Nameplate identification and markings
It is always advisable to be familiar with the location and
information provided on a breaker’s nameplate. All low
voltage power circuit breakers must be applied within their
nameplate ratings. Nameplates are prominently displayed
on the front of the circuit breaker and provide important
information relative to that specific circuit breaker.
A Magnum PXR circuit breaker is easily identified by its
specific nameplate designation. Review the nameplate
example provided below.
1. Low voltage power circuit breaker family name
2. Breaker family designation number
3. Breaker frame size in amperes
4. Interrupting capacity rating
5. Factory equipped accessories (excluding shunt trip,
spring release, and UVR)
High performance interrupting
& withstand levels
Magnum PXR provides a large range of withstand and
interrupting ratings to maximize selectivity and system
coordination.
•
A range from 42 kA up to 100 kA interrupting:
Application on power distribution systems with higher
available fault currents.
•
Up to 100 kA withstand (short-time): Total selectivity/
selective coordination/discrimination between main,
feeder, and branch circuit breakers.
•
Current limiting performance: Lower let-through
currents for superior equipment protection.
•
Optional Arcflash Reduction Maintenance System
(ARMS™): Reduces arc flash hazards and improves
operator and maintenance safety.
•
Circuit breakers performance tested: Meet or exceed
all applicable ANSI, NEMA, UL, and IEEE standards.
Specifically, the circuit breakers meet or exceed the
following: UL 1066, ANSI C37.13, ANSI C37.16, ANSI
C37.17, ANSI C37.50.
Continuous current ratings
•
800 to 6000A – ensuring maximum uptime over expan-
sive frame rating range.
•
100% rated – designed for continuous operation at
100% of current rating.
•
Reverse feed capable – top or bottom feed for multiple
source applications.
