• Maintenance replacements to restore original protection levels without altering panel wiring.
• New installations in 3‑phase systems where neutral or dedicated line protection is necessary.

How to verify compatibility

Notes: Confirm fit and ratings before ordering. Part number is the best reference for compatibility.

Practical tips for installation and operation

• Match the breaker’s 415V rating with your panel’s electrical service specifications and 3‑phase distribution plan.
• Ensure your enclosure and mounting arrangement support a 4-pole device and follow the manufacturer’s installation guidelines for secure operation.
• Plan for routine protection alignment—verify conductor sizing and upstream protection align with a 63A rating to avoid nuisance tripping.

With the ABB DS63A, you gain a targeted, reliable protection solution that aligns precisely with your 63A, 4‑pole, 415V requirements—from retrofit projects to essential replacements.
