Fuseholders provide a secure way of connecting a fuse for electrical protection by limiting the current to a machine and preventing it from becoming overloaded. CHM1DNU fuseholders are designed for use in AC and DC applications with fuses complying with IEC 60079-1 and UL 248-14. The fuseholders feature dual-in-line construction, snap-in mounting, and various mounting hole configurations.

The CHM1DNU has two stud-mounted terminals that accept a fuse. The terminals are recessed into the housing of the fuseholder to provide secure contact with the fuse as well as allowing the fuse to be easily removed and replaced. The CHM1DNU has snap-in mounting capabilities that allow it to be quickly and securely mounted to any surface. The housing of the fuseholder is made from durable thermoplastic and it also has an integrated LED indicator for indicating whether a fuse is inserted or removed from the frame.

The working principle of the CHM1DNU fuseholder is simple: when the current rises above the rated value, a bimetallic strip attached to the contacts heats up and bends. This causes a switch to be opened, breaking the connection and preventing further current from flowing. This ensures that the fuseholder is able to protect the machine against overloads and short circuits. During normal operation, the LED indicator will glow, indicating that the fuse is in place.

CHM1DNU fuseholders are suitable for use in medium voltage applications, including industrial control circuits, motor control circuits, lighting circuits, and power supplies. They are available in various sizes and can accommodate fuses with a range of current ratings. The housing of the fuseholder is designed to provide maximum durability and resistance to harsh environments. The terminals are thermally compensated for superior accuracy and repeatability under variable temperature conditions.

In addition to their use in medium voltage applications, CHM1DNU fuseholders can be used in high voltage applications, such as wind turbines and PV (photovoltaic) arrays. They are designed to provide reliable protection in these applications and are rated for use up to 1,000V AC. They are also suitable for use in a variety of outdoor conditions, including rain, snow, and extreme temperatures.

The CHM1DNU fuseholder is an effective and durable solution for applications requiring secure and reliable protection against overloads and short circuits. With its low profile design, snap-in mounting capabilities, thermally compensated terminals, and integrated LED indicator, the CHM1DNU is the perfect solution for use in a wide range of AC and DC applications.
