Overview – COVER-CB BOX-MTO 319-3151
Engineered for Cummins electrical enclosures as the circuit-breaker box cover, the Cummins COVER-CB BOX-MTO 319-3151 meets the tolerances your equipment was designed around.
Parts Characteristics
A circuit-breaker box cover that closes and protects the breaker enclosure from dust, moisture and impact. It maintains the IP rating the electrical safety depends on, so a sound cover keeps the breakers alive and the bay safe.
Applicable Models & Applications
Fitted to Cummins breaker enclosures of this shape. Match the cover outline, latch and gasket against your old cover – covers that look alike differ in how they seal and latch.
Maintenance & Replacement
Inspect the cover for cracks, a failed latch and a hardened gasket at every electrical service. A cover that no longer seals lets dust and moisture into the enclosure, and breakers fail in a dirty, damp bay.
Replace the gasket with the cover. A new cover onto an old, flattened gasket still leaks, and the leak is what kills the breaker.
Confirm the cover latches home and the enclosure is dry before closing. A cover forced over trapped wiring cracks at the latch and the seal is lost from the start.
Keep the common breaker-box covers for your model on the shelf. They are cheap, they protect an expensive enclosure, and they are exactly the part missing when a box needs closing today.
Price Reference (USD)
