Description
Built for industrial OEM panels, this 15-ampere supplementary protector offers precise B-curve thermal-magnetic tripping. It is specifically engineered to shield sensitive circuits requiring low short-circuit tolerances. The device mounts easily onto standard DIN rails using secure screw clamp terminals. Note that this specific model has been replaced by the M9F21115. Featuring a trip-free mechanism, it maintains positive contact indication while limiting fault currents effectively.Specifications

Product FAQs
6 answersWhat product family does the MG17406 belong to?
The MG17406 is part of the Schneider Electric and Square D Multi 9 C60N series. It is a miniature supplementary protector commonly used in OEM panels and industrial control equipment.
What is the trip curve designation for the MG17406?
This breaker features a B-curve thermal-magnetic trip profile. B-curve breakers are designed for resistive loads or applications with very low inrush currents.
Can the MG17406 be used in direct current (DC) control circuits?
Yes, this breaker is dual-rated for both AC and DC systems. It supports DC applications up to 60VDC with a 10kA interrupting rating.
What type of wire connections does the MG17406 use?
It features screw clamp terminals that accommodate a wide range of conductors, accepting wire sizes from 14 AWG to 4 AWG for flexible installation in control panels.
Does the MG17406 serve as primary branch circuit protection?
No, the MG17406 is a UL 1077 recognized supplementary protector. It is intended to provide additional overcurrent protection within equipment where primary branch circuit protection is already installed upstream.
How is the MG17406 mounted inside an electrical panel?
This miniature circuit breaker clips directly onto a standard 35mm DIN rail, making it suitable for high-density DIN rail enclosures and automated control panels.
