Overview

The Mersen GPM-WT90 is a 30A, 600VAC/DC water-tight panel mount fuse block designed for industrial applications requiring reliable, moisture-resistant fuse protection. This 90° right-angle fuse holder accommodates 1-1/2" x 13/32" midget fuses (GPM-WT90) or Class CC fuses (GPM-WTR90), with 1/4" quick-connect/solder terminals for secure, vibration-resistant connections. The water-tight screw knob design prevents moisture ingress, making it ideal for outdoor enclosures, marine environments, and wet or dusty industrial settings. Key features include a maximum current rating of 30A, 600VAC/DC voltage rating, and compatibility with Mersen ATQ, ATM, TRM, OTM, GGU, A13X-2, A25Z-2, A60Q-2, and A6Y-2B fuse types (GPM-WT90) or Class CC fuses (GPM-WTR90). The patented design allows the same fuse holder body to accept either screw or bayonet knobs, providing installation flexibility without compromising performance. The flange design enables both front and rear panel mounting, simplifying integration into existing systems. Constructed with glass-filled polyester (PET) insulators, the GPM-WT90 delivers superior dielectric strength and mechanical durability for long-term performance in harsh industrial environments. The right-angle terminal orientation reduces cable bending stress, while the water-tight screw knob ensures reliable operation in challenging conditions. With a short-circuit current rating (SCCR) of 100kA for midget fuses, this fuse block is engineered for trouble-free installation and maintenance in critical applications such as power distribution, control panels, and machinery protection systems.
