Pertanyaan yang Sering Diajukan
Pertanyaan umum tentang BUSSMANN dari 3G Electric.
What is the difference between BUSSMANN LPT and KLU series fuses?
The BUSSMANN LPT series is a Class T, time-delay cylindrical fuse rated up to 600 V AC and 300 V DC, with current ratings typically up to 40 A. It is designed for branch circuit protection in panelboards and switchboards. The KLU series is a Class L, time-delay bolt-on fuse rated up to 600 V AC and higher currents (e.g., 650 A). Class L fuses are used in main feeder circuits and large industrial loads. The LPT has a cylindrical body for clip mounting, while the KLU has a bolt-on body for bolted connections.
Are BUSSMANN FNA series fuses indicating or non-indicating?
The BUSSMANN FNA series includes both indicating and non-indicating models. For example, the FNA-1/2 (500 mA, 250 V AC) is an indicating fuse, meaning it has a visual indicator that shows when the fuse has opened. Other FNA models may be non-indicating. Always check the specific part number's datasheet to confirm the indicating feature. The FNA series is a midget, time-delay cylindrical fuse with a 13/32 in x 1 1/2 in size, commonly used in control circuits and instrumentation.
What fuse types does the BUSSMANN S-8301-1-R fuse block accept?
The BUSSMANN S-8301-1-R is a 1-pole open block design for glass and ceramic fuses. It accepts a wide range of fuse types including 311, 312, 313, 314, 315, 322, 326, 3AG, ABC, ACG, GAB, GBB, GDL, GDV, GGC, GSA, MDA, MDL, MDQ, MDV, MDX, and MMB. These are primarily 1/4 in x 1 1/4 in or similar cylindrical fuses. The block is rated for 300 V AC and is UL Recognized. It is suitable for panel mounting in industrial control panels.
Can BUSSMANN CB222 circuit breakers be used in automotive applications?
Yes, the BUSSMANN CB222 series is designed for automotive and DC applications. The CB222-30 model, for example, is a Type II ATC footprint circuit breaker rated for 12 V DC with an interrupt rating of 225 A at 14 V DC. It uses a blade terminal connection for plug-in mounting in standard ATC fuse blocks. These breakers are auto-reset (Type II) and are commonly used in auxiliary circuits, battery protection, and aftermarket automotive electrical systems.
What is the voltage rating of BUSSMANN FWA series semiconductor fuses?
The BUSSMANN FWA series semiconductor fuses are rated for both AC and DC operation. For example, the FWA-70B is rated at 150 V AC and 150 V DC. These fuses are fast-acting and bolt-on, designed to protect power semiconductors such as diodes, thyristors, and IGBTs from overcurrent. The voltage rating varies by model; always verify the specific part number's datasheet for exact ratings. The FWA series is available in current ratings from a few amps to hundreds of amps.
Does 3G Electric stock BUSSMANN power distribution blocks?
Yes, 3G Electric stocks BUSSMANN power distribution blocks, such as the 16021-2 model. This is an open-style block with lug terminations, designed for surface mounting. It accepts line-side wire sizes from 14 AWG to 2/0 AWG and is made of aluminum. These blocks are used to distribute power from a single input to multiple outputs in industrial control panels and switchgear. 3G Electric carries a range of BUSSMANN distribution blocks with different pole configurations and wire size ranges.
