UL1077 UL508 UL489 They all look alike? What’s the difference?

UL1077- Supplementary Protector (SP) Only for overload protection!!! (has a thermal element inside)

UL508- Manual Motor Controller (MMC) Includes overload protection Includes switching function Includes disconnect function

UL489- Circuit Breaker (MCCB) (CB) Includes overload protection Includes switching function Includes disconnect function Includes short circuit protection

PRICING $ $ $ $ $ UL1077 $ UL508 $ UL489 $

Not by price!!! … but by: Selection Application Function Requirements by NEC or UL standards

Selection Devices may use a combination of all three types of protection devices. Fuses

Combination 1 Overload protection (SP) Switching function (MCCB) UL1077 - Supplementary Protection can be used in combination with a MCCB or a Fuse. Overload protection (SP) Switching function (MCCB) Disconnect function (MCCB) Short circuit protection (MCCB) Overload protection (SP) Short circuit protection (Fuse) Switching function Disconnect function

Combination 2 Overload protection (MMC) Switching function (MMC) UL508 - Manual Motor Controller can be used in combination with MCCB and a Fuse. Overload protection (MMC) Switching function (MMC) Disconnect function (MMC) Short circuit protection (MCCB) Overload protection (MMC) Switching function (MMC) Disconnect function (MMC) Short circuit protection (Fuse)
