Packaging & ESD

Industry-standard static shielding packaging is used for electronic components.Anti-static, light-transparent materials allow easy identification of ICs and PCB assemblies.
The packaging structure provides electrostatic protection based on Faraday cage principles.This helps protect sensitive components from static discharge during handling and transportation.


All products are packed in ESD-safe anti-static packaging. Outer packaging labels include part number, brand, and quantity for clear identification. Goods are inspected prior to shipment to ensure proper condition and authenticity.

ESD protection is maintained throughout packing, handling, and global transportation. Secure packaging provides reliable sealing and resistance during transit. Additional cushioning materials are applied when required to protect sensitive components.

Frequently Asked Questions

How does the C-trip curve of the Altech 2C10UL affect its suitability when protecting motor loads or circuits with moderate inrush currents in industrial control panels?
The Altech 2C10UL features a C-trip curve, which provides a magnetic trip threshold typically between 5 and 10 times the rated current. This characteristic allows the breaker to tolerate temporary inrush currents from motors, transformers, or capacitive loads without nuisance tripping while still delivering thermal protection against sustained overloads and magnetic protection for short circuits. In design scenarios involving inductive loads up to approximately 10A, engineers often select this model for branch circuit protection where the inrush remains below the instantaneous trip band for durations under 100 ms.
What are the key integration constraints for mounting and wiring the Altech 2C10UL on a standard 35 mm DIN rail in a control cabinet?
The Altech 2C10UL mounts directly on a 35 mm DIN rail and occupies 35 mm total width for its 2-pole configuration. Terminal connections accept 18-3 AWG on the top and 18-2 AWG on the bottom via box clamp style, with line/load reversibility. When integrating into dense panels, ensure adequate clearance for lever actuation and consider busbar accessories if multiple units share phases to reduce wiring complexity and potential contact resistance points.
Can the Altech 2C10UL be used in a 480Y/277V AC three-phase system, and what configuration considerations apply for balanced protection?
In 480Y/277V AC systems, the Altech 2C10UL is rated for use on two phases to provide protection up to 480 V between poles. For three-phase applications, designers typically deploy multiple 2-pole units or combine with single-pole variants depending on the neutral configuration and required protection scheme. Voltage derating or phase selection must align with the system's line-to-line potential to maintain the breaker's interrupting capacity rating.
What practical differences should engineers evaluate when considering migration from the obsolete 2CU10L to the Altech 2C10UL as a replacement part?
The Altech 2C10UL serves as a direct functional substitute for the 2CU10L in most DIN rail applications, maintaining the same 10A thermal-magnetic trip characteristics, 480 V AC rating, lever actuator, and 2-pole layout. The primary observed difference involves packaging and minor housing refinements in the UL series, with no required changes to mounting footprint or terminal accommodations. Verification of short-circuit interrupting capacity and end-use approval remains necessary during the migration to confirm system compliance.
How do ambient temperature variations in industrial environments influence the long-term thermal trip behavior of the Altech 2C10UL?
The thermal element in the Altech 2C10UL responds to the combined heating from load current and surrounding air temperature. At elevated ambients above the 40°C calibration point, the time to trip under overload conditions shortens, while colder environments extend it. In long-term installations exposed to temperature swings, engineers account for this shift by reviewing the breaker’s time-current curves adjusted for actual operating conditions rather than relying solely on nominal ratings.
Is the Altech 2C10UL appropriate for DC applications, and what voltage and pole considerations apply compared to pure AC use?
The Altech 2C10UL is primarily rated for AC operation up to 480 V in the UL series configuration. For DC circuits, the interrupting behavior and voltage withstand differ due to the absence of zero-crossing, typically limiting usable voltage per pole. Designers evaluating mixed AC/DC panels or battery-backed systems verify the specific DC rating from the series documentation and may require dedicated DC models to ensure reliable arc extinction under fault conditions.
What reliability factors should be reviewed when specifying the Altech 2C10UL for continuous operation in vibration-prone industrial machinery?
In environments with sustained vibration, the lever actuator and internal thermal-magnetic mechanism of the Altech 2C10UL benefit from secure DIN rail mounting and proper torque on terminals to minimize loosening. The breaker’s UL489 listing includes mechanical endurance expectations, but periodic visual inspection of the lever position and connection integrity helps detect any shift in performance over extended service intervals.
When replacing an existing 10A 2-pole breaker from another manufacturer with the Altech 2C10UL, what design implications arise regarding coordination and interrupting capacity?
Substitution with the Altech 2C10UL requires confirmation that the downstream device’s trip curve coordinates with upstream protection and that the available fault current at the installation point stays within the breaker’s interrupting rating. Differences in instantaneous trip tolerances or let-through energy between brands can affect selective coordination; engineers often perform a short-circuit study to validate the replacement maintains the intended protection hierarchy without introducing additional cascading risks.
