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

Is CA3-B0-34-640-1B1-C a good choice for motor starts, transformers, or power supplies with high inrush current?
CA3-B0-34-640-1B1-C uses a magnetic (hydraulic delay) trip element, so it is generally better suited to short inrush events than a purely thermal breaker. That makes CA3-B0-34-640-1B1-C a practical fit for motor starting, control transformers, and many switch-mode supplies if the startup current shape and duration stay within Carling’s trip curve. For loads with long acceleration time, repeated cycling, or unusually large inrush, validate against the actual current waveform rather than relying only on the 40 A nameplate.
Can CA3-B0-34-640-1B1-C be used for both 480 V AC and 125 V DC systems without changing the design?
CA3-B0-34-640-1B1-C is rated for both 480 V AC and 125 V DC, but the wiring and interruption behavior of AC and DC circuits are not interchangeable. For DC use, confirm the actual fault current, conductor routing, and any manufacturer guidance on pole usage and connection method before finalizing the design. In practice, CA3-B0-34-640-1B1-C should be treated as a rated protection device for the specified system only when the installation follows the applicable DC application conditions.
What should I verify before replacing another 3-pole panel-mount breaker with CA3-B0-34-640-1B1-C in a retrofit panel?
When replacing an existing device with CA3-B0-34-640-1B1-C, match more than current and voltage. Check the panel cutout, mounting hardware, terminal style, conductor size compatibility, handle travel, and the breaker’s trip characteristic so the replacement does not change the way the load starts or trips. If the original device was thermal or had a different time-delay profile, CA3-B0-34-640-1B1-C may behave differently under inrush and overload conditions.
Is CA3-B0-34-640-1B1-C suitable for industrial control panels that run continuously in warm enclosures?
CA3-B0-34-640-1B1-C can be used in continuous-duty industrial panels when the enclosure temperature, ventilation, and load profile stay within the breaker’s application limits. Hydraulic-delay trip mechanisms are generally less sensitive to short ambient changes than purely thermal designs, but sustained heat, poor airflow, and repeated operation can still affect long-term behavior. For panels that run hot, verify temperature rise, wiring termination quality, and access for periodic inspection.
Can CA3-B0-34-640-1B1-C be used to protect PLCs, drives, or other sensitive electronics?
CA3-B0-34-640-1B1-C can be used as upstream branch protection feeding PLCs, drives, or power supplies, but it is not a substitute for point-of-load protection. For switch-mode supplies and drives, the main design check is whether the inrush, regenerative behavior, and fault coordination match the breaker’s trip response. In systems with sensitive semiconductors, CA3-B0-34-640-1B1-C is often paired with fuses or additional downstream protection rather than used as the only protective device.
What should I compare when selecting CA3-B0-34-640-1B1-C versus equivalent breakers from Eaton, Siemens, ABB, or Schneider Electric?
When comparing CA3-B0-34-640-1B1-C with equivalent parts from Eaton, Siemens, ABB, or Schneider Electric, focus on trip curve, inrush tolerance, interrupting performance, pole configuration, mounting envelope, and agency approvals rather than only the current rating. Two breakers with the same amp rating can still behave differently during motor starts, transformer energization, or fault clearing. For a true drop-in replacement, CA3-B0-34-640-1B1-C must also match the panel footprint and termination style used by the original design.
Does CA3-B0-34-640-1B1-C work well for three-phase loads, and what should I do about the neutral?
CA3-B0-34-640-1B1-C is a 3-pole breaker, so it is a natural fit for three-phase load protection where the three phase conductors should open and close together. It does not automatically address neutral switching requirements, so if your system is a 4-wire circuit, confirm whether the neutral must remain solidly connected or be switched by a separate design element. For mixed loads, CA3-B0-34-640-1B1-C should be applied only after checking the grounding and neutral architecture of the full assembly.
Are the UL, CSA, and CCC approvals on CA3-B0-34-640-1B1-C enough for an exported machine build?
The UL, CSA, and CCC approvals on CA3-B0-34-640-1B1-C help with component acceptance, but the finished machine still needs system-level compliance review. Final approval depends on enclosure temperature rise, wiring practices, short-circuit coordination, creepage and clearance, and the end-product standard in the destination market. In other words, CA3-B0-34-640-1B1-C can simplify certification work, but it does not replace validation of the complete panel or machine.
