| Branch Circuit Breaker - General
Information |
| |
| Moeller has just expanded its FAZ line of
miniature circuit breakers to include devices that are listed and certified as
molded case circuit breakers per UL 489 and CSA 22.2, No. 5-02. These new
branch circuit breakers, called FAZ-NA and FAZ-RT, are ideal for the protection
of power supplies, control power transformers, HVAC, refrigeration equipment,
florescent lighting (to 20A) and many other applications requiring a primary
protective device. |
 |
|
| Flexible Product Range |
| Moeller’s FAZ Branch Circuit Breakers are
available in one, two and three pole configurations with 20 different current
ratings ranging from 0.5A to 40A. All breakers are available in both C and D
tripping curves, offering protection from 5 to 10 and 10 to 20 x the continuous
rating of the device (In). Two and three pole devices can be used in solidly
grounded circuits up to 480V AC. The entire line offers short circuit ratings
of 10kA regardless of voltage applied. |
| |
| Many installation options |
| FAZ Branch Circuit Breakers are available in two
terminal configurations; standard box terminals that accept multiple conductors
and ring-tongue terminals, ideally suited to the demanding requirements of the
semi-conductor industry. All breakers mount on standard 35mm DIN-rail. Bus
Connectors and Feeder Terminals facilitate mounting and wiring of multiple
miniature circuit breaker arrays in control panel assemblies. Power to the
circuit breakers can also be fed from the line or load side. |
| |
| Standard features enhance
safety |
| As with most products from Moeller, FAZ breaker
terminals provide finger and back-of- hand protection to guard against
accidental contact with live parts. A color-coded red/green indicator provides
immediate visual indication of device status and isolation function (green for
OFF, red for ON). All FAZ breakers incorporate a “tripfree”
mechanism. This prevents the trip function from being defeated by holding the
operator in the ON position. In addition, all FAZ branch circuit breakers are
UL listed and CSA certified for fuseless protection of smaller AWG 18 and 16
conductors! |

| Worldwide acceptance |
 |
| FAZ-NA (RT) Molded Case Circuit Breakers are UL Listed for
use in the United States in accordance with NFPA 70 (NEC). The devices comply
with UL 489 and CSA 22.2 No. 5-02, meeting the requirements for Molded Case
Circuit Breakers. These devices also comply with IEC 60947-2 and are CE
compliant. |
 |
| |
| Tripping characteristics |
| Moeller FAZ-NA(RT) branch 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. |
| Even though not required by NEC or CEC for Branch
Circuit Breakers, Moeller’s FAZ-NA(RT) devices are current limiting, which
means they interrupt fault currents within one half cycle of the fault. Current
limiting devices offer superior protection by reducing peak letthrough current
and energy. |
