What is the difference between class CC fuses and Midget fuses for use in fuse blocks and fuse holders?
Class CC fuses are current limiting fuses that have one end "pinched down". CC-type holders have a restricted end that will only allow the pinched-end of CC fuse to fit into. A standard midget fuse won't fit into CC holder.
Midget fuses are defined as supplemental fuses and are not rated for current limiting. The CC style holders prevent this style of fuse from being inserted.
Refer to NEC 110-10 for more information on this subject.
FAQ ID: 891
The blown-fuse LED is not indicating when no fuse is installed in the dinnector?
Insure that the polarity is correct (I.E. the hinge is on the positive side.) Install fuses and finish the circuit as if ready to operate. When the system is known operational, power down and remove the power side only fuse. The LED should come on when the circuit is complete and has a load.
There is a lot of debate over fuse protecting the neutral (grounded conductor/white) conductor of a control circuit. The rule of thumb is to treat as a standard electrical circuit with no fuse on the neutral, only the hot. OPCD's, which open the hot and neutral simultaneously, fall under this category.
However, a system with an ungrounded secondary needs to have the neutral fused. If one shorts to ground without it, the system will have a major failure.
Refer to NEC articles 240 & 250.

What does the DIN mean on DIN rails and DINnectors?
DIN stands for "Deutsches Institut fur Normung", which means "German Institute for Standardization." In the 1970's the name DIN became the official symbol for technical standardization in Germany.
It has become commonplace for Automation equipment to be mounted on 35mm DIN rails. The DIN standard is used for normalization of mounting for everything from plc's to small drives industry wide in North America.
FAQ ID: 909
Are the BM series insulated wire ferrules UL listed?
The issue of UL recognition for ferrules typically comes from UL508A companies that inquire whether our ferrules are UL certified or UL recognized.
UL has not to our knowledge issued a set of standards related to regulation of wire ferrules for UL508A.
Once a stranded wire is inserted into the ferrule and crimped it makes the ferrule an integral part of the wire. It is no different than tinning the wire end with solder. As long as the diameter of the ferrule with the wire inside does not exceed the capacity for the connector it is placed in, the device should be able to pass UL approval.

What size screws are used in the DN series jumpers?
FAQ ID: 1252
What was re-designed on the Dinnector Terminal Blocks?
The jumpers system was changed from a screw down jumper bar to an insulated plug in jumper system.
FAQ ID: 1268
Why are the Dinnector Terminal Blocks being re-designed?
The plug in jumper system offers an insulated jumper.
The insulated jumper offers a better method to comply with IEC 60947-1 standard for clearance between conductive parts.
The plug in jumpers system is a faster and easier method of installing jumpers.
FAQ ID: 1269
What is the benefit of using the plug in jumpers verse the screw down jumpers system?
The plug in jumpers have the ability to be daisy chained by having (2) rows of holes for jumpers in the DN-T12 and DN-T10 series terminal block.
FAQ ID: 1270
Why would I use the DN-J2CUT and DN-J4CUT tool over diagonal cutters or other cutting pliers to cut the insulated plug in jumpers?
The DN-J2CUT and DN-J4CUT will allow the insulated plug in jumpers to retain insulation on the cut edges of the jumpers.
Diagonal cutters or any other cutting tools will remove the protective insulation on the jumpers.
FAQ ID: 1271
What is the temp rating for the BM Direct-mount terminal blocks?
They are rated to 105°C or 221°F
FAQ ID: 1287
What is the SCCR rating of DINnector terminal blocks?
They will have the UL508A default rating of 10kA per table SB4.1
