3557-20

Fuseholders are integral components of an electrical circuit and must be chosen carefully. The type of fuseholder used depends on the current rating of the fuse, the application, and if the fuseholder must accommodate multiple fuses. The 3555-20 is an exceptionally reliable fuseholder that meets these requirements. It is particularly well-suited for applications such as power supplies, motor control setups, and power distribution.

The 3555-20 is a single-pole, PCB mount double-bolt fuse holder. It is an advanced design that meets the highest safety requirements for switching and overvoltage protection. All external and internal components of the 3555-20 are UL and CSA recognized. It can accept all standard types of fuse holders, up to 8.3 amps, and has a current rating of 30A/125V AC, 20A/250V AC, and 20A/30V DC.

The 3555-20 utilizes a fully insulated, durable housing and mounting brackets. It features front-of-panel-mounted convenience, which allows for easy installation and is safer for the user. The recessed clip allows it to easily hold two 1/4" x 1" fuses. The fuses are snugly nested in the 3555-20, ensuring a solid connection. The fuseholder also prevents the pin from moving and breaking. The unique locking mechanism ensures that once the fuses are secured in the fuseholder, they will not be jarred loose from vibration or other disturbances.

The 3555-20 is also highly resistant to shock, vibration, and corrosion. It is constructed from UL94 V-0 flame-retardant polycarbonate, which is non-conductive and resistant to deterioration from moisture and other environmental factors. It can handle temperatures between -40 F and +120 F. Additionally, the 3555-20 features a unique design that prevents contact overlap and thus reduces the risk of fires. It has a UL Recognized Operating Temperature of -25C to +105C.

The 3555-20 is a powerful yet compact piece of equipment. It is extremely reliable and easy to install, making it ideal for applications requiring higher power ratings. From motor control setups, power supplies, and power distribution to switching and overvoltage protection, the 3555-20 fuseholder is designed to meet the highest safety requirements and is the ideal choice for any of these applications.
