Fuseholders are electrical safety devices that use a replaceable fuse module to protect the circuit or load from overload and short circuits. The 01210004H fuseholder is an IEC 1 pole 4mm fuseholder designed to protect low voltage AC systems. It is designed to provide a reliable and efficient interface between the power supply, fuse and low voltage equipment. It is approved to UL and IEC standards and is suitable for use in both indoor and outdoor applications.

01210004H Application Field

The 01210004H fuseholder has a UL rating of 97 x 97 CSA, 400/600V, 10A. It is a IEC 1 pole 4mm fuseholder with a range of applications including controlling and protecting the electronic equipment in a variety of industries. Examples include control and motor circuits for industrial automation, lighting, HVAC, pumps, computers and communication systems.

01210004H Working Principle

The 01210004H fuseholder has a replaceable fuse module with a contact structure that allows the fuse to be released and inserted into the holder without having to disassemble it. The fuse consists of a replaceable wire element that carries current under normal operating conditions, and a heat sensitive device that will open the circuit under an overload or short-circuit condition. The fuseholder is equipped with a range of automatic reset options, that will stop the fuse blowing when the over current condition is cleared, and will automatically reset the fuse without the need to manually reset it.

The basic principle behind the 01210004H fuseholder is that when a short-circuit or overload condition occurs, the fuse element will typically melt or vaporize, causing an open circuit condition between the power supply and the protected load. This will prevent any further electrical chain movement that could otherwise result in permanent damage to the equipment or the user.

The fuseholder is made of highly durable materials, and with the proper care can last for many years. The fuseholder should always be checked prior to use, and should be replaced at regular intervals as per manufacturer\'s specifications. It is recommended that the fuseholder be checked for wear and tear, and that the fuse should be replaced as it may have degraded over time.

Conclusion

The 01210004H fuseholder is a reliable, safe and efficient fuseholder designed for use in a range of applications. It is approved to UL and IEC standards and is suitable for use in both indoor and outdoor environments. It has a reliable contact structure that allows the fuse to be released and inserted into the holder without having to disassemble it, and it features a range of automatic reset options that will stop the fuse blowing when the over current condition is cleared. With the proper care and maintenance, the fuseholder can serve the user for many years.
