Covers
Covers are included in the overall UL Listing/
Recognition and CSA Certification
IP20 finger-safe
RoHS Compliant
Poles:
1-, 2-, 3-pole units factory assembled
Single-pole units snap together to create
desired number of poles
Flammability ratings:
Blocks — UL 94V0, self-extinguishing
Covers — UL 94HB, self-extinguishing
Features and benefits:
Available in 1-, 2- and 3-pole configurations to
meet stocking requirements.
Blocks are fully modular with a snap-together
design that provides tool-less assembly of
multiple pole blocks at point-of-use to reduce
inventory and save assembly time and labor.
DIN-Rail and panel mount versatility allows one
product to be used for multiple applications,
lowering inventory cost.
Compact footprint consumes minimal panel
space.
Optional see-through cover enhances safety
with IP20 finger-safe protection, lockout/tagout
capability and open circuit indication.
Easy circuit identification with available universal
marker labels for fuse block covers.
Tin-plated bimetallic copper fuse clips deliver
superior fatigue resistance compared to
traditional spring brass.
Terminal options to meet application needs
including 1/4” spade quick connect terminals for
faster panel assembly.
Operating and storage temperature range:
Blocks -40°C to +120°C
Non indicating covers -40°C to +120°C
Indicating covers -20°C to +90°C*
* Indication requires minimum 90Vac/dc and
closed circuit to illuminate.
