Pollak 54-730 30 Amp Type II Modified Reset Circuit Breaker – Blade Terminal Plug-In

Provide professional-grade protection for your vehicle’s high-amperage circuits with the Pollak 54-730 30 Amp Circuit Breaker. Designed as a high-performance, plug-in replacement for standard 30A automotive blade fuses, this Type II breaker is the ideal solution for heavy-duty truck and trailer electrical systems.

The 54-730 features a Modified Reset (Type II) design, also known as a "non-cycling" breaker. When an electrical overload or short circuit occurs, the breaker trips and remains in the "off" position as long as power is supplied to the circuit. It will only reset once the power source is manually turned off, allowing the internal bi-metal strip to cool. This critical safety feature prevents the repetitive, rapid cycling common in Type I breakers, which can lead to excessive heat buildup and damage to sensitive equipment like high-output blower motors, power seat adjusters, and auxiliary lighting arrays. With its standard blade terminal design, it installs instantly into existing fuse panels, eliminating the need for disposable fuses and reducing maintenance downtime.

Key Features:

• Type II Modified Reset: Stays tripped until power is removed; ensures the operator investigates the fault and protects against wiring fatigue.

• 30 Amp High-Capacity Protection: Specifically rated for high-draw 12V DC auxiliary circuits and heavy-duty truck accessories.

• Direct Blade Plug-In: Replaces standard automotive blade-style fuses (ATO/ATC) in existing fuse blocks without any wiring modifications.

• Rugged Metal Construction: Industrial-grade metal housing provides superior heat dissipation and vibration resistance in commercial environments.

• Reusable Efficiency: A permanent alternative to blown fuses, perfect for managing circuits prone to intermittent overloads.
