Bussmann Series Disconnect Switches UL 98/UL 508

Enclosed rotary disconnects from the Bussmann series offer a simple installation method for adding a power switch. Enclosed compact circuit protectors (CCPs), which are available for 30 amp Class CC fuses and up to 60A for class CF fuses, are among the smallest solutions on the market for boosting protection and panel SCCR. Additional UL 98 choices include Class L fused options up to 800A and non-fused options up to 1200A. For control and disconnecting purposes for motor applications, use UL 508 load break disconnects.

Features-

• Uses UL Class CF time-delay or fast-acting CUBEFuse with Class J electrical performance.

• Extremely compact design at 25.4 mm (1 inch) wide per pole.

• Amp rating rejection disconnects will not accept a CUBEFuse amp rating greater than switch rating.

• High 200 kA short-circuit current rating.

• Disconnect rated to provide means for load isolation.

• Full voltage rated at 347 Vac (1-pole switches) and 600 Vac (2- and 3-pole switches).

• 125 Vdc* rated to meet specialized applications.

• UL 98 Listed and suitable for branch circuit disconnect and branch circuit protection with installed fuses.

• Horsepower rated.

• Open fuse indication:.

• Local open fuse indication light standard on each pole.

• Optional PLC fuse monitor for wired remote open fuse indication by signaling a PLC and opening a contactor to de-energize all phases, if required.

• Additional open fuse indication can be provided by the indicating time-delay CUBEFuse (6 to 100 A).

• Finger-safe construction with 10 AWG (6 mm2) wire or larger.

• Built-in switch interlock prohibits removing or installing the fuse while in the ON position.

• Padlockable for lockout/tagout procedures with a 1/4” lock.
