Description
FUSERBLOC UL units are manually-operated multipole fuse load break switches with external right front-side operation and comply with UL and CSA standards.
- They provide make and break on load and safety isolation and protection against overcurrent for any low voltage electrical circuit
- The switches use double-pole isolator contacts to ensure complete isolation of the fuse when the switch is in the “OFF” position
- These devices are suitable for use as disconnectors for motors and industrial control panels on service entrance equipment, final panelboards, distribution switchboards, industrial
control equipment or motor control centres - This range is available in right front-side, direct or external control, in 2, 3 and 4 poles and up to 800 A
- Advantages
- Improved safety: The double phase isolator (upstreamdownstream of the fuse) and fully visible isolation guarantee the safety of people and equipment against overcurrents
- High breaking capacity: High breaking capacity fuses (200 kA rms) provide protection against overloads and shortcircuits
- Multi-use:
- The device can be equipped with a “Flange” type front or side operation handles, fitted directly on the product or externally, with the possibility of installing it on the door or the side of the electrical box or cabinet
- The device is also equipped with voltage measurement terminals for taking measurements as well as an NFPA 79 compliance kit available as an option
- Simplified use:
- The TEST position enables testing of the control circuits without turning on the power thanks to the use of U-type auxiliary contacts
- In the TEST position, the cabinet door can be opened
- Handle not included
