The Eaton Cutler-Hammer GHC3040 represents a reliable choice in molded case circuit breakers suitable for industrial applications. Weighing 1.7 lbs, this device maintains a robust design while offering an effective solution for electrical distribution. This unit is rated for a current of 40 amps and is structured with three poles to facilitate three-phase operation.
Operating at AC voltages of 480Y/277 VAC and 240 VAC, the GHC3040 can also handle DC voltages of 125/250 V. The circuit breaker provides an interrupting capacity of 14 kAIC at 480 VAC, ensuring it can manage short-circuit conditions effectively. For lower voltages at 240 VAC, it supports an interrupting rating of 65 kAIC.
The trip mechanism of this model utilizes fixed thermal and fixed magnetic functions, providing both long-time and instantaneous protection features. This enhances the safety of connected devices against overloads and faults. The GHC3040 operates efficiently within a frequency range between 50 Hz and 60 Hz, making it adaptable to various power systems.
