LA15QS Series - Very Fast-Acting Semiconductor Fuse

Littelfuse’s LA15QS series Semiconductor fuses were designed for the specific protection of diodes and other semiconductor devices rated 150VAC/DC. The LA15QS product lines compact design is perfect for those applications that have limitations on available space.

Features

Low l2t minimizes damage to protected components on short circuit.
Controlled arc voltage reduces stress to circuit components during fuse clearing.
Choice of mounting types provides options for unique termination requirements.
Indicator options allow identification of blown fuses.

Applications:

Protection of heavy duty devices such as electromechanical rectifiers.

Help	Property	Value
It is established by Littelfuse as a value of current which the fuse, fuseholder, fuse clip or other fuse accessory can carry, based on a controlled set of test conditions. Close Info	Ampere Rating (A)	400
The maximum RMS AC voltage and/or the maximum DC voltage at which the fuse is designed to operate. For example, fuses rated at 600 volts and below may be applied at any voltage less than their rating. There is no rule for applying AC fuses in DC circuits such as applying the fuse at half its AC voltage rating. Fuses used on DC circuits must have DC ratings. Close Info	VDC (V)	150

Refers to how rapidly the fuse responds to various current overloads. Fuse characteristics can be classified into three general categories: very fast-acting, fast-acting or Slo-Blo® (time delay)fuse. The distinguishing feature of Slo-Blo fuses is that these fuses have additional thermal inertia (surge withstand) designed to tolerate normal initial or start-up overload pulse.
