSA, IEC 60947-2, CE, RoHS, REACh) and part of the “Green Premium” program, this breaker blends high performance with a sustainable footprint.

Key Features and Benefits

• High Interrupt Capacity: Rated at 18 kA at 600 VAC, and up to 65 kA at 240 VAC, the HGL36040 stands ready for severe fault events.
• Thermal-Magnetic Trip Protection: Provides accurate overload and short-circuit detection in each pole for dependable system protection.
• Dual-Break Rotating Contacts: These reduce the peak inrush current during short-circuit faults—improving the safety margin for your equipment and wiring.
• Flexible Installation Design: Unit-mount lug configuration supports both line and load lugs, and the snap-in terminal design means easier conversions and less stocking of variants.
• Environmental & Safety Compliance: The product is RoHS- and REACh-compliant, CE-marked, UL and CSA listed, and part of Schneider’s Green Premium range—great for projects where sustainable design matters.
