FAZ-NA Series Mini Circuit Breakers Overview

Features

Dual rated for AC or DC applications
Complete range of UL 489 listed DIN rail mounted miniature circuit breakers up to 63 ampere current rating
Single-pole, two-pole and three-pole models
Current limiting design provides fast short circuit interruption that reduces the let-through energy, which can damage the circuit
Suitable for branch circuit device protection
Trip Free Design: Breaker cannot be defeated by holding the handle in the "ON" position.
Captive screws cannot be lost
SWD (switching duty) rated circuit breaker
- Suitable for switching fluorescent lighting loads (In <=20A)
Fulfills UL 489, CSA C22.2 No.5 and also IEC 60947-2 Standards
Can also be used in applications for which UL 1077 or CSA C22.2 No.235 are also allowed
Field installable shunt trip and auxiliary switch subsequent mounting
Module width of only 17.7 mm (per pole)
Contact position indicator (red / green)
Mini DIN-rail circuit breaker
35mm DIN-rail mountable, utilizing spring clip
Suitable for reverse feed applications

Thermal magnetic overcurrent protection:

B-curve magnetic trip point: 3 to 5 times the rated current, typically used for resistive loads such as conductors or heaters.
C-curve magnetic trip point: 5 to 10 times the rated current, typically used for small transformers, pilot devices, etc.
D-curve magnetic trip point: 10 to 20 times the rated current, typically used for transformers or very high inductive loads.

Applications
