Moeller FAZ Miniature Circuit Breaker (Protection of Modern Power Supplies)

The Moeller FAZ line of miniature circuit breakers (FAZ-NA) are ideal for protection of power supplies, control power transformers, HVAC, refrigeration equipment, florescent lighting (to 20A) and numerous applications requiring a protective device

Sept. 7, 2012 - PRLog -- Moeller FAZ Circuit Breakers are available in one, two and three-pole configuration with 20 different current rating ranging from 05 up to 40A. All breakers are available in both C and D tripping curves, providing protection from 5 to 10 and 10 to 20 x the continuous rating of the device (In). The Moeller FAZ range offers short-circuit ratings of 10kA regardless of voltage applied.

Moeller FAZ Circuit Breakers are available in two terminal configurations: standard box terminal which accept multiple conductors and ring-tongue terminals ideally suited to demanding requirements of the semiconductor industry. All FAZ breakers mount on standard 35mm DIN-rail. Bus Connectors and Feeder Terminals facilitate mounting and wiring of multiple miniature circuit breaker arrays. Power to the FAZ circuit breakers can be fed from the line or load side.  

Enhanced Safety Features: Moeller FAZ

Moeller FAZ Circuit Breaker terminal provide finger and back of hand protection to guard against accidental contact with live parts. FAZ breakers incorporate a “trip free” mechanism to prevent trip function from being defeated by holding the operator in the ON position. FAZ Circuit Breakers are UL listed and CSA certified for fuseless protection of smaller AWG 18 and 16 conductors. A colour coded red/green indicator provides immediate visual indication of device status and isolation function.    

Moeller FAZ Tripping characteristics
The Moeller FAZ-NA(RT) Circuit Breakers are available with “C” and “D” tripping characteristics. C-curve devices are suitable for applications where medium levels of inrush current are expected. Applications include small transformers, lighting, pilot devices, control circuits, and coils. C-curve devices provide a medium magnetic trip point.

Devices with a "D" curve are suitable for applications where high levels of inrush current are expected. The high magnetic trip point prevents nuisance tripping in high inductive applications such as motors, transformers, and power supplies.  

The Moeller FAZ-NA(RT) device are also current limiting, meaning they interrupt fault current within one half cycle of the fault. Current limiting devices offer superior protection by reducing peak let-through current and energy.

Typical Application use of Moeller FAZ:
Feeder and Branch Circuit Protection
• Convenience receptacle circuits (internal/external)
• Motors  (internal/external)
• Load circuits leaving the equipment (external)
• HACR Equipment (Heating, Air Con-ditioning, Refrigeration) (internal/external)

Main Features:
• Current limiting
• SWD (switching duty) – suitable for switching fluorescent lighting loads (In ≤ 20 A)
• Fulfill UL 489, CSA C22.2 No. 5 and also IEC 60947-2 Standard
• For use in application for which UL 1077 or CSA C22.2 No.235 are also allowed
• Shunt trip release and auxiliary switch for subsequent mounting
• Separate Version for Ring Tonque Connection (Type FAZ-….-RT), terminal screws can be removed (on both sides)
• Module width of only 17,7 mm (per pole)
• Contact Position Indicator (red/green)
• Easy installation on DIN rail
• Possibility for sealing the toggle in on- or off-position

Moeller FAZ Supplementary Protectors

The Moeller FAZ range of Miniature Circuit Breakers includes a wide selection of supplementary devices / protectors. Specified to end user applications, the FAZ Circuit Breakers are typically used for control circuits, lighting, business equipment, appliances and a range of application where “closer” protection is desired than by a branch circuit protection device.

Moeller FAZ Extensive product range
Moeller Supplementary Protectors are available in one, two and three pole configurations and up to 17 different current rating from 0.5A to 63A. One pole plus neutral, and three pole plus neutral devices are available. Six different trip characteristics including B, C, D, K, S and Z curves provide the ability to configure the exact protection required. Devices can be used in applications up to 480V AC and 125V DC with short circuit rating up to 10kA.

Moeller FAZ Installation
Moeller FAZ mounts on a standard 35mm DIN-rail. Each device has box terminals that accept multiple conductors. Bus Connectors and Feeder Terminal facilitate mounting and wiring of multiple miniature circuit breaker arrays in control panel assemblies. Power to the circuit breakers can be fed from the line or load side.

Moeller FAZ Supplementary Protectors are available with six different tripping characteristics, including Type B, C, D, K, S and Z. Definitions for each trip curve are contained on the ordering pages and can be used to determine the optimal characteristic for your application.
