Overview

The Mersen 61007SJ is a 2-pole Class J fuse block designed for robust industrial circuit protection. It is rated for 600 Volts AC and 600 Volts DC at 100 Amperes. This fuse block features box side-clip connectors, utilizing spring-reinforced, tin-plated copper clips for secure and high-conductivity contact. The insulator is constructed from molded glass-filled polycarbonate (GFPC), providing dielectric strength exceeding 2500V for reliable operation. The Mersen 61007SJ is compatible with Class J fuses such as AJT, A4J, and HSJ. It is engineered for field assembly of multi-pole blocks. The fuse clips are specifically designed for 200-600A bladed Class J fuses and offer a 200kA SCCR (Short-Circuit Current Rating) for fault protection. This fuse block is suitable for applications including motor control centers, switchgear, and industrial distribution panels where reliable overcurrent protection is essential. The wire range for this specific model accommodates stranded or solid copper and aluminum conductors from #6 AWG to 350 kcmil. All Mersen Class J fuse blocks meet the requirements of UL4248 and are UL listed (Guide IZLT, File E52283) and CSA certified (class 6225, File 32169).

Fuse supports, non-disconnecting, are used primarily in potential transformer circuits, or where there is some other disconnecting or isolating device in series with the fuse in the circuit. Disconnecting switch devices have the additional feature of serving to isolate the equipment they protect. It should be noted that disconnecting switches are not load-breaking devices, therefore, the circuit must be open prior to the fuse disconnection. Select either a fuse support or a disconnecting switch for each fuse. Fuse supports and disconnecting switches include live parts for both ends. Both fuse supports and fuse disconnect switches can be mounted vertically or horizontally. The type EK are used for indoor installations while the type EKO are used outdoors. 25800 Volts EKO-1C CHM series.
