278551 FAZ-C3/1, Eaton xEffect MCB, 1P, 3A Curve C, 240V AC, 48V DC, 10 kA Breaking Capacity

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

Standards

IEC 898; BS/EN60-898; EN50 022/DIN46277-3 (BS5584).
FAZ-C*/* & FAZ-S*/* = IEC/EN60947-2

IEC 60947-2 Relates to Low Voltage Circuit Breakers for use in industrial and similar installations. In the UK these are traditionally known as miniature circuit breakers (MCBs), moulded case circuit breakers
(MCCBs) and also air circuit breakers (ACBs).

Eaton Miniature Circuit Breaker, 3A, 240V AC / 48V DC - FAZ Series - 278551 FAZ-C3/1

Swiftly detect and isolate electrical faults in your circuit with this single-pole MCB (miniature circuit breaker) from Eaton. It's designed with thermal and electromagnetic release functions to break a circuit quickly when there are dangerous short-circuits and high currents. Thanks to its type C characteristic, it trips instantly when flow-through current reaches between 5 and 10 times its 3A rating. It's easy to see when the device has been triggered as the front status indicator turns from green to red.

• DIN rail clip makes it easy to mount on standard systems
• Toggle switch can't be held in the 'on' position to override a fault, preventing unsafe use of circuits
• Recessed terminals are touchproof for added safety
• Narrow unit width of 17.5mm makes it easy to fit in tight spaces on panels

How do I connect this MCB?

This MCB uses screw terminals to make a straightforward and secure connection to your electrical circuit. The terminal points are clearly labelled for easy wiring, and the screws are captive so they can't be lost during installation.
