SQUARE D FAL36100 1386 Product Description

Overview

SQUARE D FAL36100 1386 is a Square D FA/LA Series molded case circuit breaker from the Schneider Electric Square D low-voltage protection range. The base catalog model FAL36100 is a 3-pole, 100 A breaker rated for 600 V AC and 250 V DC systems, with thermal-magnetic trip protection and I-Line unit mounting. The 1386 suffix is treated here as a configuration, accessory, revision or internal spare reference for the breaker assembly; its exact meaning should be verified against the original Square D nameplate or Schneider order record. The breaker is used for branch, feeder, motor and distribution circuit protection in industrial and commercial electrical panels, and is traded as a replacement MCCB spare for existing Square D FA installations.

Features

SQUARE D FAL36100 provides 3-pole molded case protection with a thermal-magnetic trip unit. Continuous line rated current is 100 A, and the breaker supports system voltages up to 600 V AC and 250 V DC. The product belongs to the I-Line breaker range and uses unit mount installation, with lug connections on both line and load sides. Terminal identifier is AL100FA, accepting copper cable from AWG 14 to AWG 1/0 or aluminum cable from AWG 12 to AWG 1/0, one cable per terminal.

Interrupting ratings are 18 kA at 480 V AC, 25 kA at 240 V AC, 10 kA at 250 V DC, and 14 kA at 600 V AC. Magnetic hold current is 900 A, and magnetic tripping current is 1700 A. Phase connection is ABC. The breaker is UL listed and CSA certified. Package weight is approximately 4.83 lb, and country of origin is listed as MX. The product is categorized under Square D FAL/FHL 600V breaker material category and carries Schneider Green Premium, RoHS and REACH-related compliance status.

Principle

SQUARE D FAL36100 operates as a thermal-magnetic molded case protection breaker for three-phase electrical circuits. The thermal trip element responds to sustained overload current by heating and releasing the breaker mechanism over time, protecting cables and equipment from prolonged overload conditions. The magnetic trip element responds rapidly to high short-circuit or fault current, releasing the breaker contacts to interrupt the fault before equipment damage occurs. Magnetic hold current and magnetic tripping current define the threshold between normal inrush or starting current and instantaneous magnetic trip response.

The breaker is mounted as a unit in an I-Line panel or starter arrangement, with line and load lug terminals connected to the supply and protected circuit. Once a fault or overload trips the breaker, contacts open and the breaker must be reset after the condition is corrected. Protection settings, interrupting capacity and application must match the panel rating, conductor size, motor or load characteristics, and Schneider or Square D breaker application rules. The 1386 configuration suffix should be matched to the original breaker accessory, revision or wiring arrangement before replacement.

Applications

SQUARE D FAL36100 1386 is used in three-phase low-voltage distribution panels, motor control centers, feeders, branch circuits, industrial machinery, production lines, pumps and fans, compressors, conveyors, material handling, commercial electrical switchboards, utilities, water and wastewater, chemical and process plants, power distribution and equipment manufacturer panels. It provides thermal overload and short-circuit protection for 100 A class circuits in existing Square D FA or I-Line breaker installations. In panels originally equipped with this breaker, the unit serves as a direct replacement MCCB spare, compatible with the original I-Line mounting, lug wiring, pole configuration and panel protection rating.
