Tomzn TZG40-C Replacement Cartridge HN Electric

The Tomzn TZG40-C replacement cartridge is designed for customers who already have a compatible Tomzn TZG40-C AC Surge Protection Device and need to replace the removable protection module. Instead of replacing the complete SPD assembly, a compatible replacement cartridge can make maintenance simpler and more economical.

Surge protection devices are installed to help protect electrical installations and connected equipment from transient voltage surges. The Tomzn TZG40-C range is designed for AC electrical systems and is available in configurations intended for surge protection applications. The manufacturer-listed TZG40-C 2-pole AC SPD is rated for AC applications up to 275V and has a stated surge current range of 20kA–40kA.

A replaceable cartridge is particularly useful for electrical panels where the SPD has reached the end of its service life or the protection module needs to be changed. The modular design means you can replace the relevant cartridge rather than automatically purchasing another complete surge protection device.

Before ordering, check the model and electrical specifications of your existing SPD carefully. This cartridge is intended for the Tomzn TZG40-C system, so compatibility should be confirmed before installation. Pakistani listings show variants associated with 275V and 440V, making it especially important to select the correct version for your installation rather than assuming every cartridge is interchangeable.

For electricians, solar installers, maintenance technicians and homeowners maintaining an electrical distribution board, keeping a spare Tomzn TZG40-C AC SPD replacement cartridge can reduce downtime when the existing protection module needs replacement.

HN Electric provides electrical protection products for customers in Lahore and across Pakistan. If you’re unsure which cartridge is suitable for your existing Tomzn SPD, compare the model, voltage rating and cartridge configuration before placing your order.

Important: SPD replacement should be carried out by a suitably qualified electrician. Always isolate the electrical supply and follow the manufacturer’s installation requirements before replacing a protection module.
