The Multiquip 406019 Circuit Breaker 10 Amp is a genuine OEM electrical protection component designed for SP3035, SP6057, SP4, and SP6457 series pavement and flat saws. This direct-replacement part matches the original specification, ensuring a correct installation with no adaptation required to your existing wiring harness. Sourced directly from Multiquip, the part is the exact part your machine was built with, giving you confidence in fitment across the full range of compatible SP-series saws.
Key Features
- Correct Amperage Rating — Rated at precisely 10 amps to match the original electrical circuit load specification on compatible SP-series saws, preventing nuisance trips or under-protection.
- Genuine OEM Component — Manufactured to Multiquip's original design tolerances, ensuring correct terminal sizing and trip characteristics for this electrical circuit.
- Broad SP-Series Compatibility — Fits SP303516, SP303520, SP303526, SP303530, SP605716, SP605720, SP605726, SP605730, SP605736, SP6457, and SP4 pavement and flat saw models.
- Direct Plug-In Replacement — Replaces the original breaker in the same mounting position with matching connector terminals, making installation straightforward.
- Electrical Circuit Protection — Protects onboard electrical components from overcurrent damage; a failed or incorrectly rated breaker can leave ignition and control circuits exposed to shorts or cause repeated electrical failures.
- Verified Multiquip Part — Part 406019 is the authorised Multiquip replacement, so you are sourcing exactly what the machine was designed to use.
A circuit breaker serves as the electrical safety valve for your saw's onboard wiring system. It monitors current flow and trips automatically if the circuit draws more amperage than it is rated for, cutting power before wiring, switches, or control components can be damaged. On SP-series pavement and flat saws, a functioning 10-amp breaker is essential to protect the ignition and auxiliary electrical circuits during operation. When a breaker wears out or fails to reset reliably, it can cause intermittent power loss to critical systems or leave electrical components unprotected — replacing it promptly with the correct-rated OEM part restores proper circuit protection and keeps the saw operating as intended.
