JTECUL Supplemental JTEC489 Branch Rated

 

JTECUL MCBs are certified as ‘Supplemental Protectors’ to UL1077 (CSA

235) and are intended for the overload and short circuit protection of individual

control components. Supplemental devices are typically used on the load

side of branch circuit devices to ‘Supplement’ the branch rated device. They

are available in a wide range of current ratings and trip characteristics that

allow them to be matched to the protection requirements of individual control

devices.

JTECUL MCBs are also certified to UL508 as Manual Motor controllers and

can be used for direct across the line starting of individual or groups of

motors. They are marked ‘Suitable for use as motor disconnect’ to meet

emerging inspection requirements. They are not intended to be used in

applications requiring a Branch rated device.

JTECUL MCB’s can be matched with a wide variety of accessories

to expand their capabilities.

JTEC489 MCBs are approved to UL489 as ‘Branch Circuit’ overcurrent

devices. In addition to having the same capabilities of the supplemental MCBs,

they are also approved for use as a main incoming feeder or for field wiring

applications. High 10kA interrupting rating is maintained up to 63A.

They are available in a wide variety of amp ratings and trip curves so they can

be matched to the circuit requirements. JTEC489 MCBs can be used in place

of Supplemental protectors.

JTEC489 MCB’s are available with a wide variety of accessories to expand

their capabilities.
