When to Replace

• Existing breaker fails to trip during an overload or short-circuit event.
• Nuisance tripping occurs under normal, rated current loads.
• The manual reset lever is broken, loose, or will not stay in the "ON" position.
• Visible signs of damage, such as a cracked housing or severe corrosion on terminals.
• As an upgrade from a standard 150A fuse to a resettable circuit protection device.

Installation Tips

• Always disconnect the battery or power source before starting installation.
• Install the breaker as close to the power source as possible to protect the main power wire.
• Ensure wire-to-terminal connections are secure using properly crimped ring terminals to prevent overheating.
• Use a wire gauge appropriately sized for a 150A load to avoid voltage drop and fire risk.
• Do not use the manual trip lever as a routine power switch.
