Description
Features
- The M9F42101 is a 1-Amp, single-pole, DIN-rail mounted miniature circuit breaker (MCB) from Schneider Electric's Multi9 C60BP series. It is a high-performance, multi-standard breaker specifically designed for OEMs (Original Equipment Manufacturers) and control panel builders who need precise protection for low-current circuits.
- Because of its very low 1-Amp rating, this breaker is not for general lighting or power outlets. Instead, it is used to protect sensitive components in industrial control panels, such as: PLC Inputs/Outputs: Protecting delicate programmable logic controller circuitry. Control Transformers: Providing branch protection on the secondary side. Sensors and Transmitters: Safeguarding expensive instrumentation. Power Supplies: Individual protection for small DC power units.
- The C Curve designation means the breaker will trip instantaneously when it senses a current between 7 and 10 times its rated load (AC). This makes it ideal for circuits with moderate "inrush" currents, such as small solenoids or control relays, where a "B" curve might trip too easily but a "D" curve would be too slow.
- The C60BP line is "Multi-Standard," meaning it carries several global certifications in a single unit. It is CSA C22.2 No. 5 and UL 489 listed, making it fully legal for use as a "Branch Circuit Protector" in Canada and the USA. This is a significant step up from "supplementary protectors" (like the UL 1077 series), as it can be used for primary circuit protection.
- Despite its small size, the M9F42101 is incredibly rugged: At 277V AC: It has an interrupting rating (AIR) of 10,000 Amps. At 120V/240V AC: It is rated for 14,000 Amps. DC Rating: It is also rated for 60V DC (10kA), making it versatile for both AC control circuits and DC power distribution.
