LS Electric ABN Moulded Case Circuit Breaker 63–1600A

The LS Electric ABN Moulded Case Circuit Breaker (MCCB) is LS Electric's primary low-voltage circuit protection device for medium and large current distribution applications, covering 63 A through 1600 A in a single consistent product family designed to IEC 60947-2 standard. The ABN range provides thermal-magnetic trip units in fixed and adjustable overcurrent settings, with breaking capacities from 25 kA to 100 kA (Icu) depending on frame size and variant — making it suitable for the full range of Saudi Arabia's industrial distribution applications from sub-distribution board feeders through to main low-voltage switchgear incomer protection and motor feeder protection in medium and large power industrial facilities. Frame sizes ABN 60c (63–100 A), ABN 100c (63–100 A enhanced), ABN 203c (125–250 A), ABN 403c (250–400 A), ABN 803c (500–800 A), and ABN 1603c (800–1600 A) cover the complete current spectrum with consistent accessories and trip unit interfaces.

The ABN thermal-magnetic trip unit provides overload protection via a bimetallic element with adjustable continuous current setting (Ir), and short-circuit protection via an electromagnetic element with fixed or adjustable instantaneous trip threshold (Im). Fixed trip versions are factory-calibrated and sealed for tamper-resistance in revenue metering applications; adjustable versions allow site-setting to match feeder conductor ampacity and coordination with upstream protective devices. The ABN is available in 3-pole and 4-pole versions for TN-S and TT earthing systems, covering the SEC earthing system requirements applicable to Saudi Arabia's industrial and commercial distribution installations. Accessories include auxiliary contact blocks, alarm contacts, motorised operators for remote operation, undervoltage trip attachments, and shunt trip coils for emergency trip-off circuit breaker applications in fire suppression and emergency shutdown panel designs.

LS Electric ABN MCCBs are specified by Saudi Arabia's SEC-licensed electrical contractors, panel builders, and engineering procurement companies as a cost-effective alternative to ABB Tmax and Siemens 3VA MCCBs for distribution protection applications in new construction and MRO replacement markets. Their IEC 60947-2 compliance, available breaking capacities up to 100 kA, and competitive SAR pricing — typically 20–35% below European equivalents at the same ampere and kA rating — make them increasingly prevalent in industrial MCCs, HVAC electrical panels, and infrastructure distribution boards across Saudi Arabia. The ABN is manufactured under LS Electric's ISO 9001:2015 quality management system with full factory test certification included with each device.

Razz Middle East maintains a broad ABN stock across all frame sizes and current ratings, with immediate availability on common specifications. We provide coordination study support, helping customers calculate the correct ABN rating for upstream/downstream circuit breaker coordination in compliance with Saudi electrical engineering practice. Volume pricing is available for project and panel builder orders.
