Automotive Maxi Auto Blade Fuse ATM 32V 20A 25A 30A 40A 50A 60A 70A 80A 100A 120A
Introduction Of The Automotive Maxi Auto Blade Fuse ATM 32V 20A 25A 30A 40A 50A 60A 70A 80A 100A 120A
Maxi blade fuse featured good time delay characteristics and low heat dissipation , ideal for motor powered applications where maybe bring large inrush currents.MAXI Fuses are primarily used for under hood applications and are produced with a high temperature polymer and silver plated blades. They replace the commonly used fusible wire or fusible link to protect a high current segment or system of the wiring harness.

Overcurrent Protection Glossary
Voltage Rating
The voltage rating is the maximum open circuit voltage in which a fuse or circuit breakers can be used, yet safely interrupt an overcurrent. Exceeding the voltage rating of a fuse may cause the fuse to open but may not allow it to safely clear an overcurrent condition.
Short Circuit
A short-circuit is an overcurrent condition where an abnormal, low-resistance, circuit path is introduced into the circuit. This low-resistance path bypasses the normal load and can create extremely high currents (up to 1000x the normal current under some conditions).
Interrupting Rating (Breaking Capacity)
The interrupting rating is also known as the breaking capacity or short circuit rating of any overcurrent protective device. The interrupting rating is the maximum approved current which the fuse of circuit breaker can safely interrupt and clear a short-circuit at the rated voltage.
Melting Time
The melting time is the period of time before the fuse element begins to melt during an overcurrent condition.
Ambient Temperature
The ambient temperature is the measured temperature of the air immediately surrounding the fuse or circuit breaker. Typically, the fuse or circuit breakers’ ampere rating is determined at “room temperature” or 23° C. Fuses and circuit breakers must be re-rated where temperatures vary from 23° C.
Ampere
An ampere is an international unit of measure based on the rate of flow of electrons in an electric circuit. One ampere is equal to the amount of current that will flow through one ohm of resistance under one volt of potential. (1A = 1V / 1Ω)
Ampere Rating
The ampere rating is the current carrying capacity of a fuse or circuit breaker (also collectively known as “over-current protective devices”). When a fuse or circuit breaker is subjected to a current above its ampere rating, it will open the circuit after a predetermined period of time.
