Fuses for Automotive

Fuses are electrical protective devices. They are made of a thermoplastic shell and a fusible link in Zinc (Zn) or Copper (Cu) alloy. MTA’s fuses are developed according to ISO standards, and their range covers blade and bolt down types.

MTA Automotive offers fuses suitable for traditional 12 V systems, as well for the now trending 48 electrical systems. 

Customized Fuses

The increasingly complex design of distribution boxes have led MTA to develop fuses with blades to be screwed, to be clinched, in some cases they may be bent, in other cases they can be designed as male counterparts for clip terminals of different sizes and shapes.

Of course, we offer fuseholders and housings as well. We offer high quality standard and custom made fuseboxes in materials depending on your application, typically PA6 and PBT. The bolts are made in stainless steel for high torque tensioning. The fuseboxes can be delivered pre-assembled with fuses and conductor rails for your convenience

MTA Compact Fuses

The Compact range has been developed to meet the latest demands of a market that requires smaller and lighter fuses. Simulation of real-world applications in fuseboxes have shown how MTA can obtain a considerable decrease in raw materials used, the size and the total weight of the finished product.

Fuses MTA MaxiCompact

Maxi Fuse Compact 

Blade type 

Compliant with ISO 8820-10 Standard (Type L, high current miniature).  Made of tin plated zinc alloy or silver plated copper.
Meat as substitute for MaxiVal and J-case fuses in the stated current range. They are smaller than the current solutions and accomodate thinner wires, thus eanbling space and weight saving.

Fuses MTA M8

M8Compact 

Blade type 

Family of blade fuses in development, complying with high current capabilities of Type “E” fuses (refer to ISO 8820-3 Standard) and with reduced dimensions as Type “L” (refer to ISO 8820-10 Standard). Made of Zinc alloy.

M8Compact Range combines the typical high-current performance of MaxiVAL fuses, which is meant to substitute, but requires 46% less space. The concept is the same adopted for the MaxiCompact range, with smaller tolerance ranges and higher self-heating performance.

MegaCompact

Bolt-Down Fuses 12/14 V

If compared to the MegaVAL, the MegaCompact allows for a reduction in area and volume of about 30 %.

Made of tin plated zinc.

PowerVal Fuses

The PowerVal line has been developed in order to safeguard loads as traditional starters and their feed systems both from electrical malfunction (overloading and/or short circuit) and mechanical problems (shaft stoppage and subsequent overcurrent).

MiniVAL

Blade type 

Compliant with ISO 8820-3 Standard (Type F). This medium slow fuse is the most popular standard in automotive protection for low cross-section wires. Made of Zinc alloy.

Datasheet

UniVAL / ATO Fuse 

Blade type 

Compliant with ISO 8820-3 Standard (Type C), the first standard automotive blade fuse. Made of Zinc alloy

Datasheet
Fuses MTA MaxiVal

MaxiVAL 

Blade type Fuses

Compliant with ISO 8820-3 Standard (Type E). Most applied standard to protect medium-heavy wires. Its slow blow operating characteristics allow high peak inrush currents with heavy duty cycle. Made of Zinc alloy.

Copper MegaVAL 70V

Bolt Down Fuses

This  70 Volt fuse series ranging from 100-500A with a standard fotprint of 50,8mm (same as standard Megafuse fuse). The benefits of standard CC 50,8mm are that excisting Megafuse holders could be used

PowerVal 

Bolt Down Fuses

PowerVAL / Power Fuse is a special series of fuses, with identical constructive characteristics of the MegaVal / Mega Fuse series, but with Operating TimeLimits tailored to protect Starter Motor Lines.

Main features:

  • Ohm value assessed and optimized to guarantee the lowest possible voltage drop on the line.
  • High Capacity to sustain heavy power surges
  • Operating time curve to ensure efficient protection of the entire range of electrical malfunctions
  • Made in Zinc alloy or Copper, to achieve the best performance for each application.

PowerVal Fuses for 48V Systems

The 48 V rated voltage fuses have been developed to support the most energy-demanding systems of electric and hybrid vehicles. Thanks to specific technologies, and enhanced performances, and according to international standards, the 48 V fuses can operate up to 70 VDC.

MidiVAL 

Bolt Down Type 

Compliant with ISO 8820-5 Standard, applicable to automotive bolt-on Fuses. They allow space reduction compared to MegaVAL® for high current wiring protection. The operating features are characterized by strong time delay characteristics. Made of Zinc alloy.

Datasheet

MegaVAL 

Bolt Down Fuses

Compliant with ISO 8820-5 Standard, recommended for the protection of heavy cross-section wires with heavy current duty.

Made of Zinc alloy (100 ÷ 250 A) and Copper (300A÷500A), to optimize the performance to the nominal current. Also available as with complete copper alloy (100 ÷ 250 A)
