170M Series Details

Fast-acting fuses for DC applications. Designed for battery protection and energy storage systems.

FWP series fuses offer high performance in DC protection applications with excellent interrupting ratings.

FWP Series Details

Current-limiting fuses designed for motor protection. Provides excellent motor-starting capability.

LPJ and LPS series fuses are ideal for motor protection applications where high motor-starting currents are expected.

Low-Peak Details

Protect variable frequency drives from semiconductor damage with precisely coordinated fuses.

Ensure reliable operation of uninterruptible power supplies with appropriate fuse protection.

Preserve valuable electronics with fuses specifically designed for sensitive components.

Protect rectifiers, inverters, and other power electronics from destructive overcurrents.

High-speed fuses offer precise I²t characteristics, allowing proper coordination with upstream and downstream devices.

These fuses operate faster than the half-cycle point, limiting the let-through energy to protect sensitive components.

Current-limiting design significantly reduces fault current magnitude and energy let-through.
