BUSSMANN 170M4218 Semiconductor Fuse, 800 A, 690 VAC

Bussmann 170M4218 semiconductor fuse safeguards sensitive semiconductor devices from damaging current surges, ensuring equipment longevity and preventing costly downtime. It is ideal for industrial sectors such as power electronics, renewable energy systems, motor drives and electric vehicle components.

Working Mechanism:

• Bussmann 170M4218 semiconductor fuse safeguards electronic circuits with semiconductors from excessive current.
• When the current surpasses a safe limit, a fusible link within the fuse melts, breaking the circuit and preventing damage to sensitive components to stop overcurrent issues from harming semiconductor devices.

Features:

• Bussmann 170M4218 semiconductor fuse has square body blade design for increased surface area and facilitates adequate heat dissipation.
• It has a bolt-down termination style that ensures secure and reliable electrical connections.
• This high speed 800A fuse features bolt-down termination style that enhances electrical connection reliability to securely fasten the fuse to the circuits and fuse holders.
• It has current and voltage ratings of 800A and 690VAC, respectively.
• This car electric fuse has high speed interruption to quickly disconnecting the faulty circuit.

Frequently Asked Questions:

Q. What is the advantage of a fuse over a circuit breaker?

A.

• Fuses are cheaper and simpler than circuit breakers.
• Fuses interupts faster than circuit breakers to overcurrent conditions.

Q. How do I know when Bussmann 170M4218 fuse has blown?

A. The fuse will appear visibly melted and there will be an open circuit, meaning no continuity when tested with a compatible or suitable Southwire multimeter.

Q. What is the difference between a fuse and a breaker?

A. A fuse uses a metal element that melts when the current flows through it exceeds a certain level, breaking the circuit. The breaker, on the other hand, uses a mechanical mechanism to open and close the circuit.
