BUSSMANN LPJ-350SP Low Peak Fuse, 350 A, 600 V

Bussmann LPJ-350SP fuse prevents overcurrent or short circuits. It is useful in motor circuits to permit sudden inrush during startups but prevent surges during current fluctuations.

Working Mechanism:

• When the current flowing through the circuit during normal operation is within the safe range, the fuse remains stable and the circuit functions normally.
• When an overcurrent occurs, the delay mechanism begins to react, but reaching a critical point takes time.
• The delay activates the fuse's tripping mechanism once it has absorbed enough heat.
• The fuse opens the circuit when the tripping mechanism is activated, preventing excessive current from causing damage.

Features:

• Bussmann Low-Peak LPJ-350SP fuse has two elements for both time-delay and current-limiting functions.
• Its long time delay reduces the number of unnecessary fuse openings caused by temporary overloads.
• This fuse's current-limiting capability protects downstream components from the thermal and magnetic effects of short-circuit currents.
• It has bolted blade ends for tamper-proof connections.

Compatible Accessories:

• Bussmann BH-3145 Fuse Module: This module is useful for easily installing the brand's LPJ-350SP fuse to any electrical circuit.

Frequently Asked Questions:

Q. Is this fuse indicating or non-indicating?

A. This is a non-indicating fuse. But if you want an indicating fuse with similar configurations, check out Bussmann LPJ-350SPI fuse.

Q. How do I choose the appropriate time delay fuse rating?

A. Selecting the right fuse rating involves considering the normal operating current of the circuit, the inrush current during startup and the maximum sustained current that the equipment can handle.

Q. What is the response time of this fuse?

A. Bussmann LPJ-350SP fuse has a response time of 10 seconds at 500 percent of the rated current capacity.
