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

Standards

IEC 898; BS/EN60-898; EN50 022/DIN46277-3 (BS5584).

Eaton 2-Pole MCB, 4A Current Rating, 10kA Breaking Capacity - FAZ Series - 278726 FAZ-B4/2

Features & Benefits

• Screw terminals for a secure connection
• Line-side or load-side power feed for connection flexibility
• IP20 rating means it's touch-proof and safe to handle
• Not possible to override faults by holding the toggle down for increased safety of use

How easy is this MCB to use?

Once installed, this MCB is simple to use. It has red and green indicators underneath the toggle for quick status identification. The toggle switch itself means it's quick to turn a circuit off to carry out checks or repairs to the connected circuits.
