Siemens | HE2A003L | Circuit Breaker | 3A | 2-Pole | 480V

Siemens HE2A003L is a compact, two-pole circuit breaker designed for precise overcurrent protection in 480V electrical systems. With a 3 A rating, this device is tailored for circuits that require tight current control while safely interrupting fault conditions in industrial and commercial environments. This part number is the most reliable reference for matching compatibility, making it a dependable choice for maintenance, retrofit, or replacement projects where exactSpecs matter. What makes the HE2A003L stand out - Exact 3 A current protection: Prevents nuisance trips on sensitive feeders while safeguarding conductors and equipment from overloads. - Two-pole design: Ensures simultaneous disconnection of both supply lines, which minimizes arcing and enhances fault safety in 480V networks. - 480V compatibility: Suited for higher-voltage distribution panels common in industrial settings, delivering reliable protection where it’s most needed. - Siemens-verified reference: For best results, match this breaker to panels and enclosures that explicitly support the HE2A family and similar Siemens breakers. Key specifications at a glance - Part number: HE2A003L - Amperage rating: 3 A - Poles: 2-Pole - Voltage rating: 480 V - Intended use: maintenance, retrofit, and replacement in compatible Siemens panels Ideal use scenarios - Maintenance: Replace a failed or worn 3 A, 2-pole breaker in a 480V distribution path to restore protected circuits quickly and safely. - Retrofit: Upgrade or reconfigure an industrial panel that requires a precise 3 A 2-pole protection device with 480V capability. - Replacement: Substitute an older, incompatible breaker with the exact Siemens HE2A003L to maintain electrical code alignment and protective performance. Compatibility considerations - Confirm fit and ratings before ordering. The HE2A003L is designed for systems that accept HE2A-type breakers, so verify panel labeling and enclosure compatibility. - Use the part number as the primary reference when sourcing spare breakers to ensure correct trip characteristics and mechanical fit. Practical tips for installation and operation - Before installation, power down the associated panel and verify that the circuit’s current profile aligns with a 3 A protection device. - Inspect mounting rails and terminations for cleanliness and integrity to ensure a secure, fault-free connection. - When in doubt about compatibility, consult the panel’s documentation or Siemens support resources to confirm that the HE2A003L aligns with your specific 480V, 2-pole configuration. In short, the Siemens HE2A003L delivers precise 3 A protection in a robust 2-pole, 480V package, tailored for maintenance, retrofit, and replacement tasks in compatible panels. Rely on the exact part number to ensure a seamless fit and dependable performance in your critical electrical infrastructure.
