Product details

63 A, 2-pole C-curve MCB for distribution boards

Breaking capacity is 4.5 kA Icn at both 230 V and 400 V AC, 50/60 Hz, conforming to IEC 60898-1. That's a practical advantage for panel builders who want to avoid nuisance swaps after a fault event.

Rated insulation voltage 500 V AC, operational voltage 400 V AC. Pollution degree 2 (normal, non-conductive pollution only). Suitable for isolation per IEC 60898-1 — the contact position indicator confirms open/closed state visually, which helps during panel commissioning and lockout/tagout procedures. Tropicalisation class 2 (protected against damp heat). Tightening torque 3.5 N·m on tunnel terminals.

Frequently asked questions
