The design standard for fuse block overcurrent protection
Wohner's AMBUS® EasySwitch Fuse Blocks feature the latest enclosed design for the ultimate in safety an convenience. Built for control and power circuits, the AMBUS line is DIN-rail mountable, compact and reliable. Both AC and DC models are available, with and without blown fuse indication.
Sized for many applications
AMBUS Fuse Blocks are available in one, two and three pole configurations for the following fuse types:
Midget; 1-1/2 x 13/32
DC rated fuses up to 30A
Class J 30A fuses
Class J 60A fuses
All AC fuse blocks are rated to 600V, with 12-72V AC/DC models available for midget and Class CC fuses. All devices carry a withstand rating to 200kA. Midget fuse blocks are rated to 50kA.
Enclosed design offers many advantages
Unlike "open" fuse blocks that were extremely dangerous, the enclosed design of the AMBUS series features IP2 dead-front construction under IEC and DIN standards. In operation, there is no access to live fuses or fuse clips. With the flip of a finger, fuse access is gained via a levered compartment on the front of the holder that isolates the fuse from the line power. This makes fuse changeout quick, easy, convenient....and SAFE.
Other great features
The AMBUS line is compact, saving up to 15% in panel space over conventional fuse blocks. The entire line is also DIN-rail mountable, resulting in extra savings in panel building time. All models are available with blown fuse indication, saving time on maintenance and troubleshooting. The bodies are made up of tough and durable polyamide, known for its exceptional insulating properties. Wire terminals accept multiple conductors, and UL 508 approved bus bars can be used to quickly distribute power to many AMBUS Fuse Holders simultaneously.
Class CC and J fuse holders are UL listed for branch circuit protection in electrical distribution systems. They are excellent for small motor loads and group protection of small motors. Midget holders are UL listed for control circuit protection. The entire line is CSA Approved and carries the CE Mark for use in international markets.
