Description

1. Unboxing & Physical Snapshot

• Model & Brand: General Electric / GE Spectra E150 Line — Molded Case Circuit Breaker (THED136100WL).
• Physical Dimensions: Approximately 105mm x 160mm x 85mm (compact molded insulated case envelope).
• Estimated Shipping Weight: 3.2 kg (heavy thermoset resin composite housing and internal high-conductivity copper primary current paths).
• What’s in the Box: Molded case circuit breaker unit, line/load terminal lug connectors, factory calibration seal sticker, and technical instruction leaflet.

2. Product Introduction

Environmental hook: Protecting critical power distribution networks from short circuits and thermal overloads requires robust switching hardware engineered to survive severe electrical fault transients. The heavy thermoset composite enclosure defends internal arc chutes and trip mechanisms against aggressive industrial atmospheres, which is critical for continuous-duty manufacturing plants.

Mounting securely directly into main switchboards or motor control centers, this 100-amp device manages branch feeder isolation safely. Reliability engineers rely on its precise thermal-magnetic trip curves to isolate faulted zones instantly while avoiding nuisance trips, maintaining strict compliance with plant safety uptime mandates.

3. Core Technical Specifications

4. Global Compliance & Industry Certifications

• Regulatory Approvals: UL Listed (UL 489), CSA Certified, CE Mark, and NEMA AB 1 compliance.
• Safety Standards: Conforms to strict international standards for low-voltage switchgear and controlgear assemblies.
• Compliance Significance: The UL Listed certification guarantees that internal creepage distances and interrupting capability ratings protect against catastrophic arc flash incidents under heavy fault conditions.
• Audit Note: Verify specific lot certifications and interrupting ratings with OEM documentation prior to final switchboard energization.

5. Long-Term Storage & Asset Preservation Guide

When storing high-interrupting molded case breakers in warehouse inventory, prioritize mechanical and environmental preservation. Keep the device sealed inside its original moisture-resistant protective wrapping to prevent dust or metallic particulate contamination from entering the internal operating toggle mechanism.

Maintain warehouse relative humidity below 60% to prevent oxidation on the internal copper contacts and external terminal lugs. Cycle the mechanical toggle switch manually once per year to keep internal spring assemblies and trip latches fully lubricated and free from binding.

6. Physical Installation Prerequisites

• Clearance Requirements: Leave adequate spacing around the breaker terminal compartments to accommodate heavy-gauge power cabling without applying mechanical strain to the molded resin housing.
• Torque Specifications: Fasten all line and load copper busbar connections using a calibrated torque wrench to the exact foot-pound specifications printed on the front faceplate to prevent high-resistance joint heating.
• Mounting Security: Bolt the unit securely to the panel backplate or breaker mounting rail using hardened steel mounting hardware to withstand heavy electrodynamic forces during short-circuit clearing events.

7. Buyer’s FAQ (Logistics & Compliance Focus)

• Q: What Harmonized System (HS) Tariff Code governs global customs processing for this circuit breaker?
  • A: Generally classified under HS code 8536.20 (Automatic circuit breakers for a voltage not exceeding 1000V); verify precise classifications with your customs broker.
• Q: Does this hardware component arrive with factory calibration documentation?
  • A: The unit undergoes strict factory thermal-magnetic calibration testing during production; individual test certificates can be requested via authorized supply channels if required for nuclear or strict QA applications.
• Q: How does the Country of Origin (COO) declaration impact cross-border tax compliance?
  • A: Typically manufactured in certified North American or European production facilities, the COO documentation establishes eligibility for regional trade preferences; request certificates prior to shipment dispatch.
• Q: What specialized transport insurance protects this electrical hardware asset?
  • A: Secure comprehensive “All-Risk” transit insurance with impact indicator tags affixed to the exterior shipping carton to monitor rough freight handling.
