JTEC UL 489 Series
10kA Miniature
Circuit Breakers
Techna's
Jtec 489 range is UL 489 listed (File E255530). Available in trip curves
B (quick), C (medium), K (motor) and D (long delay) in current ratings
from 0.2 to 63A, and all available in 1, 2, 3 or 4 poles, Jtec 489 10kA
MCBs offer maximum
performance at excellent prices.
Benefits for Engineers and Designers
A. Jtec 489
is UL Listed as a branch circuit breaker and is therefore able to be
used to protect a branch circuit without a backup device.
Many applications and other UL standards insist upon the use of a branch
circuit breaker (as opposed to a supplementary protector). If you fit
the Jtec 489 you're covered!
B. Jtec 489
offers 10kA interrupt rating at 480Y/277VAC systems up to current
ratings of 32A, higher than most suppliers.
C. Jtec 489
maintains its 10kA interrupt rating right up to 63A when used on 240VAC
and 240/120VAC systems.
D. Jtec 489
is also available UL Listed up to 10kA in 250VDC ratings.
E. Jtec 489
also meets European standard EN60898 and EN60947-2 for circuit breakers
and is CE marked, ideal for manufacturers seeking to stock a single
product to use for global production requirements.
F. Jtec 489
has a full range of accessories. Auxiliary contacts with both changeover
and signal circuits - meaning you can remotely monitor the state of the
breaker (ON or OFF) and you can tell whether the breaker was manually
switched off or has tripped due to a circuit fault.
Shunt trip modules enable remote shutdown of the device.
The undervoltage release modules automatically switch off the breaker in
the event of a power failure, thereby protecting against an unexpected
machine start-up when mains power is restored.
Uniquely the N-pole (Neutral Pole) add on means you can convert a 3 pole
breaker into a 3 pole + switched neutral device with one shared
component, so you do not need to stock 4 pole devices, making inventory
savings.
Benefits for Service Engineers and Installers
A. Jtec 489
is suitable for field wiring - this means the product has been evaluated
by UL as being suitable for direct field installation by a field service
engineer (as opposed to factory fitted only.)
B. The
breaker terminal screws are recessed to provide finger touch protection.
C. Lockoff
adaptors are available to enable breakers to be padlocked on (to prevent
manual turn off), or locked off, for example by service engineers
working on the system.
D. The
breaker features a trip indicator window to show if the breaker has
tripped even if the handle has been inadvertently prevented from
movement. This saves a lot of time by enabling quick identification of a
tripped circuit when an engineer is on site.
