IEC

IEC is a brand of miniature circuit breakers (MCBs) and ground fault protectors (GFPs) manufactured by Eaton, a multinational power management company. The product line includes UL489-listed DIN rail-mount MCBs and UL1053-listed supplementary protectors designed for industrial and commercial electrical distribution systems. IEC-branded MCBs are available in C-curve trip characteristics, 4-pole configurations, and current ratings from 7 A to 10 A, with voltage ratings up to 480 V AC and interrupting capacities of 10 kA at 277/480 V AC. These breakers use screw-type terminals and are suitable for branch circuit protection in panelboards, motor control centers, and equipment disconnects. The ground fault protectors (GFP series) are DIN rail-mount devices with Type A residual current sensitivity, available in rated residual currents of 26 mA, 86 mA, and 260 mA, and current ratings from 25 A to 63 A at 240 V AC. Their interrupting ratings range from 1.5 kA to 10 kA at 240 V AC, depending on the model. These GFPs provide personnel and equipment protection against ground faults in applications such as heating equipment, pumps, and industrial machinery. 3G Electric stocks a range of IEC-branded circuit breakers and ground fault protectors, supporting global procurement with logistics for industrial buyers. The products are built to UL and CSA standards, with DIN rail mounting for standardized installation in control panels. Technical specifications—including voltage, current, interrupting capacity, and residual current—are clearly defined per SKU, enabling engineers and maintenance managers to select appropriate devices for specific system requirements. The brand's association with Eaton ensures consistent manufacturing quality and compliance with North American and international electrical codes.

Pertanyaan yang Sering Diajukan

Pertanyaan umum tentang IEC dari 3G Electric.

What are the key specifications of IEC FAZ-C series miniature circuit breakers?

The IEC FAZ-C series miniature circuit breakers are UL489-listed, DIN rail-mount devices with C-curve trip characteristics. They are available in 4-pole configurations with current ratings such as 7 A and 10 A. These breakers are rated for 480 V AC and have an interrupting capacity of 10 kA at 277/480 V AC. They use screw-type terminals for wiring connections. The FAZ-C series is designed for branch circuit protection in industrial and commercial electrical systems.

What is the difference between IEC UL489 miniature circuit breakers and UL1053 ground fault protectors?

IEC UL489 miniature circuit breakers (e.g., FAZ-C series) are designed for branch circuit protection, providing overcurrent and short-circuit protection with interrupting capacities up to 10 kA at 480 V AC. They are listed under UL489. In contrast, IEC UL1053 ground fault protectors (GFP series) are supplementary protectors that detect residual currents (e.g., 26 mA, 86 mA, 260 mA) and provide ground fault protection. They are rated for 240 V AC and have lower interrupting ratings (1.5 kA to 10 kA). GFPs are used in conjunction with overcurrent devices for personnel and equipment protection.

What are the available residual current ratings for IEC ground fault protectors?

IEC ground fault protectors (GFP series) are available with rated residual currents of 26 mA, 86 mA, and 260 mA. These are Type A devices, meaning they detect AC sinusoidal residual currents and pulsating DC residual currents. The specific residual current rating depends on the model: for example, SKU 482N46 (63 A) has 26 mA, SKU 482N40 (25 A) has 260 mA, and SKU 482N35 (25 A) has 86 mA. These ratings are suitable for different levels of ground fault sensitivity required in industrial applications.

Can IEC miniature circuit breakers be used in three-phase systems?

Yes, IEC FAZ-C series miniature circuit breakers are available in 4-pole configurations, making them suitable for three-phase, four-wire systems (e.g., 480Y/277 V AC). The 4-pole design allows simultaneous protection of all three phases and the neutral conductor. The breakers are rated for 480 V AC line-to-line and have an interrupting capacity of 10 kA at 277/480 V AC, which is adequate for many industrial three-phase applications.

What is the interrupting capacity of IEC ground fault protectors?

The interrupting capacity of IEC ground fault protectors varies by model. Some models, such as SKU 482N40 (25 A, 260 mA) and SKU 482N35 (25 A, 86 mA), have a maximum AIR rating of 10 kA at 240 V AC. Other models, like SKU 482N46 (63 A, 26 mA) and SKU 482N48 (40 A, 260 mA), have a lower interrupting rating of 1.5 kA at 240 V AC. The interrupting capacity should be matched to the available fault current at the installation point.
