Ferraz ATM1 1A 600VDC Features

THIS IS THE EQUIVALENT TO THE LITTEL FUSE 2 Amp Fuse

1-1/2" x 13/32" MIDGET FUSES

Amp-trap midget fast-acting ATM fuses are rated 600 volts AC, with a 100kA interrupting rating. These ratings give the ATM a wide range of applications not covered by other midget fuses. In addition, ratings of 30/35, 30/40 and 30/50 amperes are offered for specific applications such as capacitor protection. These ATM fuses must still be considered 30A fuses because of their dimensions, but are able to withstand much higher inrush currents and tougher duty cycles. (Not for branch circuit Protection).

• Fast Acting
• Special Ratings (above 30A)

Applications:

• Supplemental protection of a wide variety of circuits up to 600 VAC and 500 VDC with 100 kA I.R.

Features/Benefits

• For supplemental protection of small motors and transformers.
• Extended ratings for special protection of capacitors and circuits with high inrush currents.
• 500 VDC ratings for a wide variety of applications
• Can be used with ULTRASAFE^TM fuse folders

Ratings

• AC: 1/10 to 30A 600VAC, 100kA I.R.; 35 to 50A 600 VAC, 10kA I.R.
• DC: 1/10 to 30A 500VDC, 100kA I.R.

Approvals

• UL Listed to Standard 248-14 (1/10 to 30A)
• DC listed to UL Standard 198L (1/10 to 30A)
• CSA Certified to Standard C22.2 No. 248.14 (1/10 to 30A)

Weight: 0.01 lbs (0.0045 kg)
Dimensions: 1.5" x 0.406" (38.1 x 10.31 mm)

Wiley Electronics WEEB Grounding Lug Features

WEEBLugs meet UL467 when bonding to PV modules!

The patent pending WEEBLug consists of a washer and lay-in lug. The WEEBLug is mounted using a 1/4-28 stainless steel screw. Specialized teeth on the washer are constructed to embed into anodized aluminum and establish a gas-tight electrical connection. To obtain the lowest impedence path for the bonding connection, the washer is constructed of thin stainless steel. The current path through the aluminum, the teeth, the washer body and into the lug is therefore very short. The lug is constructed of tin plated copper for corrosion resistance. Wire is clamped by a stainless steel screw on the lug, which is horizontal to the tang for easy access when mounted under a PV module. The screw is a 1/4-28 size for easy wrenching. The WEEBLug comes with hardware for mounting to a rail or 1/4 inch through hole.

Grounding the entire array is even easier! Simply mount one WEEBLug for each rail, making sure the teeth will penetrate into the aluminum rail. (The lug itself is tin plated copper and the washer is stainless, so that connection can be pressure only.) The lug is a lay-in type, making it easy to attach the ground wire. Because you don't have to run ground wire to every single module, you save time and make a much cleaner installation.

How is this safer?

The WEEBLug and other members of the WEEB family are design to conduct thousands of amps safely. When they do fail - at extremely high currents - the WEEB washers fail in a safe manner. Most of the heat is generated right at the teeth so they and the surrounding aluminum melt and open just like a fuse. Because the washer is sandwiched between two large metal pieces, the small amount of melted material is safely contained.

What is a WEEB?

WEEB stands for "Washer, Electrical Equipment Bonding". The WEEB family of products are used to bond solar modules to solar mounts. The mounts are then grounded so the entire assembly is grounded. The WEEB family consists of six products: WEEB-9.5, WEEB-DMC, WEEB-PMC, WEEB-SMC, WEEB-UMC, and WEEBLug.

Why Should I Use WEEBS?

• It saves you time!
  • ...No more running ground wire to every PV module.
• It's safe.
• ...Meets UL467 requirements for bonding/grounding systems.
• It's reliable.
• ...Patented design features stainless steel teeth that pierce into anodized aluminum, providing a gas tight connection which prevents oxidation.
• ...Gives more consistent results than the method of scraping off the anodized coating by hand and using star washers.

All six products have been tested according to UL467 and are listed with Intertek, a National Recognized Testing Laboratory (NRTL). The products use patent pending technology for bonding anodized aluminum surfaces together. Bonding PV modules to a mounting structure removes the need to wire the modules separately: just the mounting structure needs to be wired to ground.
