Eaton FAZ Series MCBs
Eaton FAZ- miniature circuit breakers are Current limiting design provides fast short-circuit interruption that reduces the let-through energy that can damage the circuit, Trip-free design. Breaker cannot be defeated by holding the handle in the ON position
Features and Benefits
Thermal-magnetic overcurrent protection
Power to the circuit breakers can be fed from the line or load side
Clear indication of contact position via front switch toggle
Easy installation on DIN rail. Module width of only 17.5 mm (per pole)
Six levels of short-circuit protection, categorized by B, C, D, K, S and Z curves
Small modular width of the device and accessories saves space in the panel or equipment, which can lead to cost savings
Dual rated for IEC 60947-2 standard
Module widths: 1 Pole 17.5mm, 2 pole 35mm and 3 pole 52.5mm

Standards
IEC 60947-2 Relates to Low Voltage Circuit Breakers for use in industrial and similar
Installations. In the UK traditionally known as moulded case circuit breakers
(MCCB’s) and also air circuit breakers (ACB’s).

Q: What is the differences in the Tripping Curves B, C, D and S?
A: Curve B: Tripping: 3 to 5 times the rated current.
Applications: protection of generators, persons, very long cables
Curve C: Tripping: 5 to 10 times the rated current
Applications: protection of circuits and general applications
Curve D: Tripping: 10 to 14 times the rated current
Curve S Tripping 13 to 17 times the rated current
Suitable for applications where high levels of inrush current are expected. Instantaneous trip is 13–17X rating of device (In). The high magnetic trip point prevents nuisance tripping in high inductive applications such as motors, transformers and power supplies

Eaton Single-Pole MCB, 4A Current Rating, 10kA Breaking Capacity - FAZ Series - 278527 FAZ-B4/1
Features & Benefits
• Thermal and magnetic trip mechanism for overcurrent protection
• Modular design means it's easy to integrate with other safety devices and timers
• Red and green indicators on the front of the housing make it easy to read the device's status
• Circuit information printed on the MCB body to help reduce installation errors

How do I reset this MCB?
To keep people and circuits safe, this MCB won't let you simply override the fault by holding the toggle down. When the device trips, you'll need to identify and fix the problem. The MCB is then reset using the toggle switch on the front.
