Morris Products ATC-3 Automotive Blade Fuse 3A 32VDC

Product Description

The MORRIS PRODUCTS ATC-3 is a fast-acting automotive blade fuse rated at 3 amps and 32 volts DC, designed for use in automotive electrical systems and low-voltage control circuits. The fuse element is constructed from tin-plated zinc for corrosion resistance and reliable conductivity, housed in a polycarbonate body. With an interrupting rating of 1 kiloampere, it handles fault current safely in light-duty vehicle and control circuit applications. The violet color coding follows industry-standard ATC fuse identification, allowing technicians to confirm amperage at a glance without checking markings. It is lead-free, halogen-free, and RoHS compliant. Licensed electricians, automotive technicians, and low-voltage control system installers are the typical end users for this part.

The ATC-3 is suited for standard ATC blade fuse holders found in automotive fuse panels, low-voltage control circuits, and similar applications requiring a 3-amp fast-acting protective device. The wide operating temperature range of -40 to 100 degrees C makes it appropriate for underhood automotive environments and outdoor control enclosures subject to temperature extremes. Test points on the housing on applicable packages can assist in live-circuit diagnostic work without removing the fuse from its holder. Country of origin is the USA.

Key Features

• Fast-acting characteristics for rapid overcurrent response in automotive and low-voltage circuits
• Industry-standard violet color coding for immediate 3-amp identification
• Tin-plated zinc terminals resist corrosion and maintain low contact resistance
• Wide operating temperature range: -40 to 100 degrees C for extreme environments
• Lead-free and halogen-free construction; RoHS compliant
• UL Recognized for use in low-voltage control circuits (UL 94 approval)

Compatibility

Designed for standard ATC-style blade fuse holders used in automotive fuse panels and low-voltage control circuit applications requiring a 3-amp, 32 VDC fast-acting fuse.

Installation Notes

Automotive technicians and licensed electricians typically install ATC blade fuses as part of circuit protection service. Always disconnect the power source or turn off the ignition before replacing a fuse to prevent arc flash or unintended circuit activation. Confirm the replacement fuse amperage matches the circuit rating before inserting; substituting a higher-amperage fuse can damage wiring and components. Low-voltage control circuit installations should comply with applicable NEC requirements for the circuit type.
