WMZS Supplementary Protectors
Overview
The Eaton WMZS Supplementary Protectors
are used to provide overcurrent protection
where branch protection (for example, UL
489 MCCB) is already provided or not required. The units can be installed as a component within, or as a part of an appliance
or a piece of electrical equipment. Supplementary Protectors are ideal replacements
for fuses that are applied as a supplementary protector, i.e. in addition to branch protection (if required). They are 35 mm DINrail mountable, utilizing spring clips. These
are standard protectors, recognized by UL
and CSA under UL 1077 and CSA 22.2.
They are CE marked in accordance with
Low Voltage Directive (LVD) (73/23/EEC).
Product Specification
The WMZS Supplementary Protector is a
dual-rated product for both AC and DC
supplies, in accordance with UL 1077 and
CSA 22.2 standards and is marked with CE
in accordance with the Low Voltage Directive. With this dual standard product, you
can include it in your design, knowing that
in most cases wherever your equipment is
used, the product will conform to the local
UL, CSA or IEC (European) requirements.
The Supplementary Protector is designed
to be applied in conjunction with a branch
circuit protector (if branch protection is required) and can be a replacement for similarly applied fuses. Its advantage over fuses
is that it is resettable and the device’s status
is easily and clearly identified by the position of the handle and the flag indicator.
In addition, you can select a device that
provides maximum reliability and accuracy
to fit various applications due to the availability of a wide range of current ratings
from 0.5 to 63 amperes in three overcurrent characteristic curves, B, C and D.
Features and Benefits
• Box Terminals accept #18 to #4 wire
(1 to 25mm2) for one wire connection or
#18 to #8 for two wire connection.
• Thermal magnetic overcurrent
protection: three levels, categorized by
B, C and D curves in direct relation to
continuous rating of the device
B curve magnetic trip point:
3 to 5 times the rated current,
typically used for computers and electronic equipment with very low inrush
loads (PLC wiring).
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 loads
with very high inductive loads.
• Trip Free Design: Breaker cannot be
defeated by holding the handle in the
“ON” position.
• Color coded status indicator window –
Red = ON or Green = OFF
• IP20 finger protection
• 35 mm DIN-rail mountable, utilizing
spring clip
• Reverse Feedable
Listings
• UL recognized under UL 1077
Category QVNU2 File E162396
• CSA 22.2, No. 235 File 245545
• CE File LVD 2006/95/EC
• IEC/EN 60898
• IEC/EN 60947-2
Applications
WMZS Supplementary protectors are
recognized per UL 1077 and certified
per CSA C22.2 No. 235 as a Supplementary Protector and can be fully
utilized per the NEC and CEC Codes
in that capacity. For international purposes, the entire WMZS family is CE
marked and in full conformity with the
applicable IEC standards for miniature
circuit breakers, EN/IEC 60898 and
IEC/EN 60947-2.
Outside North America, they can be
used in both residential and industrial
applications as feeder and branch circuit protective devices. In North America, most European Miniature Circuit
Breakers are only UL recognized and
CSA certified as “Supplementary Protectors”, meaning they cannot be utilized
as feeder or branch circuit protective
devices per the local electrical codes
(NEC 240.10 and CEC Part 1 C22.1).
This commonly restricts their use to applications where “closer” protection is
desired than that offered by a branch
circuit protection device.
Eaton WMZS Supplementary Protectors are ideal for providing protection in
many applications, including:
• Control power transformers
• Relays
• Contactor coils
• PLC I/O points
• Lighting circuits
• Power supplies
• Computers
• Electronic equipment
