Commercial & Logistics Data
Country of Origin: United States (USA) or Poland (reflecting regional factory lines for ABB/GE heavy electrical components)
Customs Tariff Number (HS Code): 8536490000 or 85365080 (Electrical switches, relays, and contactors rated for a voltage exceeding 60V but not exceeding 1000V)

Electrical & Performance Ratings
Number of Poles: 3-Pole (Designed for 3-Phase balanced electrical power networks)
Maximum Operational Voltage: Up to 600V AC (Standard US industrial limitation) / 690V AC (International IEC compliance rating)
Continuous Current Rating (AC1): Up to 700 to 1000 Amperes maximum thermal current capacity depending on ambient heating conditions.
Motor Load Capacity (AC3 Application): Explicitly rated up to 300 HP at 460V/600V AC (3-Phase) or up to 375 kW at 380V/400V AC.
Control Coil Specifications: Equipped with an electronic-module supported wide-range control coil accepting 110-127V AC (50/60 Hz) / DC inputs.
Integrated Auxiliary Terminals: Configured natively with 1 Normally Open (NO) + 1 Normally Closed (NC) auxiliary monitoring block for safety feedback loops.
Environmental Limits
Operating Ambient Temperature: -25°C to 55°C (-13°F to 131°F) under continuous full-load conditions.
Storage Temperature Range: -40°C to 70°C (-40°F to 158°F)
Relative Humidity Protection: 5% to 95% non-condensing atmosphere.
Operational Sound Level: Generates a quiet physical running noise footprint of approximately 45 dBA during locked seal actuation.
Key Features and Characteristics
Arc Chute Suppression Design: Integrates segmented, heavy-duty cooling arc chutes over each pole to absorb high-voltage plasma flashes, rapidly extinguishing electrical arcs and extending the lifecycle of internal contacts.
Premium Alloy Contacts: Constructed using oversized 90% Silver and 10% Cadmium Oxide composite alloy contact pads to resist pitting, prevent contact welding, and guarantee over 1 million electrical under-load operations.

High Fault Current Security: Built to easily withstand extreme electrical short-circuit fault stresses when paired alongside correctly coordinated upstream fast-acting fuses or industrial circuit breakers.
Electronic Coil Management: Features an integrated coil control module that handles high inrush pulling energy smoothly and silently drops down to lower holding power consumption levels once the magnetic poles seal, avoiding common AC hum and vibration.
Robust Mechanical Lifespan: Rugged internal guide mechanics provide an ultra-long mechanical chassis lifespan rated for 10 to 20 million operations before requiring physical overhaul maintenance.
