Installation and compatibility notes
- Verify fit and ratings before ordering. The part number MHL26400 is the best reference for compatibility with your panel or enclosure.
- Ensure your equipment is rated for 600V and that the 400A current rating matches the system load and conductor sizing.
- Consult your electrical drawings and follow local electrical codes. A licensed electrician should perform installation and verification.
Practical tips
- Keep a spare MHL26400 in your maintenance stock for quick swap-outs during preventive maintenance or unexpected outages.
- Document the breaker’s location, rating, and panel compatibility to streamline future replacements and inspections.
- Cross-check the existing protective device family to avoid mismatches in trip characteristics and coordination with adjacent breakers.
