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.
Eaton Miniature Circuit Breakers (MCBs) - FAZ Series
The FAZ series of miniature circuit breakers (MCBs) from Eatons xEffect range has a current limiting design providing fast short-circuit interruption that reduces the let-through electrical energy and overload currents that can damage the circuit.
Ideally suited to control circuits and electrical distribution boards the FAZ series of MCBs offer a wide range of diverse protection characteristics, protecting your electrical equipment against overload damage. For additional safety, the MCB breaker cannot be defeated by holding the handle in the ON position, these MCBs are also finger proof and have a trip-free mechanism.
These MCBs have both a thermal and electromagnetic release, with rated currents of 0.16 A up to 63 A and a switching capacity of 15kA or 10kA depending on the device type.
The FAZ series includes miniature circuit breakers, interlocks, busbars and snap-on accessories including auxiliaries and tripping modules.
Features and Benefits
• Thermal-magnetic overcurrent protection
• Power to the miniature 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. MCB module width of only 17.5 mm (per pole)
• Six levels of short-circuit protection, categorized by Type 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
• Available in single pole up to 4 pole
• Dual rating for IEC 60947-2 standard
• MCB Module widths: 1P 17.5mm, 2P 35mm and 3P 52.5mm
