Description
Built for commercial and industrial distribution, the M9F21104 is a 1-pole, 4A supplementary protector from Schneider Electric's Multi 9 C60SP family. It utilizes a B-curve trip profile to quickly disconnect power during overcurrent events, protecting sensitive electronics. This unit mounts into standard DIN rail enclosures and serves as a reliable cross-reference for S201-B4 and FAZ-B4/1-SP breakers. It delivers a 14kA interrupting rating at 120/240VAC and is fully UL 1077 recognized.Specifications

Product FAQs
5 answersIs the Schneider Electric M9F21104 rated for supplementary or branch circuit protection?
The M9F21104 is part of the Multi9 C60SP series, which is designed for supplementary protection (UL 1077). It is ideal for protecting sensitive circuits within OEM control panels and equipment where branch circuit protection is already provided upstream.
What is the acceptable wire gauge range for the M9F21104 breaker terminals?
The screw clamp terminals on this miniature circuit breaker accept wire sizes from 18 AWG up to 4 AWG. This wide range provides flexibility for wiring within DIN rail enclosures and OEM control panels.
Can the M9F21104 miniature circuit breaker be used in DC voltage applications?
Yes, this thermal-magnetic breaker is rated for both alternating current (AC) and direct current (DC) systems. It supports DC applications up to 65VDC, where it provides a 10kA interrupting capacity, making it suitable for specialized control circuits.
How does the thermal-magnetic trip mechanism function on this Multi9 breaker?
The fixed thermal-magnetic trip unit provides Long-Time and Instantaneous (LI) protection. The thermal component responds to sustained overloads by heating and tripping the breaker, while the magnetic component responds immediately to high-current short circuits, ensuring comprehensive equipment safety.
How is the M9F21104 circuit breaker mounted inside a control panel?
This C60SP series breaker features a modular architecture designed for standard DIN rail mounting. This allows for quick, space-saving installation alongside other Multi9 or Acti9 components in DIN rail enclosures and OEM control panels.
