Fuse holder (porcelain) Eti-Polam K DIII 63A E33 002333001

Eti-Polam porcelain fuse holder K DIII 63A (model E33) is a ceramic-bodied holder designed for DIII-size cartridge fuses. It provides insulated seating and reliable mechanical support for a 63 ampere overcurrent protective element in distribution boards and industrial switchgear. The porcelain construction offers electrical insulation and heat resistance suitable for fixed installations where safe, durable fuse mounting is required.

Advantages

The porcelain material ensures high dielectric strength and thermal stability under normal operating loads. The holder is configured to accept standard DIII cartridge fuses, enabling straightforward replacement and maintenance. Its design secures firm electrical contact and mechanical retention, reducing the risk of accidental disconnection. The component is compact and intended for panel- or rail-mounted applications in industrial and commercial electrical installations.

Suitable for

• Distribution boards and electrical panels requiring 63 A overcurrent protection
• Industrial switchgear and machinery control cabinets
• Applications where ceramic insulation and heat resistance are needed
• Maintenance and service environments that use DIII cartridge fuses

Key specifications

• Rated current: 63 A
• Compatible fuse size: DIII cartridge fuses
• Body material: porcelain (ceramic) for electrical insulation
• Mounting type: panel or rail mounting for distribution boards and panels
• Contact and retention: designed for secure electrical contact and mechanical fixation

How to use

Install the porcelain fuse holder into the panel cutout or mounting rail according to the panel layout and local wiring standards. Fit the correct DIII cartridge fuse of appropriate 63 A rating into the holder and verify firm seating and contact. Connect incoming and outgoing conductors to the holder terminals, ensuring terminations are tightened to the specified torque and insulated as required. Follow established safety procedures: de-energize circuits before installation or maintenance and verify correct protective device coordination.

Usage recommendations

Use fuses with appropriate characteristics for the circuit (time-delay or fast-acting as required) and ensure proper coordination with upstream and downstream protective devices. Periodically inspect the holder and contacts for signs of thermal stress, contamination, or mechanical wear and replace components if deterioration is found. Adhere to local electrical codes and manufacturer guidelines when installing and servicing the holder.
