Products Description

Standard blade fuse 9C-2

Product Synopsis

The Standard Blade Automotive Fuse utilises a plug-in blade structural design. Its compact design and accurate fusing attributes offer cost-effective and efficient overload protection for automobile circuits. The device adheres to the IEC 60127-4 international standard, with a rated current of 5A-30A and a rated voltage of 32V DC. It operates reliably in a temperature range of -40℃ to +85℃ and is extensively utilised in automotive lighting, electronic control systems, battery management, and various other applications.

Technical specifications:

Fast-blow design: appropriate for resistive loads (e.g., automotive lights and cigarette lighters), promptly disconnects current during overload conditions;

Slow-blow design: capable of enduring transient surge currents, ideal for inductive loads such motors and compressors;

Standard plug-in configuration: thickness 4.8mm, compatible with universal fuse holders, and accommodates blind plug installation.

Advantages of the product

1. Cost-effective and efficient safeguarding

In comparison to conventional glass tube fuses, the blade construction incurs a 30% reduction in cost, and its plug-in form facilitates rapid replacement, hence decreasing maintenance time and expenses.

2. Broad thermal environment adaptation

The temperature cycle test ranging from -40℃ to +85℃ demonstrates steady performance in elevated temperature conditions, such as engine compartments, and complies with the SAE J1171 vehicle electrical safety standard. Environmental compliance assurance The shell is constructed from UL94 V-0 flame-retardant material, devoid of halogens and lead, and adheres to RoHS 2.0 (2011/65/EU) standards. It also accommodates customised lead-free packaging to fulfil the green supply chain mandates for new energy vehicles.

Application contexts

In automobile lighting systems, 5A-10A standard blade fuses safeguard headlights, taillights, and instrument panel backlight circuits, promptly interrupting the current in the event of a filament short circuit. Specifications of 15A-20A are appropriate for electronic equipment, such automotive audio systems and air conditioning controllers, to mitigate the impact of circuit variations on signals. A 30A slow-blow fuse is especially appropriate for inductive loads, including motor and compressor startups, as it can endure surge currents during initiation. Furthermore, the products are extensively utilised in truck circuits, motorcycle electronic fuel injection systems, and small engineering machinery, accommodating the circuit protection requirements of various models.

Selection and Installation Manual.

Principle of Current Selection: - Resistive load: Rated current equals 1.5 times the typical operating current; - Inductive load: Rated current equals 2 times the normal operating current (for instance, if the working current is 3A, select a 5A specification). Installation Considerations: - Operate only after disconnecting the power supply and utilise a specialised extraction tool to prevent electric shock; - Regularly inspect the fuse holder and eliminate any oxide buildup to ensure optimal contact.
