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.
